Radiotracers are chemical compounds that are used to diagnose or deliver therapy to specific organs and tissues. The radiotracer consists of a linking molecule, a binding molecule and a radioactive compound. Radiotracer is injected into the body and it binds to specific target cells in the body. The linking molecule binds the radioactive compound to the binding molecule, which then binds to specific cells in body.
The radiotracer decays by emitting ionizing radiation that damages nuclear DNA, thereby stopping division of cells (cancer as well as normal cells). Radiotracers are not something new. In fact, they have been around for 100 years !!
The effect of radiation transport and quantum noise on image quality is explored in the context of both conventional and newly developed systems. Radiation sources for imaging, mathematical descriptions of image quality, and the performance of humans as visual observers are covered. Specific systems considered include phosphor screen and direct digital radiography systems, Anger camera systems, x-ray computed tomography (CT) systems, and Positron Emission Tomography (PET) systems. Particular emphasis is given to the statistical processes important in radiographic and nuclear medicine imaging systems.
