Patent ID: 8705691

Claim:
A dental cone beam computed tomography X-ray apparatus, comprising: an X-ray sensor having an active surface including a first area and a second area; and an X-ray generator simultaneously movable with the sensor in rotation about a rotation axis to emit an X-ray beam toward the sensor, the generator having a collimator collimating the emitting X-ray beam and illuminating the first and second areas of the sensor, the collimated X-ray beam illuminating the first area of the active surface with an intensity greater than the illumination of the second area so as to provide the second area with a X-ray safety function, the sensor oriented such that a longitudinal axis extending from the generator to the sensor and passing through the rotation axis is perpendicular to the active surface of the sensor, a center of the sensor being offset transversely relative to a projection of the axis onto the active surface of the sensor.
