This session will delve into X-ray radiography and computed tomography (CT). This includes subject density and X-ray attenuation; Half Value Layer (HVL), beam hardening, magnification and blurring; screen-film Radiography (SFR) characteristic curves, optical density, speed and film sensitivity; digital radiography which includes photo-stimulable phosphor screens and digital thin-film-transistor liquid-crystal display flat panel detectors, dose creep; specialised imaging modes, namely fluoroscopy and mammography; and computed tomography scans, including methodology, scan geometry, detector setup, multislice helical CT, Hounsfiled units and image reconstruction.
