X-ray device for angiography or cardiology, has sensor unit detecting distance between patient and recording device, and control unit adjusting operating parameter, which concerns image quality of recording device based on measured signal

摘要

The device (1) has a recording device with a x-ray tube (4) and an x-ray detector (5), and a control unit (9) determining a parameter of a patient (2) to be examined. The control unit adjusts an operating parameter of the recording device based on the patient parameter. A sensor e.g. ultrasonic distance sensor (12), unit detects a distance between the patient and the recording device and transmits a distance measured signal to the control unit that adjusts the operating parameter, which concerns the image quality of the recording device based on the measured signal.
