Nuclear Magnetic Resonance Apparatus
First Claim
1. A magnet for a Magnetic Resonance Imaging apparatus, said magnet having at least two open sides, and delimiting a patient receiving area, said magnet comprising:
- two parallel magnetically permeable yoke elements; and
a transverse yoke element for connection of said two parallel elements, said magnet thus having a C shape, wherein in both parallel elements, an end portion associated to said transverse connection element has a transverse wall for connecting the two parallel elements with the transverse element, which has an end step for engagement of a corresponding end of said transverse element.

Abstract
A magnet for a Magnetic Resonance Imaging apparatus, said magnet having at last two, preferably three open sides, and delimiting the patient receiving area, said magnet being composed of three yoke elements, i.e. two parallel magnetically permeable elements and one transverse yoke element for connection of said two parallel elements, whereby said magnet has a C shape and wherein, for both of said parallel elements, the terminal portion associated to said transverse connecting element has a transverse wall for connection of said two parallel elements with the transverse element, which has an end step for engagement of a corresponding end of said transverse element.
