ABSTRACT:
The invention relates to a nuclear spin or NMR imaging assembly, comprising apparatus (1) for generating a homogeneous magnetic field in a region to be imaged of a target examined, sets of gradient coils (3) for producing one or more magnetic field gradients perpendicular to each other in said homogeneous magnetic field, a signal coil (2) surrounding at least substantially a region to be imaged for exciting said region with radio-frequency pulses and for receiving the generated NMR signals from the region to be imaged, amplifiers (5, 7) and filters (9, 10) for detected NMR signals, as well as a data processor and display equipment for imaging the collected information. According to the invention, the dimensions and location of a part to be imaged, including the region to be imaged and located inside said signal coil (2), are adapted to be determined in the direction of at least one gradient field, and the frequency band width of said filters (9, 10) is adapted to be controlled on the basis of said dimension and location information determined from a target to be imaged to an optimum value regarding the signal
oise ratio.
