Hi all,
I have generate image from GEANT4 Monte Carlo simulation.
the file extension is .sin (as attached zip file: YourProjection (1))
I also generate image from SIMIND Monte Carlo simulation.
the file extension is .a00 (as attached zip file: point2)
Anyone know how to open it using matlab?

It seems the files are binary files. You need to use fread to read the data. But you need to know the format of the file.

Like KSSV says, use fread()
fid = fopen('YourProjection (1).sin','r');
A = fread(fid,Inf,'*uint16');
A = reshape(A,512,[]).';
fid = fopen('point2.a00','r');
A = fread(fid,Inf,'*uint16');
A = permute(reshape(A,512,512,[]),[2 1 3]); % there are 8 pages

You need both the header file (HDR) and the image file (IMG). The HDR file contains no image data. You should be able to use the interfile reading tools:
