Medical imaging
The document provides an introduction to various medical imaging modalities such as x-ray, CT, nuclear medicine, ultrasound, and MRI. It describes how each modality works by generating images using different physical principles such as x-ray transmission, radioactive decay, acoustic reflection, or magnetic resonance. The modalities can be used to non-invasively visualize internal organs and tissues to diagnose and evaluate conditions like cancer, stroke, neurological disorders, joint issues, and lung abnormalities.
