Power and communication interface between a digital X-ray detector and an X-ray imaging system

摘要

A system for eliminating image artifacts caused by electromagnetic interference (EMI) on a portable digital x-ray detector that is capable of non-contact wireless inductively coupled power transfer and capacitively coupled communication and data transfer. An X-ray imaging system comprising a portable digital X-ray detector inductively and capacitively coupled to a power source and communication device that is coupled to a detector receptacle of the X-ray imaging system when the portable digital X-ray detector is located within the detector receptacle to transfer power from a power supply of the power source and communication device to the portable digital X-ray detector and transfer communication and data between the power source and communication device and the portable digital X-ray detector.
