Indirect sensors are photostimulable phosphor
(PSP) plates, which resemble radiographic film, and which must be "read" by a scanner that in turn transfers the "interpreted" information to the computer.
Much digital growth has been fueled by a transition by many to the less expensive CR C the technology of making x-ray images with conventional x-ray equipment but in which the images are captured on reusable photostimulable phosphor
plates, instead of single-use x-ray film.
The dental X-ray system market, comprising intraoral and extraoral X-ray systems, is growing primarily due to the increasing adoption of photostimulable phosphor
(PSP) plate systems and digital X-ray sensors.
