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

Patent number: 6553095Abstract: An apparatus and method used in dental panoramic and cephalographic x-ray equipment provides automatic adjustment of the pre-programmed exposure factors in order to obtain optimisation of the grey scale of the latent image on various kinds of x-ray detectors, such as the radiographic film or x-ray image detector plates. A sensor, such as photo diodes, detects the intensity of the radiation passed through the patient and incident on the x-ray detector and feeds it to a control unit. The control unit provides a computed simulation of the latent image grey level and adjusts the programmed exposure factors in order to establish the grey level of the latent image at the required reference value.Type: GrantFiled: December 19, 2001Date of Patent: April 22, 2003Assignee: Dentsply Research & Development CorpInventors: Gerardo Rinaldi, Giuseppe Rotondo, Gianfranco Venturino
