MRI PROBE MAGNET AND COIL CONFIGURATIONS

摘要

A magnet assembly for a self-contained MRI probe having a longitudinal axis in a z-direction, the probe adapted to image an imaging region located relative to the probe, in terms of a Cartesian x-y-z coordinate system, at least partly in a positive x direction, the magnet assembly comprising magnet portions which produce a static magnetic field in the imaging region, including at least: a) a first portion located at y < 0, with magnetization having a positive y component and a negative x component; and b) a second portion, located at y > 0, with magnetization having a positive y component and a positive x component.
