To celebrate Professor Hengyong Yu's elevation to IEEE fellow, the IEEE student chapter at UMass Lowell invited Prof. Yu to give a presentation on medical imaging on Feb. 27, 12:30 p.m. in Ball Hall 214.
In this presentation, Prof. Yu will first give an overview of X-ray imaging, including the invention of X-ray and CT scanner, and how it works. Then, he will focus on the development of the interior tomography theories and algorithms, as well as the state of the art and the challenges. He will also talk about his ongoing projects on AI-based Cardiac CT and Photon-counting CT. Many interesting images on biomedical applications are included in the presentation.
Highlights include:
- The original idea of CT, a simple example of reconstructing a map from two pictures
- The invention of X-ray and CT scanner and the basic of a CT scanner
- State of the art multi-slice CT
- CT reconstruction basics: Direct Fourier reconstruction, Filtered Backprojection
- Interior Problem, multi-source cardiac-CT, nano-CT
- Exact knowledge-based method, and its application to lung CT
- Exact local reconstruction via total variation minimization, and its application to cardiac CT
- Modality Extension, Interior SPECT/PET; Interior-MRI; Color Interior Tomography; Omni-Tomography
- Funding and projects: AI-based Cardiac CT ($3.13M); Unsupervised Deep PCCT Reconstruction for Human Extremity Imaging ($2.92M)
- New course: Introduction to Medical Image Reconstruction (EECE.4300/5300)
