Abstract
There is provided a power source for continuously energizing electrically isolated devices used to monitor the physiological state of a subject undergoing an examination in an NMR scanner having a magnet, RF and gradient coils. The power source is made up of a first element for generating energy of one type and a second element for receiving this energy and converting it to a second energy type used to energize the electrically isolated devices. The first and second elements are operatively coupled to one another through an electrically isolated medium to permit continuous transfer of energy from the first to the second element and to reject interference due to the NMR apparatus subsystems. In one embodiment the first element may be an array of light-emitting diodes, while the second element may be an array of photovoltaic cells. In another embodiment, the first and second elements may be ultrasonic transducers coupled through air or a ceramic substrate.
