Problem with Sample CT scan simulation with a voxelized human phantom.

[GoogleCodeExporter]

Hallo,

I have installed debain wheezy 7.0. I would like run  the SAMPLE SIMULATION FOR 
MC-GPU v1.3 USING THE ZUBAL PHANTOM. The voxelizied geometery of the Zubal 
phatnow has been downloaded from the adress http://noodle.med.yale.edu/zubal/.

 The MCGPU was obtained with the command:
 gcc -O3 zubal2mcgpu.c -o zubal2mcgpu.x 

The exceution of the next command showed an error  Memory access erorr

./zubal2mcgpu.x zubal2mcgpu_conversion_table.in voxel_man.dat

The used System for the MCGPU has the following specfications:  

-Processor

Intel® Pentium® 4 Processor 641   • 3.20 GHz, 2 MB L2 cache, 800 MHz front 
side bus 

- Standard memory 

512 MB (256 MB x 2)

- Graphic Subsystem Video Card Memory

Graphics memory is shared with system memory. Graphics memory usage can vary 
from 8 to 128 MB depending on the amount of system memory installed and system 
load

Thank you

Regards 
Ghassan
