Tissue characterization is a research area focused on studying and identifying the properties and composition of various types of tissues in the body. This field of research uses various imaging techniques, such as MRI, CT scans, and ultrasound, to analyze the structure, function, and behavior of tissues at a cellular and molecular level. The goal of tissue characterization is to better understand normal and diseased tissues, identify biomarkers for disease detection and monitoring, and develop new diagnostic and therapeutic approaches for various medical conditions. This research area is interdisciplinary, involving expertise in biology, medicine, engineering, physics, and computer science.
