1 – Real Time 4DCT treatment [UT Southwestern medical center, TX, USA ]
Duration: Jan 2016- in progress Team Size: 4

Role Played: Developer and Tester Skills Used: C++, CUDA, machine learning, python, matlab and MySQL.

This project uses the images generated from 4DCT treatment to compare with the projections that generated by digital reconstruction of radiograph (KV and MV) with Monte Carlo simulation. Then decide which phase is the patient, and adjust the treatment plan in real-time.

2 – Interactive IMRT planning [UTSW, TX, USA]
Duration: Nov 2015 - Feb. 2016 Team Size: 2

Role Played: Designer, Developer and Tester Skills Used: C++, VTX, wxWidget

The Intensity Modulated Radiation Therapy (IMRT) planning is very difficult. The IMRT planning uses a subset of patient’s voxels that interested by physician/clinician, and give a real-time planning with visualized dose distribution. It is called as Physician-driven Planning Treatment system.

3 – GPU-based discrete wavelet transformation [UTSW, TX, USA]
Duration: Oct 2015 Team Size: 2

Role Played: Designer, Developer and Tester Skills Used: C++, CUDA

It was a small project to develop a GPU/CUDA based discrete wavelet transformation (DWT) and inverse discrete wavelet transformation (IDWT) codes, and apply it to the high performance CT image processing. The optimal GPU/CUDA codes can significantly speedup 2-D and 3-D DWT and IDWT, e.g., in a test with 512×512×256 images data in single precision, we can obtain a 57x fold speedup.
