[Gate-users] output CT with extension .dat

[강한규]

Dear Hassan,
 
The CT projection output file is binary and data type is float32.
 
Thus, you can read the CT projection output file by using the following command in MATLAB.
-----------------------------------------------------------------------------
fname = 'benchmarkCT_001.dat'
NumOfPix_Y = 100;
NumOfPix_X = 100;
 
A = fread(fid,[NumOfPix_X NumOfPix_Y],'float32');
-----------------------------------------------------------------------------
Here the matrix size is 100 x 100. But you can use the appropriate matrix size for your GATE simulation.
The 2D matrix (i.e. projection image) is assigned on the variable "A".
 
In order to obtain the sinogram, the projection images for each angle should be merged together as follow.
 

Hopefully, my answer would be helpful for your CT simulation.

Best regards,

Han Gyu Kang

hi Gaters;
after my simulation of CT-scan finished, i get the output  benchmark.dat by this output code :  
############
# CT Image #
############
/gate/output/imageCT/verbose 0
/gate/output/imageCT/enable
/gate/output/imageCT/setFileName output/benchmarkCT

/gate/random/setEngineName MersenneTwister
/gate/output/imageCT/setStartSeed 567489
but i can't open this file output: benchmark.dat ?
any help please ?
and how can i obtain a sinogram as output?
thank you
