Overview of Technologies

Abstract

Indirect imaging systems such as SPECT have three essential components: an image-forming element, an image detector, and a reconstruction algorithm. These components act together to transfer information about the object to the end user or observer, which can be a human or a computer algorithm. As we shall see in Chapter 5, the efficacy of this information transfer can be quantified and used as a figure or merit for the overall imaging system or for any component of it. Fundamentally, image quality is defined by the ability of some observer to perform some task of medical or scientific interest.
