[Gate-users] GATE- Reading CT output

[Mahdjoub Hamdi]

Hello Chaitanya,

 

 Yes I’m able to read the 2D projections obtained by CT output. The binary
files ‘benchmarkCT_000.dat’ and benchmarkCT_001.dat are written in ‘float 32
bit’, if you have Matlab you can read it easly by:

 

fid = fopen(‘benchmarkCT_001.dat’, 'r');

2dProj = fread(fid, [100 100], 'float32');   %  [100 100] is the matrix size
of your CT detector.

fclose(fid);

 

figure, imagesc(2dProj), colormap(‘gray’),  colorbar

 

 If you don’t have Matlab you can use the free open source ImageJ
http://rsb.info.nih.gov/ij/ .

 

Bests,

 

Mahdjoub Hamdi.

Hi Mahdjoub,

 

I'm Chaitanya, a graduate student at IIT Madras, India. I've been trying to
use GATE recently to simulate a CT scanner.

 

I was going through the gate mailing lists on how to use the output from the
CT simulation (3 files - benchmarkCT.root, benchmarkCT_000.dat,
benchmarkCT_001.dat). 

 

I just wanted to know if you wer able to solve this problem you posted a
year ago.

Also, were you able to visualize the projections as in pages 2 and 3 in the
attached document?

 

Thank you very much for your time. Looking forward to your reply.


Thanks,
Chaitanya Kolluru
