1. A magnetic resonance imaging (MRI) magnet, comprising:
- a first section having a first housing and a first set of magnet coils arranged about a common axis, the first set of magnet coils including coils proximate the common axis; and
a second section having a second housing and a second set of magnet coils arranged about the common axis, the second set of magnet coils being radially displaced from the common axis;
wherein the second section is connected to but axially displaced a distance “
d”
from the first section.

Abstract
A magnetic resonance imaging (MRI) magnet having a first section and a second section is disclosed. The first section has a first housing, and a first set of magnet coils arranged about a common axis that include coils proximate the common axis. The second section has a second housing, and a second set of magnet coils arranged about the common axis where the coils are radially displaced from the common axis. The second section is connected to but axially displaced a distance “d” from the first section.

17. A magnetic resonance imaging (MRI) magnet, comprising:
-
a closed magnet having a first housing and a first set of magnet coils arranged about a common axis, the first set of magnet coils including coils proximate the common axis;
an open ring-shaped magnet having a second housing and a second set of magnet coils arranged about the common axis, the second set of magnet coils being radially displaced from the common axis thereby providing an axial opening to allow end access to an object disposed between the closed and open magnets; and
the open magnet being connected to but axially displaced a distance “
d”
from the closed magnet via a set of supports that provide openings to allow side access to the object disposed between the closed and open magnets.

18. A magnetic resonance imaging (MRI) system, comprising:
-
a MRI magnet; and
a control system for controlling the operation of the MRI magnet such that MRI data of an object may be generated and saved for subsequent post-processing and analysis;
wherein the MRI magnet comprises;
a first section having a first housing and a first set of magnet coils arranged about a common axis, the first set of magnet coils including coils proximate the common axis;
a second section having a second housing with an axial opening therethrough and a second set of magnet coils arranged about the common axis, the second set of magnet coils being radially displaced from the common axis;
the second section being connected to but axially displaced a distance “
d”
from the first section via a set of supports with side openings therebetween; and
wherein side access through the side openings and end access through the axial opening is allowed to an object disposed between the two sections.

19. An open MRI magnet assembly comprising:
-
a closed ended magnet; and
an open ended magnet connected to the closed ended magnet and having a volume defined therebetween, the open ended magnet having an opening therethrough to allow access to the volume defined between the open ended magnet and the closed ended magnet. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)
