Patent number: 7016466Abstract: An apparatus and method used in intra-oral dental x-ray imaging equipment provides automatic detection of the x-ray emission in order to obtain timely transition to the image integration and acquisition phase with high level of rejection of false triggering induced by blemish defects of the image sensor or by variations of the ambient and temperature conditions. A solid state imager, such as a CCD image sensor, is continually clocked during the standby phase prior to irradiation from an X-ray source, so providing on same time an output signal proportional to the accumulated dark current and the continuous removal of the same. A control unit analyses the output signal of the imager, detects the variation caused by the start of the x-ray emission using appropriate threshold levels, and automatically triggers the imager to the image integration and acquisition phases.Type: GrantFiled: June 18, 2004Date of Patent: March 21, 2006Assignee: Gendex CorporationInventors: Gerardo Rinaldi, Venturino Gianfranco, Giuseppe Rotondo
