This Won't Work
Having helped design and manufacture diagnostic imaging systems ie., computer controlled, ultrasound imaging, digital x-ray and differential transmission spectroscopy ie., breast cancer detection using light, I cannot see anyway this detection system will work. First would be the large isolation transformers required to meet the UL 544 leakage current requirements. Next would be the line filter required to meet the FCC Part 15 requirements. After that, there are usually a combination of several linear power supplies for the digital systems and some switching power supplies for any motors ie., disk drives, ultrasonic transducer drives, auto-focusing for lenses.
All of these systems ie., imaging devices, have their outputs connected by either Ethernet or USB or both to servers. Attempting to monitor the AC line to detect malware IMHO seems like a waste of time. Even the laptop type of control and monitoring for some Ultrasound and EKG systems, still have to meet the leakage current requirements ie., 10 microamps, for directly connected to the patient systems. The transformers and filters required in the main AC line would defeat the purpose of such monitoring.as described.
