Title:
HIGH FREQUENCY SIGNAL-PROCESSING METHOD AND HIGH FREQUENCY SIGNAL PROCESSOR AND MAGNETIC RESONANCE-PHOTOGRAPHING EQUIPMENT
Document Type and Number:
Japanese Patent JP3490173
Kind Code:
B2
Abstract:
PURPOSE: To realize a high frequency signal-processing method and high frequency signal-processing equipment capable of deciding the directivity of plural coils, paralleling on a prescribed plane including the coil plane, in transmitting or receiving without changing the geometrical state in a static magnetic field space.
CONSTITUTION: This high frequency signal-processing equipment has plural coils 201 and 202 paralleling in a plane including the coil plane and a directivity deciding means 30 to decide the directivity of electromagnetic wave transmission according to the embodiment of signal supply in supplying plural high frequency signals to the coils 201 and 202 respectively or to decide the directivity of electromagnetic wave reception according to the embodiment of addition of plural signals with respective origin to signals received by the coils 201 and 202.
