Calculation of the probability of gradient coil amplifier failure using environment data

摘要

The invention provides for a medical instrument (100, 300, 500) comprising a processor. Execution of machine executable instructions (120, 122, 124, 350, 352, 354) cause the processor to repeatedly: construct (200, 416) a measurement vector (114, 700) comprising multiple data values (704) using a measurement database (116, 122), wherein the multiple data values comprise examination room data (332) descriptive of the environmental conditions of an examination room (322) of a magnetic resonance imaging system, wherein the multiple data values further comprise technical room data (330) descriptive of the environmental conditions of a technical room (326) of the magnetic resonance imaging system; and calculate (202, 418) a probability (706) of failure of a gradient coil amplifier (312) of the magnetic resonance imaging system a predetermined number of days in the future by inputting the measurement vector into a trained neural network program (124).
