MOCUPY is a CT reconstruction software based CUDA for GPU-accelerated, which written by Python and developed by the team of HEPS TXM beamline. MOCUPY contains modules such as Image import, Preprocessing, Shift align, Phase retrieval, Reconstruction and data analysis modules, which can realize the fast reconstruction of offline data. So as to meet the data processing requirements of synchrotron radiation users for "massive" X-ray CT.
- l The core algorithms achieve 100% GPU acceleration. Based on multi-threading to achieve fast reading of data and data processing with IO, CPU and GPU as the same time.
- l Rotation axis correction automatically for multi-scale and ring artifacts removal based on wavelet transform.
- l Provide manual and auto alignment modes for nano-CT images jitter correct, and the image correction accuracy can reach sub-pixel.
- l Realize the phase retrieval of propagation-based X-ray phase-contrast imaging in single ditance and multiple ditances acquisition modes. The main algorithms include tie, ctf, tiehom_Rytov, tiehom_Paganin, hioer, etc. It takes only 3 minutes for phase retrieval of 1022 projections.
- l A variety of reconstruction algorithms such as FBP, Grid and EM are provided. It only takes several seconds for tomographic datasets with image size of 2k*2k to reconstruct based on grid algorithm.

SYSTEM REQUIREMENTS
The algorithm of MOCUPY is based on CUDA Libraries，which requires Turing/Ampere cores or newer NVIDIA graphics/computing cards(https://www.techpowerup.com/gpu-specs/?mfgr=NVIDIA&sort=name).
In addition, in order to achieve higher reconstruction speed, please use the NVMe SSD (such as WD:SN770/SN570、KBG40ZNS) to read and write data.
The recommended computer graphics card performance (or higher) is as follows：
