What are the domestic and international EMC (electromagnetic compatibility) standards for CT scanners?

As high-precision imaging devices, CT scanners adhere to EMC standards based on GB 9706.1 and YY 0505 domestically, and IEC 60601-1-2 internationally. These standards rigorously regulate the emission and immunity limits of the equipment in complex electromagnetic environments. CT scanners involve slip ring power supply, high-speed data transmission (e.g., GigE Vision), motor drives, and high-voltage generators, making EMC design challenging. For carbon brush spark noise from the slip rings, PBZ series power inductors can be used for filtering. The differential signal integrity of the data link is crucial; the CML4532A-510T common-mode inductor effectively suppresses common-mode noise. SMBJ/SMCJ series TVS diodes must be used on the DC power rails of each system board for transient voltage suppression to protect sensitive ICs.
