What is DICOM?

DICOM stands for Digital Imaging and COmmunication in Medicine. It is a standard developed by the National Electrical Manufacturers Association (NEMA) in conjunction with American College of Radiology (ACR). It covers most image formats for all of medicine, and it also specifies messaging and communication protocols between imaging modalities and their utilizing modalities. In 1997, four DICOM extension modules for radiation therapy (RT Structure Set, RT Dose, RT Plan and RT Image) were added, the fifth RT module, RT Record, was added in 1999. Currently it supports 47 active modalities (CT, MRI, CR, US, PET, SPECT…). Unfortunately as stated in the DICOM standard, the DICOM Standard committee does not provide any implementation details of any features of the standard, nor does it specify overall set of features and functions to be expected from specific systems, or provides procedures to test/validate an implementation’s conformance to the standard. It is the manufacturers’ responsibilities to comply with this standard and make their implementation interchangeable with others. When incompatibility problems occur, the end users usually do nothing but wait for a new release.

What is DICOMan?

Despite the fact that DICOM-RT was devised in 1997 and has currently been adopted by all major manufacturers, the DICOM-RT viewer is not readily available to many healthcare providers and R&D scientists and engineers in the field of radiation therapy. When said “YES” to radiation oncologists, the author started developing a tool, named DICOMan, for himself to solve clinical problems. It is a DICOM/DICOM-RT viewer enhanced with a set of built-in tools such as DICOM Decompressor, DICOM Pusher, DICOM Retriever, DICOM Editor, DICOM Anonymizer, DICOM Format Converter and so on. DICOMan is such a software system that aims to help tackle DICOM incompatibility problems in DO-IT-YOUSELF manner which is much faster than waiting for manufacturer’s new release or patches. It helps you address DICOM issues to meet immediate clinical needs.

Why Do You Need DICOMan?

Image Guided Radiation Therapy (IGRT) is the next-generation of technology for high precision radiotherapy, a state-of-the-art technology that combines planning and in-room imaging of the patient’s targets in the treatment position, before treatment delivery, and the images can be examined on on-line or off-line, for optimization of the accuracy and precision of the radiotherapy. Four-dimensional imaging, PET/CT, MRI, Computed Radiography, Ultrasound, and online portal imaging modalities, such as real-time x-ray imaging or cone-beam CT, are pouring much more image data into radiation therapy clinic in the current IGRT era than ever before. New emerging modalities such as MVCT are continuously joining this choir. All those imaging modalities are supposed to comply with DICOM standard, but in fact it takes time for manufacturers to adapt their systems to new imaging modalities with new features.

DICOM incompatibility problems may arise from various sources. A DICOM CD-ROM, for instance, is often the form of imaging studies of outer community patients. It is not unusual that images on those CD-ROMs can not be viewed because of corrupt built-in viewers or some corrupt image data. Sometimes images on good CD-ROMs can not be transferred to treatment planning workstations due to unsupported compression algorithms or the lack of a DICOM pusher.

A missing or incompatible tag in the DICOM file, inconsistent image dimension and so on can also make DICOM objects unacceptable by some systems. It often happens when the facility is installing new equipment or upgrading existing systems. With the help of DICOMan, one should be able to pinpoint the problem and fix it in the DICOM editor module. To retrieve previous imaging studies for planning purposes can become laborious because of too much unwanted data or the absence of attending staff. The built-in DICOM retriever finds and fetches the specified DICOM objects from PACS or imaging modalities whenever they are needed.

DICOMan is meant to tackle all those DICOM discommodities. With this application at hand, treatment planning and delivery of radiation therapy procedures will become practical in a timely fashion when those problems occur. As the DICOM standard evolving and new imaging modalities emerging, DICOM incompatibility problems will continue to occur. A fast adaptive DICOM application like this is very helpful for clinicians to view the imaging studies, register and fuse the diagnostic imaging for radiation treatment planning purpose, and image-guidance for treatment delivery. It is a time-consuming process to develop this application. Many of its features are available in many Radiotherapy Treatment Planning (RTP) systems.

THE AUTHOR HAS REINVENTED THE WHEEL SO THAT YOU DON’T HAVE TO.

For Whom is DICOMan Made?

All clinics, R&D departments of imaging and RT equipment manufacturers and research laboratories that need to handle DICOM and DICOM RT objects are the targeted users. It is especially useful for users in the fields of Radiation Oncology and Radiology.

Main Features of DICOMan

For detailed description of DICOMan features, you are referred to the online manual “DIOCMan.chm”. It is also included in the software package.

• View DICOM & DICOM RT Objects and Non-DICOM Images
  

This application was written in C++ from scratch. It was optimized on file parsing efficiency. Its GUI was made flexible and eye-friendly. Images of multiple studies of one or more patients can be viewed simultaneously in multiple image windows. Each image window can be maximized or even displayed in full-screen mode. Changing window and level, zooming in/out and panning are right at your finger tips. The tree window on the left side organizes DICOM objects in
hierarchical structure as stated in the DICOM standard. The drag-and-drop feature was implemented to make object rendering easy.

Compression algorithms have been integrated into this software seamlessly so that compressed images (it is very common for DICOM CD-ROM) can be decompressed and transferred to treatment planning systems that currently do not support compressed imaging studies. Please be advised that images on some CD-ROMs are not in DICOM format but in whatever format the built-in viewer reads.

The stack of planar image slices can be reconstructed into volumetric data in real-time and rendering in orthogonal view to help the user localize the region of interest.

Non-DICOM images of common formats (BMP, GIF, J2K, JBG, JPEG, PCX, PNG, RAW, TGA and TIFF) and the most popular dose distribution formats (dose distributions in DICOM format, such as of Eclipse and Helix, are of course supported) can also be viewed together with DICOM objects. Since Version 2.50, the most popular radiotherapy dosimetry formats can also be read and displayed. They are recognized by file name suffixes. The supported non-DICOM image formats are listed alphabetically as follows.

1. Bitmap (*.bmp)
2. BrainLAB iPlan dose map (*.flu)
3. CMS Focus/XiO dose map (*.cms)
4. GIF(*.gif)
5. JPEG 2000 (*.j2k or *.jp2)
6. JBG (*.jgb)
7. JPEG (*.jpg or *.jpeg)
8. PCX (*.pcx)
9. Philips Pinnacle³ dose map (*.header)
10. PLATO dose map (*.pla)
11. PNG (*.png)
12. PTW Seven29 ion chamber array measurement (*.mcc)
13. RAW (*.raw)
14. RIT film dosimetry version 4 (*.rv4)
15. TIFF (*.tif or *.tiff)
16. TGA (*.tga)
17. TomoTherapy dose map (*.header)
18. Varian Eclipse fluence (*.efl)
19. XRD X-Ray multi-framed image (*.his)
20. IMPAC RTP format (*.rtp)
21. Varian MLC format (*.mlc)

Figure 3 View radiotherapy dosimetry images.

It supports non-image DICOM objects such as RT Structure Set, RT Dose and RT Plan. RT PLAN module is extensively supported. It supports regular external beam radiation therapy plan including wedges and blocks, it also support IMRT plans using MLC or compensators. Ion beam radiation therapy is support as well. MLC segments either in step-and-shoot or sliding-window technique can be viewed interactively. It supports brachytherapy plan so that plan parameters such as machine features, source information and treatment channels can be extracted and tabulated. When reading RT DOSE module, DVHs and dose matrix can be tabulated or exported.

It also provides the users with a three-dimensional rendering engine (Figure 1).

• Push DICOM Objects

DICOMan can push any selected DICOM objects to remote listening DICOM storage servers that declare the supports for mentioned DICOM objects. It helps one move DICOM objects around. For instance, when compressed imaging studies on a CD-ROM need to be transferred to a radiation therapy planning (RTP) system which does not support that compression algorithm, DICOMan can be used to decompress imaging studies and pusher them over. When some RTP systems do not allow direct DICOM file deposit (it may impinge their databases), the DICOM pusher helps you transfer DICOM files.

Figure 4 The DICOM pusher.

• Retrieve DICOM Objects

When it is configured, it can find and retrieve seamlessly whatever imaging studies the user selected without extra junky data. It works just like a terminal workstation of a commercial PACS without extra hardware investment. To help you establish DICOM connection, the matching criteria for fetching study or series were made flexible so as to fit specific PACS setting. It is also equipped with a network analyzing tool for you to identify connection problem.

Figure 5 The DICOM retriever.

• Help Build Your Own RT PACS

DICOMan works seamlessly with ConQuest DICOM http://www.xs4all.nl/~ingenium/dicom.html that supports storage and query/retrieval services. DICOM objects from various imaging modalities and treatment planning systems can be transferred via DICOM connection to your in-house RT PACS where DICOMan retrieves DICOM RT objects and renders them wherever diagnostic and therapeutic information is needed. Powered with the world’s most popular open source database engine, MySQL http://www.mysql.com/, it can handle vast amount of image data with very efficient file retrieve. It is especially useful for case presentation in radiation therapy clinics equipped with various planning and delivery systems. To help you set up DICOM retrieval service between DICOMan and ConQuest DICOM, the author wrote a short technical note here
Set up DICOM Retrieval Service for DICOMan and Conquest DICOM.pdf.

Figure 6 Build your own DICOM RT PACS.

• Act as a DICOM Storage Server

The multi-threading programming technology was used to maximize the performance. It runs unnoticeably at the background and can be easily turned on or off. Figure 6 shows the configuration module for the storage server when it is to be started. A message window will be shown in the bottom-left corner of the main frame, indicating that the DICOM storage server is on and monitoring the communication process when receiving incoming DICOM objects.

Like no other, its “Parse Live” feature would let you see the incoming DICOM RT objects.

Figure 7 The configuration module for DICOM the starting storage server.

• Edit DICOM Objects

It works like a text editor in the DICOM world. It functions far more than common de-identification. In fact it is capable of editing all data elements. It can add, modify and delete any tag including sequence tag and propagate tag changes in one object to all siblings in the same series. For tags with large amount data, data can be extracted or be replaced with external data.

The editor can be configured in the form of a floating dialog as shown in Figure 1 or a child of a image window so that you can edit up to four DICOM objects at the same time. It is advantageous in the sense that it is easier
and more efficient to edit cross referenced objects (RT objects) at the same time. The copy and paste feature help a lot.

Find-and-replace is a powerful tool to change repetitive data.

It also validates the conformance against the DICOM standard of the latest revision and pinpoints the problems if there were any. In figure 6, one tag (300A,0002) is red flagged because the data length of 46 bytes has exceeded the maximum (16 bytes). The help message tells you the brief description the tag at your cursor position. This is a handy tool for serious DICOM users. I need it myself.

Figure 8 The DICOM editor.

• Anonymize DICOM Objects

As stated in the editor section, all tags in individual DICOM files can be modified, so can be patient’s name tag and ID tag. But when there are many DICOM files to be anonymized, DICOMan provides the user with a specific tool to anonymize all relevant DICOM files of one patient in a single job session.

• Change Patient’s Position

It happens that patient’s position was entered wrong or the patient needs to treated at a different position. This feature can change the position tag for the entire series. The patient does not have to be rescanned. Technically one can change the original position to anyone of other 7 positions because the DICOM standard uses patient-based coordinate system.

Please keep this in mind that it only helps you break the communication barrier not applying any corrections to the anatomical changes in the image study due to the gravity and the position change.

• Convert Image Formats

Many imaging applications in either clinics or research laboratories do not support DICOM format or need extra capital investment for DICOM interfacing module to read images. This format converter will take care of the image format hustle in a few clicks.

DICOM image is treated as one kind of image formats along with common image formats such as BMP, JPEG and TIFF etc. Format conversion between any two of ten is available.

A dedicated feature to read/view multi-framed XRD-FG X-ray image sequence and convert it into multiple image files in either one of ten formats stated above. Here listed are a few examples.

Create Virtual DICOM Phantom

Convert multiple non-DICOM images to a DICOM series. It is particular useful for users who want to create artificial DICOM image phantom from non-DICOM images. Here are a few steps to make your own DICOM image phantom:

1. Paint a series of phantom slices in common image editor such as Microsoft Paint (Figure 8);
2. Name your images in ascending alphabetic order and pay attention to colors for your structures;
3. Read those images in DICOMan and convert them into DICOM images. For details, you are referred to online user’s guide.
4. Read converted DICOM image phantom to verify data conversion (Figure 9).

Figure 9 A sample BITMAP image of a virtual phantom slice.

Figure 10 Verify the converted virtual phantom.

Generate AVI Movie

AVI is a common movie format. It is very well supported in the computer world. When a imaging study of multiple slices is converted to an AVI movie, it can be viewed on any computer or included in a presentation. To download a sample DICOM movie, please click on Figure 10.

Figure 11 A sample CT scan movie viewed in Windows Media Player.

Create Phantom Data for Monte Carlo Simulation Code EGS4

This module is designed to export DICOM objects including imaging series and DICOM RT structure set in EGS4 phantom format. EGS4 is software package for Monte Carlo simulation. This function is a result of inter-institutional collaboration with Yale University. The interested users are referred to Department of Therapeutic Radiology Yale University School of Medicine for Monte Carlo simulation codes.

Figure 12 A sample of EGS4 phantom attributes.

• Fully support DICOM RT objects (RT Image, RT Structure Set, RT Dose, RT Plan, RT Record)

DICOMan is designed for medical imaging users with an emphasis on Radiation Oncology. DICOM RT objects are supported. Here are a few snapshots of RT object rendering.

Figure 13 DVH data rendering. DVH can be switched in mouse wheel and DVH values can be viewed interactively.

Figure 14 Compensator data rendering.

Figure 15 Isodose setting and rendering.

Figure 16 RT Record property sheet in image window.

Figure 17 IMRT fluence in the making (AVI movie).

• RT Dose Summation

Multi-modality dose summation is often needed for patients who have been previously treated or are being treated in different modalities, but unfortunately it is not always available in commercial treatment planning systems. DICOMan will help you sums up 3D dose distributions delivered by different treatment modalities to help radiation therapy team make optimal plans. It can be done either within DICOMan or in conjunction with commercial treatment planning system (Pinnacle³ RTP).

DICOMan also sums up dose matrices of multiple plans to facilitate reviewing treatment plans offline.

Figure 18 Plan dose summation. This is one example of 6 beam dose summation.

Installation Steps

DICOMan 2.2x is recompiled in Microsoft Visual Studio 2005with service pack one. Microsoft So it needs two redistribution packages and a dynamic link library for DirectX that can be downloaded from Microsoft. The user is advised to follow the following installation steps to make it work.

1. Download the needed runtime packages:
   • Microsoft DirectX End-User Runtimes (March 2008 or later)
     directx_mar2008_redist.exe.
   • Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package MFC Security Update vcredist_x86.EXE.
2. Execute directx_Mar2008_redist.exe to unpack installation files to a temporary folder (there should be 88 files) and execute DXSETUP.exe.
3. Execute vcredist_x86.exe. For some reason, the installation order matters. vcredist_x86.exe should be executed AFTER DXSETUP.exe.
4. Create a directory as the home directory for DICOMan, “C:DICOMan” for instance.
5. Download DICOMan software package here DICOMan_package.exe and put it in DICOMan home directory. Since DICOMan is constantly evolving, the users are advised to check our website periodically and have your systems upgraded in the latest version.
6. Execute the self-extracting software package “DICOMan_package.exe” in the home directory of DICOMan. If you are upgrading it, please execute it in any other folder and copy files and “config” folder back to its home directory.

7. Double click the executable “DICOMan.exe” and follow the prompts to get a license.

There are two kinds of licenses as follows,

1. Permanent license. That is what we strongly recommended. The user is provided with full unleashed functions plus free life upgrades.

2. Temporary license. It is time-limited license (about one week). DICOMan functions almost the same as the permanently licensed version as long as the license stays valid. Anyone who is interested in this product can request a time-limited license. Limited number of free permanent licenses are to be issued to whoever are interested in R&D collaboration.

How to Get a Demo License

To get a demo license, the user is advised to install DICOMan following “Installation Steps” posted above and then execute “DICOMan.exe” to generate a computer-specific license request file, “BeerLicense.req”, and attach that file in the email to Yulong.Yan@utsouthwestern.edu. In the email you should also include a brief introduction about yourself, your facility and what use DICOMan for. Should you have any questions, please feel free to contact us as follows.

The best free software solutions for DICOM images

Sometimes it's useful to be able to view and manipulate medical images such as X-rays, CT or MRI scans on your own PC, laptop or tablet. This is particularly important when preparing teaching files or practising for your radiology exams. Finding a good free DICOM viewer can be tricky, especially as there are so many options out there. We have tested may different applications (so you don't have to) and the following are our best picks. We grouped them according to the operating system used because unfortunately there aren't any free viewers that run on both!

A popular software for radiologists working in the UK is currently a programme called 'Horos'. This is a free open source version of the software used by the Royal College of Radiologists for the viva part of the Final FRCR 2B exam, so obviously it makes sense to use it for teaching as well. This programme is only available on Apple computers, hence why so many radiologists own MacBooks.

There is a paid version of Horos called 'OsiriX MD', which is produced by Pixmeo, however it is expensive so not ideal for basic teaching purposes, although has great functionality. Pixemo also produce a free demo version called 'OsiriX Lite', however there are major limitations placed on this including pop-ups asking you to upgrade to the paid version, performance restrictions, image viewing restrictions and inability to edit the meta-data attached to DICOM images - for example you can't easily re-order series within a study, which may be important if you are preparing cases for teaching or examinations. It is for these reasons that we do not list OsiriX Lite in our recommendations.

• The OsiriX UK user group are a group of Radiologists in the UK who are keen on digital radiology education and use OsiriX/Horos for teaching. The aim is to achieve a nationally agreed consensus on how cases are collected, organised and used for teaching and examination and thereby achieve a collective common ground/platform/standard for radiology education across the country. The resources on this site are amazing so we recommend you visit it now!

Why we like it

We really like Horos as it is a free open source version of the same software as that used by The Royal College of Radiologists for the viva part of the final FRCR (Part B) exam. Becoming familiar with Horos will help radiology trainees when preparing for this exam. Horos is easy to use and as a full 64-bit medical image viewer for Mac there is a huge amount of functionality contained within. It is updated regularly. We believe Horos is the best free DICOM viewer for Apple MacOS.

Interestingly, Horos is named after the Egyptian god Horus, son of Osiris and Isis. Horos is a based on OsiriX (a similar paid-for medical viewer), named after Osiris. The developers obviously appreciate Egyptian and greek mythology!
