Abstract

An apparatus and method are provided for pelvic imaging using a saddle shaped magnetic resonance imaging system. The apparatus includes an array of electropermanent magnets having a longitudinal length that is longer than a width so that the subject may straddle the length of the array and sit on it

First claim

1 . An apparatus for collecting magnetic resonance images of a subject's pelvic region, the apparatus comprising:
an array of electropermanent magnets configured to be straddled by the subject during imaging, and to form an image of structures in the subject's pelvic region.

2 . The apparatus of claim 1 , wherein the array of electropermanent magnets are arranged in a saddle shape for the subject to be seated on during the imaging.

3 . The apparatus of claim 2 , wherein the array of electropermanent magnets has a longitudinal axis that is longer than a width of the array, wherein a cover is coupled to the array for the subject to sit on.

4 . The apparatus of claim 1 , wherein the apparatus further comprises power supply and switching and monitoring circuitry coupled to the electropermanent magnets.

5 . A method of collecting magnetic resonance images of a subject's pelvic region, the method comprising:
providing an array of electropermanent magnets, positioning a subject in a straddle position over the array of electropermanent magnets; and imaging the subject's pelvic region

6 . The method of claim 5 , wherein the array of electropermanent magnets are arranged in a saddle-shape for the subject to he seated on during the imaging.

7 . The apparatus of claim 6 , wherein the array of electropermanent magnets has a longitudinal axis that is longer than a width of the array, wherein a cover is coupled to the array for the subject to sit on.

8 . The method of claim 5 , wherein the apparatus further comprises a power supply and switching and monitoring circuitry in order to perform magnetic resonance imaging.
