The Method of Least Squares and Signal Analysis, squares method is one way to accomplish this goal. We use the least squares method to derive how to approximate a function by a sum of oscillating functions: the Fourier series. Fourier analysis is then developed in detail, including aliasing, Fourier transforms, the power spectrum, and the autocor

Images,ribe general properties of all these images. Mathematical tools such as the convolution integral and the two-dimensional Fourier transform are used to analyze an image, and the qualitative appearance of an image is related to its spatial frequency content. One of the central concepts of the chapter

Medical Uses of X-Rays, radiation. We introduce some quantities that are important for measuring how the absorbed photon energy relates to the response of a detector, which might be a film, an ionization chamber, a chemical detector, or a digital detector. Several specialized techniques are described, such as angiography,

Nuclear Physics and Nuclear Medicine,ng different mechanisms of radioactive decay, such as alpha, beta, and gamma decay, internal conversion, electron capture, and positron emission. It is important to know the dose to the patient from a nuclear medicine procedure, and we describe the standard technique for calculating it. Imaging usin
