Abstract :
The distinctive property of the proposed flexible receiver coil consists in that it allows to change both the form and volume of the area enclosed in this coil. The sample occupies the whole volume of the coil. Signal to noise ratio is improved due to the reduction of the part of the electromagnetic power which is scattered by excited nuclear spin system in the surrounding environment. The technology of a proposed receiver coil manufacturing allows to vary the pitch and type of conductors. It allows to increase the loop area of the coil in order to reduce the resistance and improve quality factor of the receiver oscillating circuit which also improves signal to noise ratio
