Hi all,
I am working on Cone beam images.
Is there any way in Matlab to open the cone beam projections (raw data) that are saved as .hnd file formats.
Because the matlab do not support opening .hnd files, I really want to know the way to do it.
Please help me.

I do not yet see any method at the moment of opening the Varian HND files in MATLAB.
I find them handled in this (non-MATLAB) tool: http://plastimatch.org/index.html.
I also find a reference that says the Varian file format is described well in their User Programming Guide.
I noticed a File Exchange contribution that might perhaps be useful in your work once you have the data read in: http://www.mathworks.com/matlabcentral/fileexchange/6032-iconebeam . And perhaps also http://www.mathworks.com/matlabcentral/fileexchange/23314-multithreaded-mex-fdk-conebeam-ct-reconstruction-algorithm or http://www.mathworks.com/matlabcentral/fileexchange/30207-cone-beam-ct-simulation. Oh, and http://www.cs.toronto.edu/~nrezvani/OSCaR.html

Hello,
I was just looking on the internet for code to read varian .hnd files and i found a recently added toolbox which works well for me so far. Unfortunately for some it is configured for windows only. link to download: https://bitbucket.org/dmoderesearchtools/ximreader/downloads/
It was written by Andre Meyers (THANK YOU!) and says it's copyright is owned by varian medical systems so seems legit. i hope this helps.
