Document Summary
Radiography- the art & science of using radiation to provide images of the tissues , organs , bones , and vessels that comprise the human body. Radiograph - a static image generated following the passage of rays through the patient. Recorded (acquired) using a radiation- sensitive plate that measures the rays transmitted through the patient. It is an illustration (map) of how various patient tissues attenuate the x -radiation . fiance. Ray - primary beam (f) psaetient (object/ part) Tier: ray - strong light but not strong enough for other dense parts of body , attenuation - Interaction or the beam by the part increased attenuation , less receptor exposer no attenuation - appears black in. Ray in agto radiation that - receptor is. Low atomic # more photons reach the _b image receptor w/ low beam attenuation.
