Principles of Medical Imaging
MIT OpenCourseWare offers this introduction to tomographic imaging, covering both ionizing and non-ionizing modalities including x-ray, PET, MRI, and ultrasound. The course pairs a series of lectures with parallel recitations that demonstrate the underlying physics and engineering of image formation, from signal acquisition to reconstruction. Topics include radiation interaction with tissue, detector design, and the mathematical methods used to turn raw signals into diagnostic images. Materials include lecture notes, recitation problems, and assignments drawn from MIT's Nuclear Science and Engineering curriculum. The course suits students with a background in physics or engineering who want to understand how modern scanners actually produce the pictures radiologists read, treating imaging as an applied physics problem rather than a clinical one.
