In this research topic, we are working on developing state-of-the-art machine learning-based imaging and image restoration techniques for clinical applications in Radiation Therapy (RT) and diagnosis. Notably, RT heavily relies on multi-modality imaging for optimal cancer patient treatment. Medical imaging plays a critical role in every step of the RT workflow, including from patient staging, tumor target and organ-at-risk delineation, radiation treatment planning, treatment plan delivery, and treatment response assessment. We have developed novel image restoration and processing algorithms to improve clinical practice in RT and disease diagnosis, which include organ-at-risk contouring error detection, tumor delineation, internal organ motion tracking, and metal artifact reduction in CT images, 3D blood vessel segmentation, and brain tissue segmentation. In addition, we have conducted novel medical imaging and image processing methods to solve the problems outside the clinical imaging field, such as automatic cell counting in microscope images.
