Title:
X-RAY DIAGNOSTIC DEVICE, METHOD FOR DETECTING SIGN OF FAILURE OF X-RAY TUBE, AND ROTATING-POSITIVE-ELECTRODE X-RAY TUBE
Document Type and Number:
WIPO Patent Application WO/2015/079883
Kind Code:
A1
Abstract:
A failure sign detection device (9) for an X-ray diagnostic device (1) correlates and acquires the orientation angle of a rotating-positive-electrode X-ray tube (10) measured by a motion sensor (22) and vibration data of the rotating-positive-electrode X-ray tube (10) measured by a vibration sensor (21), and detects a sign of failure of the rotating-positive-electrode X-ray tube (10) on the basis of the amount of time-dependent change in the vibration data since the start of use of the rotating-positive-electrode X-ray tube (10) for each of a plurality of orientation angles.
