Acquisition of Medical Image Data

Abstract

This chapter provides an introduction into the most essential medical image acquisition processes with a focus on tomographic 3D image data. As a prerequisite sampling processes and interpolation is explained. We briefly discuss major requirements that guide the selection of imaging modalities in practice, e.g., to provide a sufficient spatial resolution for the diagnostic question, to limit the exposure to radiation and to achieve a sufficient image quality in terms of contrast and signal-to-noise ratio (SNR). Readers should understand that trade-offs between these conflicting goals are necessary. Thus, neither optimum spatial resolution nor optimum image quality are relevant goals in clinical ...
