Abstract
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.
