This section covers a number of general concepts applicable to all the imaging modalities in this book. 1 Spatial Resolution There are a number of measures used to describe the spatial resolution of an imaging modality. We focus on describing a point spread function (PSF) concept and show how to use it to analyze resolution limitation in several practical imaging schemes. Point Spread Function Consider an idealized object consisting of a single point. It is likely that the image we obtain from it is a blurred point.

Var[ξ] is called the standard deviation, which is a measure of the average deviation from the mean. The PDF of measurement noise is not always known in practical situations. We often use parameters such as mean and variance to describe it. In fact, based on the central limit theorem, most measurement noise can be treated as Gaussian noise, in which case the PDF is uniquely defined by its mean and variance. Recall here the central limit theorem: When a function h(x) is convolved with itself n times, in the limit n → +∞, the convolution product 38 2 Preliminaries is a Gaussian function with a variance that is n times the variance of h(x), provided the area, mean, and variance of h(x) are finite.
