Calculation of the probability of a gradient coil amplifier failure using environmental data.

摘要

The present invention provides a medical device (100, 300, 500) having a processor. Execution of machine-executable instructions (120, 122, 124, 350, 352, 354) causes the processor to iteratively use a measurement database (116, 122) to include a plurality of data values (704). 114, 700) (200, 416), the plurality of data values including laboratory data (332) describing environmental conditions of the laboratory (322) of the magnetic resonance imaging system, wherein the plurality of data values Further includes technical room data (330) describing environmental conditions of the technical room (326) of the magnetic resonance imaging system, and by inputting the measurement vector into a trained neural network program (124), The probability (706) of failure of the magnetic field gradient coil amplifier (312) of the magnetic resonance imaging system in a given number of days. Calculated to (202,418).
