Martin Caon Examination Questions and Answers in Basic Anatomy and Physiology Third Edition Chapter 17: Ionising Radiation 17.1 Medical Imaging with X-Radiation X-ray photons directed at a patient do one of three things: 1. Pass straight through the patient (who is mostly empty space) without deviating from their trajectory, to strike the detector and form the medical image. 2. Are stopped within the patient by ionising some of the patient’s atoms, leaving their energy in the pat...
