PURPOSE:To enable the picture of time-phase which is important in test to be securely and majority-recorded, by making X-ray exposure to be performed on the program in accordance with the input set value of interrupt exposure speed by means of an outside switch, only when the captioned system is being operated. CONSTITUTION:Time (td) after a shadowing reagent is poured, X-ray exposure is performed at a repeating speed determined through Exposure Sequence. An operator looks at the picture on a TV monitor and when he judges that the concentration is sufficiently high, he pushes an interrupt exposure button on the operation pannel. The exposure repeating speed is changed into a speed shown by an interrupt exposure rate and set in a high-speed repeating condition. When the operator judges the time phase significant in test is just over, he pushes the interrupt exposure button and the interrupt exposure rate comes back to the former speed specified by the former Exposure Sequency. |
