Method to generate magnetic fields of high uniformity and compensation of external dispersed field, and system for its embodiment

摘要

The present invention relates to a method to generate magnetic fields of high uniformity within the object examined and compensation of external dispersed field, and a system for its embodiment, which method is applicable in magnetic resonance tomography. The method to generate magnetic fields of high uniformity within the object examined in which two pairs of coils (1) and (2) are used in which the current flows in the same direction and sense. The system is composed of two pairs of coils (1) and (2), which, preferably, have the same radiuses, are situated coaxially, are attached to the housing of the tomograph in a permanent, detachable manner, and in which the current flows in the same direction and sense.
