This is important for my research because
it manages the large amount of images that I acquire into a simplified program
for radiologist to view. This program also views images randomly so no
radiologist can see them in the same order this results in objectiveness in
diagnosis and more accuracy. Not mentioning that there will be no need for
papers as the program provides criteria on the side of each image group (Green
planet friendly). I recommend this program for image based research because it
is a time saver and a good way to catalogue findings specifically in MR
imaging.

Hi Muna,
I am Henry from the University of Queensland, and I'm looking to use ViewDex in a study comparing CT scans to digital tomosynthesis scans. When using ViewDex, I'd like radiologists to be able to measure items on the scans and enter in the exact distance as a response to be recorded by ViewDex. However, it appears that ViewDex only supports discrete checkboxes for recording responses. As you have good experience with using ViewDex, I was wondering if you knew of any way to enable the recording of continous data as a response in ViewDex?
Thanks very much for your time,
Henry
Hi Henry,
Thank you for reading my post, to answer your query:
I believe that viewdex is design to facilitate easy VGA of a large group of images, by that i think mostly scaling and rating. the program does allow simple image manipulations to be done (ww/wL, zoom ect). I cannot say if measurements are possible, however, you can contact the main site am sure they will help you more. for my research i used the program for image rating, all my measurements were done on a viewer like (DICOM, OSIRIX, EMV). viewdex is java based and i think it needs a little computer know how to manipulate.
i hope this helped.
kind regards,
Muna
am sure you have read this but am adding an abstract, From DOI: 10.1117/12.811511 :
ViewDEX is managed and configured by editing property files, which are plain text files where users, tasks (questions, definitions, etc.) and functionality (WW/WL, PAN, ZOOM, etc.) are defined. ViewDEX reads all common DICOM image formats and the images can be stored in any location connected to the computer. ViewDEX 2.0 is designed so that the user in a simple way can alter if the questions presented to the observers are related to localization or not, enabling e.g. free-response ROC, standard ROC and visual grading studies, as well as combinations of these, to be conducted in a fast and efficient way. The software can also be used for bench marking and for educational purpose
