Radiographic TechniqueCâu 55 / 100
An office uses photostimulable phosphor (PSP) plates. A faint image from the previous patient appears on a new radiograph. What was omitted?
a.The plate was not sterilized in the autoclave
b.The plate was not soaked in disinfectant for ten minutes
c.The plate was not exposed at a higher kVp
d.The plate was not erased with the light source after scanning before being reused
Giải thích
PSP plates retain latent image data until they are erased by exposure to a bright light source, so skipping the erasure step leaves a ghost of the previous image on the next radiograph. Autoclaving and prolonged soaking would destroy the plate; PSP plates are barrier-protected and disinfected according to the manufacturer's instructions instead. Raising kVp changes beam energy and does not remove residual image data.
