摘要： A method for obtaining an intraoral x-ray image determines an initial spatial position and angular orientation of an x-ray source relative to a detector. A first x-ray image is obtained with the x-ray source at the initial spatial position and angular orientation and stored, associating the initial spatial position and angular orientation to the first x-ray image. A sequence repeats that calculates a next spatial position and angular orientation for the x-ray source, provides positional adjustment information between the x-ray source and detector for obtaining a next x-ray image, measures and records the actual spatial position and angular orientation of the x-ray source relative to the detector and obtains and stores the next x-ray image at the measured spatial position and angular orientation, and forms a composite image using image data from the first and from the one or more next x-ray images.

摘要： This invention relates to a method to manufacture a chip to detect the direct conversion of X-rays. It also relates to a direct conversion detector for X-rays using such a chip and dental radiology equipment using at least one such detector. The method to manufacture the wafer comprises a step for applying pressure (3, 4, 4 a) to a powdered polycrystalline semiconductor material and a step for heating (5-9) during a set time period. It comprises a preliminary step for providing an impurity level of at least 0.2% in the polycrystalline semiconductor material.

摘要： An apparatus for obtaining an intraoral x-ray image from a patient has an x-ray source and an intraoral image detector comprising one or more detectable elements. One or more sensors are positionally coupled near the x-ray source and are energizable to sense the location of the one or more detectable elements when the intraoral image detector is within the patient's mouth. A control logic processor is in signal communication with the one or more sensors and is responsive to stored instructions for calculating a detector position of the intraoral image detector. A projector is positionally coupled to the x-ray source and is in signal communication with the control logic processor and is energizable to project an image toward the calculated intraoral image detector position in response to signals from the control logic processor.

摘要： A combined imaging apparatus for x-ray imaging of a subject in multiple modes has a supporting structure having an extended rotary arm, wherein the rotary arm has a computed tomography detector and a panoramic imaging detector, both mounted adjacently against a movable platen. A detector positioning apparatus is actuable to translate the position of the movable platen to either of at least first and second positions with respect to an x-ray source. The first position disposes the computed tomography detector in the direct path of an x-ray source and the second position disposes the panoramic imaging detector in the direct path of the x-ray source.

摘要： A dental radiology apparatus includes an X-radiation generator and a sensor opposite it receiving radiation from the generator. The apparatus produces a panoramic image of an object by displacement of the assembly formed of the generator and the sensor along a given trajectory in a plane, the generator having at least one collimation slit elongated along a z-axis perpendicular to the plane to produce an X-ray beam elongated along this axis in a first mode of operation, the sensor with an array of pixels extending along the Z-axis in correspondence with the beam. The apparatus includes elements for pivoting the sensor by 90° to extend it in a direction parallel to the plane P, switching the generator provided with the collimation slit from the first mode to a second mode of operation to produce an X-ray beam elongated parallel to the direction of the sensor, so that the these positioned sensor is always in correspondence with the beam.
