Publication number: 20240057961Abstract: An intra-oral imaging system includes an imaging device and a control device. The imaging device includes an imager, a controller, and a case in which the imager and the controller are housed. The imager performs imaging detection for detecting radiation in order to acquire an image of an object and monitoring detection for detecting radiation in order to monitor the dose of radiation. The controller transmits an imaging signal and a monitoring signal to the control device, the imaging signal acquired by the imaging detection and the monitoring signal acquired by the monitoring detection. The control device receives the imaging signal and the monitoring signal, and transmits a control command to the controller, the control command generated based on the monitoring signal. The controller controls the imager according to the control command.Type: ApplicationFiled: January 4, 2022Publication date: February 22, 2024Applicant: HAMAMATSU PHOTONICS K.K.Inventors: Shigehiro KITAMURA, Kazuhisa MIYAGUCHI
