MR Compatible Power Supply Module for PET Detectors of an Integrated PET/MR System

Power supply of positron emission tomography (PET) detectors is a serious issue for PET/magnetic resonance imaging (MRI) systems, due to mutual interaction between power supply electronics and MRI magnetic fields. We developed a prototype of a magnetic compatible power supply, that can be placed in an MRI system. The power supply is a compact ( null null 5.2\times 5.2null null null cm2) iron-free switching dc–dc converter. The power supply...
