Management system for X-ray detector and X-ray diagnosis apparatus

An X-ray diagnosis apparatus storing a plurality of X-ray detectors, and comprising:

• an X-ray generator which irradiates X-rays to any one of the plurality of X-ray detectors;
• and
• processing circuitry which controls the X-ray detector and the X-ray generator to perform X-ray imaging, the processing circuitry being configured to
• diagnose operation states of detecting elements configuring an X-ray detector of the X-ray detectors,
• for a diagnostic photographing mode, perform X-ray imaging on a subject, and for inspection modes, inspect the X-ray detector,
• in the inspection mode, inspect regularly diagnosis results of a diagnosis performed by the processing circuitry, and perform operation inspection on each of the X-ray detectors in an operation state of the X-ray imaging, and
• set a validity period to establish whether inspection results inspected are valid or not,
• wherein the processing circuitry is further configured to
• determine whether the inspection results at operation-start inspection are normal or not,
• determine whether elapsed time from start of recording the inspection results exceeds the validity period or not, and
• even when the inspection results are normal, control the X-ray detector and the X-ray generator not to perform the X-ray imaging on a subject when the elapsed time exceeds the validity period and the inspection results are determined to be invalid based on the validity period.
