How to open extension .a00 and .sin image Using Matlab

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?

file as attached.

Both file I was open using ImageJ. (The picture as attached). But I dont know how to open using matlab.

point2 using ImageJ

YourProjection (1) Using ImageJ

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');
fclose(fid);

A = reshape(A,512,[]).';

imshow(A,[])

fid = fopen('point2.a00','r');
A = fread(fid,Inf,'*uint16');
fclose(fid);

A = permute(reshape(A,512,512,[]),[2 1 3]); % there are 8 pages

imshow(A(:,:,1),[])

TQ very much sir. Its Work. But how to open the file with .hdr extension sir? file as attached.

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:
