MIPG Lab at Penn Medicine: Segmentation of representative organs in thorax and abdomen from CT images.

Segmentation of representative organs in thorax and abdomen from CT images.



The Medical Image Processing Group (MIPG) at Penn Radiology is one of the oldest and longest active leading research groups in the world engaged in research on the processing, visualization, and analysis of medical images and the medical and clinical applications of these computerized methods.

Some areas of current research study include body-wide Automatic Anatomy Recognition (AAR), body-wide disease quantification (DQ), body composition assessment, radiation therapy planning, pre-treatment planning in thoracic insufficiency syndrome (TIS), and study of obstructive sleep apnea via dynamic MRI.
