Abstract
An imaging system for producing a panoramic radiograph of a patient's jaw for dental analysis includes an X-ray source (2) carried at one end of an arm (1) and detector means (7) at the other end. The front surface of the detector means (7) carries scintillator material (8) which substantially solely defines the area of the detector means at which the image information is captured. The secondary diaphragm or slot used in conventional panoramic X-ray imaging systems can thus be omitted, giving a less complicated system.
Claims8
An imaging system for dental use comprising:
- a source of X-ray radiation;
- solid state detector means having a radiation sensitive region which includes an image area at which charge accumulates which is representative of incident radiation;- scintillator material carried on the surface of said image area for converting X-ray radiation into radiation of a different wave length for detection by said detector means, there being no secondary diaphragm or slot serving as an aperture in said system to define said image area;
- means for moving said source and said detector means relative to a subject to be examined, in which the subject is arranged to be located between them;
- and means for processing the output of said detector means to obtain a panoramic image of the subject.
