Optimizing the quantity of X-rays received by a patient in a dental X-ray image acquisition system

A dental X-ray image acquisition system comprising:

• an X-ray generator comprising means for triggering the emission of X-rays, a timer enabling an operator to set a predetermined emission duration for said X-rays, and means for automatically stopping said emission at the end of said predetermined duration;
• and
• an intra-oral sensor sensitive to X-rays, associated with a command module for controlling said sensor, and adapted to acquire an image during said emission;
• said command module including means for starting said acquisition on detecting said triggering;
• wherein:
• said module includes means for receiving image acquisition data from the x-ray sensitive intra-oral sensor and means for generating a command for use by the generator, in application of at least one predetermined criterion related to the image acquisition data, to the generator to prevent, stop, or modify the emission power of said X-rays before the end of said predetermined duration, so as to control the quantity of X-rays emitted by the generator aiming in the acquisition of an image of good quality while not using an overdose of X-rays, and means for sending the command to the generator;
• and wherein
• said generator includes means for receiving said command, the means for stopping the generator being adapted to prevent, stop, or modify the power of said emission on receiving said command.
