Last update : October 20, 2016
Note : the new versions released since spring 2016 have not yet been tested. It will be done in the coming days.
This contribution refers to my recent updated post about DICOM image viewers. Mobile DICOM viewers are becoming more and more popular. They are very useful in the context of medical applications in the cloud.
Most web viewers can be used on mobile equipments (tablets, smart phones, …), but the focus of this post are native applications designed for Apple iOS or Android devices. DICOM Web viewers are handled in a separate contribution. In the present list I considered only those applications that have been updated after January 2014, with some exceptions.
To test the selected apps, I used Orthanc (Windows versions 0.9.5 and 0.9.6) as PACS server. To have realistic DICOM samples, I uploaded some DICOM studies from me and from family members relative to exams done in the past in hospitals in Luxembourg and France.
To set up a communication between a DICOM viewer and the Orthanc server, the viewer should allow to define the following parameters in the settings :
- Remote AET
- Remote Hostname/IP
- Remote port number
- Local AET
- Local port number
- Protocol : C-MOVE
The local IP is the address of the used mobile device.
If no settings are available for the port numbers, the port number of the server can be added to the remote IP address. The standard port number 104 can be tried as a first guess for the settings of the viewer. If no local AET settings are provided, the iPad name can be tried as a first guess. Another possibility is to use a DICOM network analyser like DVTk to detect unknown parameters. If the C-MOVE protocol is not supported by the viewer, the WADO or C-GET protocols can be an alternative.
In the presentation of the selected mobile viewers, I generally used the terminology published by the developers, even if I disagree with their claims. In the case of apps that worked as expected with the Orthanc server, I added some screenshots to show the look-and-feeling of the viewer.
Purpose of the evaluation
You may ask what is the purpose to evaluate proprietary closed source applications in an open source environment. I started the evaluation in mid-2015 in the context of the development of an educational tool for radiologists, called RadioLogic. The reasons were various :
- to familiarize with the DICOM technologies (learning by doing)
- to compare the performance of native apps with HTML5 web apps on tablets and phones
- to explore the different types of graphical user interfaces to create a best-of-breed GUI for the RadioLogic project
- to examine the assets of viewers certified / cleared by FDA or CE
- to test features that are not (yet) available on HTML5 web apps
The following DICOM viewer apps, which are currently available at the AppStore, have been tested. They are arranged and listed in alphabetical order :

Among the 29 tested native mobile DICOM viewers, 18 are iOS apps, 6 are Android apps and 5 are available on the two platforms. 9 viewers can be configured to access a vendor-neutral PACS server, but only 5 of them work as expected and comply with the Orthanc PACS server. Among them are the three renowned commercial viewers iMango, iTA View and Osirix (priced between 15 and 50 USD), one free app (iPaxera) developed by a world leading medical imaging solution provider (Paxeramed Corp) and one app (DICOM IR) created by an independent free-lance developer ( Pietro Zuco). The other 4 configurable viewers are limited, partially disabled or crashing.
The remaining viewers are demo apps working with proprietary PACS systems, displaying only DICOM files loaded from DropBox or from another web server or crashing and working not at all. There are additional DICOM viewer apps in the AppStore and the Google PlayStore which are not listed because they were not updated in the last two years.
My two cents
I was shocked to see that most native mobile apps in the medical domain are not state of art. Apps in the stores which have not been updated in the last few years, text errors in the menus, program errors in the logic ( 2 viewers change the AETitle during communications), crippled GUI’s when the orientation of the device changes, wrong version numbers in the about panel etc, are testimonies of the poor quality.
