Chapter 1 discusses the discovery of X-rays over 100 years ago, and how Computed tomography proved to be much more than an incremental advance over simple X-ray tomography because it both improved tissue contrast and, for the first time, allowed imagers to see the patient in cross-section. It goes on to cover axial versus helical imaging, multiple detector row CT, CT image contrast, slice thickness, isotropic voxels and reconstructions, cone beam imaging, iterative reconstruction, Gantry angulation and image display, and scan speed.
