摘要： An X-ray imaging apparatus including a sensor unit with a sensor array configured to generate a signal corresponding to X-rays and a sound-production unit configured to make a notification by sound production causes the sound-production unit to execute sound production in response to detection of an event. If an event including a sound-production request occurs during a period including a period of reading out a signal from the sensor array, the X-ray imaging apparatus restricts execution of sound production by the sound-production unit.

摘要： A radiation imaging apparatus includes a radiation detector, a storage unit, and a transfer unit. The radiation detector detects radiation transmitted through an object. The storage unit stores a radiation image based on the detected radiation. The transfer unit transfers the radiation image to an external information processing apparatus. The storage unit identifiably stores the radiation image to identify whether the radiation image is a radiation image transferred to the external information processing apparatus.
