[Rtk-users] reconstruction by cuda occur problem: ITK ERROR: CUDA ERROR: out of memory

[......]

Hello all,
I tried reconstruction my projection data by cudaFDK, and my data is 360*3008*2048 with type uint16. I set my output volumn size as 752*752*624. When I run my code with GPU(GeForce RTX 4090), there appear the error:
 

I checked the code execution process and during this period, the GPU's memory was still very sufficient. I reduce the size of my data to 360*1504*1024 and other items remain unchanged. This  code can run without error.
The attachment is my code. Any help will be appreciated.
Sincerely,


......
