# Medical Imaging

> Medical imaging develops technologies to visualize anatomy, physiology, and molecular processes inside the human body with minimal invasiveness. Photon-counting CT detectors provide spectral information at every pixel, enabling material decomposition and radiation dose reduction simultaneously. Ultra-high-field 7T MRI scanners resolve cortical layers and individual hippocampal subfields relevant to Alzheimer's disease and psychiatric disorders. PET tracers labeled with short-lived radioisotopes map receptor binding, metabolic activity, and amyloid plaque burden in vivo. Deep learning image reconstruction algorithms reduce scan times and noise while preserving diagnostic information. Medical imaging is undergoing AI-driven transformation, with automated detection of fractures, tumors, and vascular disease matching radiologist accuracy in controlled settings.
