Abstract
Most of imaging modalities in medical science map some spectroscopic property of object onto sensor. The electromagnetic radiations have widely been used for this purpose, and the corresponding imaging modalities use emission, absorption, scattering, or reflection of these radiations. The X-ray radiography, positron emission tomography, fluorescence imaging, and magnetic resonance imaging (MRI) are few examples of the electromagnetic imaging. The electromagnetic spectrum covers a wide range of wavelengths and frequencies as shown in Fig. 6.1.
