Abstract
An extra-oral digital panoramic dental x-ray imaging system for multi-layer panoramic and transverse X-ray imaging providing with an X-ray source and a digital imaging device providing real time frame mode output and autofocusing. The X-ray source and imaging device are mounted in a mechanical manipulator defining the trajectory of a predetermined image layer. The imaging device communicates with a processor that generates a frames memory from which an image reconstruction mechanism composes the final images.
Claims29
An extra-oral dental x-ray imaging system comprising:
- a. an x-ray source adapted for generating x-rays for an exposure of such x-rays to an object to be imaged;
- b. a frame mode x-ray imaging device adapted to produce multiple frames during at least part of the exposure;
- c. at least one rotational axis around which at least one of the x-ray source and the imaging device rotates along a spline, the axis being located somewhere between the x-ray source focal point and the x-ray imaging device;
- d. a manipulator adapted for moving said at least one of the imaging device and the x-ray source between the multiple frames during the exposure about the at least one rotational axis;
- and
- e. a processing device for taking inputs of the multiple frames to compose a panoramic image of a layer of the object with a focus depth which is different in a region of interest from a focus depth corresponding to a predetermined panoramic image, wherein the focus depth for the region of interest is determined automatically.
An extra-oral dental panoramic X-ray imaging system comprising:
- a. an x-ray source adapted for generating x-rays for exposure of such x-rays to an object to be imaged;
- b. a frame mode x-ray imaging device adapted for producing multiple frames at a rate of at least 30 frames per second during at least part of the exposure;
- c. at least one rotational axis around which at least one of the x-ray source and imaging device rotates along a spline, the axis being located between the x-ray source focal point and the x-ray imaging device;
- and
- d. a storage system capable of storing the radiated frames, produced by said imaging device, in real time;
- said storage system storing radiated frames with a time delay of not more than one second.
