Dental x-ray unit providing a cephalometric image and associated method

摘要

A dental x-ray unit comprising: an X-ray generator adapted to generate an X-ray beam in the direction of a patient's head, means of collimation adapted to confer given dimensions to the generated X-ray beam; a sensor placed facing the generator, receiving the radiologic projection of the collimated beam having irradiated the patient's head and supplying a cephalometric image of the patient's head, characterized in that the device includes: the means to acquire at least one photographic image of the patient's head, the means of automatic control for the means of collimation according to the at least one photographic image so that the dimensions of the collimated X-ray beam are adjusted to the dimensions of the patient's head.

1. A dental cephalometric x-ray unit comprising:
an X-ray generator adapted to generate an X-ray beam in the direction of a patient's head; a means of collimation adapted to provide given dimensions to the generated X-ray beam to generate a collimated X-ray beam; a sensor, disposed facing the generator, receiving the x-ray projection of the collimated beam irradiating the patient's head to generate a cephalometric image of the patient's head; means to acquire at least one photographic image of the patient's head; and means of automatic control of the means of collimation according to the at least one photographic image so that the given dimensions of the collimated X-ray beam are adjusted to dimensions of the patient's head determined from the at least one photographic image.
