Fault identification in medical imaging system electrical circuits

A computer-implemented method of identifying a potential fault in an electrical circuit comprising a component of a medical imaging system and a switching power supply configured to supply power to the component, the method comprising:

• receiving radiofrequency, RF, signals generated by the switching power supply during operation of the electrical circuit;
• and
• determining, based on the received RF signals, an amplitude and/or a phase of one or more harmonic frequencies of a switching frequency of the switching power supply, and which one or more harmonic frequencies are generated by the switching power supply in response to a loading of the switching power supply by the component;
• and
• identifying the potential fault in the electrical circuit based on the determined amplitude and/or phase of the one or more harmonic frequencies.

A computer program product comprising instructions which when executed by one or more processors, cause the one or more processors to carry out a method of identifying a potential fault in an electrical circuit comprising a component of a medical imaging system and a switching power supply configured to supply power to the component, the method comprising:

• receiving radiofrequency, RF, signals generated by the switching power supply during operation of the electrical circuit;
• and
• determining, based on the received RF signals, an amplitude and/or a phase of one or more harmonic frequencies of a switching frequency of the switching power supply, and which one or more harmonic frequencies are generated by the switching power supply in response to a loading of the switching power supply by the component;
• and
• identifying the potential fault in the electrical circuit based on the determined amplitude and/or phase of the one or more harmonic frequencies.
