This open access book gives a complete and comprehensive introduction to the fields of medical
imaging systems as designed for a broad range of applications. The authors of the book first
explain the foundations of system theory and image processing before highlighting several
modalities in a dedicated chapter. The initial focus is on modalities that are closely related
to traditional camera systems such as endoscopy and microscopy. This is followed by more
complex image formation processes: magnetic resonance imaging X-ray projection imaging
computed tomography X-ray phase-contrast imaging nuclear imaging ultrasound and optical
coherence tomography.
