Patent number: 10405823Abstract: A radiation imaging apparatus secures subject safety and includes a wireless communication unit of an operation panel and a wireless communication unit of a control unit performing periodical wireless communication. While operating, it is determined if wireless communication unit of the control unit is receiving a wireless communication signal from the wireless communication unit of the operation panel, or not. Then, when the wireless communication unit of the control unit is not receiving the wireless communication signal from the wireless communication unit of the operation panel, a movement control element of the control unit executes an emergency shutdown operation to halt movement of a support table, a X-ray tube, a collimator and a X-ray detector.Type: GrantFiled: September 6, 2018Date of Patent: September 10, 2019Assignee: SHIMADZU CORPORATIONInventors: Keita Okutani, Masahiro Tanaka
