<p>In an intra oral dental X-ray system, a solid state imager 1 includes an array of CMOS pixel circuits 6 and has a fibre optic taper 5 located between the array 6 and scintillator material 4. During use, X-ray radiation transmitted via an object 2 to be imaged from a source 3 and is incident on the scintillator material 4 where it is converted into light. The light is transmitted via the taper 5 to the array 6 where an image is generated which is representative of the radiation transmitted through the object 2. The fibre optic taper 5 provides good image quality and maintains resolution. <IMAGE></p> |
