ABSTRACT:
An X-ray television apparatus is provided with a mode switching circuit for switching from a one-shot radiographing mode to a hold radiographing mode and vice versa. In the one-shot radiographing mode, an X-ray picture obtained through a short time exposure to X-rays is recorded and reproduced. In the hold radiographing mode, an X-ray picture immediately before a continuous fluoroscoping operation is recorded and reproduced. In the one-shot mode, the record/reproduction is performed after a predetermined time from the turning-on of the operation switch. In the hold mode, the same is performed after a predetermined time from the turning-off of the operation switch.
