An x-ray detector includes a scintillator that converts an invisible-radiant-energy image into a visible-light image and a sensor array that converts the visible-light image into an electrical signal. The sensor array comprises a plurality of CMOS active pixel sensors.

Method for reading out data from an x-ray detector

A method and apparatus for producing a X-ray image of a patient's teeth by placing an intra-oral sensor having a plurality of pixels disposed in a linear array inside the patient's mouth, and moving a radiation source around outside of the patient's mouth. The intra-oral sensor detects the radiation that has passed through the patient's teeth and generates corresponding output signals that depend on the amount of radiation arriving at each pixel. The information contained in the output signals is stored and can be used to create an X-ray image of the patient's teeth. The intra-oral sensor can be moved about inside the patient's mouth in coordination with the movement of the radiation source in order to improve the resulting image quality. This method and apparatus can be used to obtain an X-ray image of any number of teeth, including a panoramic image of all of the patient's teeth, in a single, quick, uninterrupted operation.

X-ray detection system using active pixel sensors

AA method and apparatus for measuring bone density using x-ray radiation at two energy levels, and an image sensor array that comprises a plurality of CMOS active pixel sensors.

Apparatus for measuring bone density using active pixel sensors

A large area image detecting apparatus made by arranging a plurality of small area sensors in a stepped arrangement so that the inactive regions of the small sensors are covered by a active area of another small sensor. The apparatus may be used to detect light or radiation. A fiber optic assembly may be used to guide light from a flat scintillator plate onto the small sensors.
