"Principles of PET" (textbook)

"Principles of PET" refer to the fundamental concepts behind Positron Emission Tomography, a medical imaging technique. PET works by injecting a small amount of radioactive material into the body, which emits positrons as it decays. When these positrons collide with electrons, they produce gamma rays that are detected by the scanner. This process creates detailed images of metabolic activity and blood flow within tissues, helping diagnose and monitor diseases like cancer and neurological disorders. The principles involve understanding how radioactive tracers behave, the detection of gamma rays, and the reconstruction of images to visualize physiological processes in the body.
