Description
- This application claims priority to U.S. application Ser. No. 10/177,625 filed Jun. 12, 2002, which application is incorporated by reference and made a part hereof.
- The present invention relates to MRI systems, and more specifically to a patient bed support that positions patients within an open MRI system.
- Patients seeking medical treatment typically need to be positioned correctly in order to properly receive diagnosis or treatment. One example is in magnetic resonance imaging (MRI) systems that scan portions of a patient's anatomy within a relatively small imaging volume.
- One example of an open MRI system is the FONAR 360° system designed by Fonar Corporation. Another example is the OR-360°™ (MRI Operating Room), also designed by Fonar Corporation. FONAR 360° systems include magnetic poles that are part of a FONAR 360° scanner. The poles are typically located in the approximate center of a room with one pole protruding from the ceiling and the other pole protruding from the floor. The patient is positioned in the space, or gap, between the two poles and is accessible from virtually any angle. The patient can be placed on his back, stomach or side. A large portion of the MRI system may be located outside the scanning room such that primarily the patient is exposed to the main magnetic field.
-
FIG. 1 illustrates a portion of an exampleopen MRI system 10.MRI system 10 includes amagnet 11.Magnet 11 includes anupper pole assembly 12 and alower pole assembly 14 with agap 16 between the upper andlower pole assemblies - A scanning operation is typically done by positioning a patient bed 17 (which includes a patient) within gap 16 (note arrow X) between upper and
lower pole assemblies patient bed 17 includes a frame that is made up a slab 18 and fourlegs 19 that support slab 19. Eachleg 19 typically includes a roller orcaster 20 forrolling bed 17 across the floor. The space underslab 18 and betweenlegs 19 is large enough to receivelower pole assembly 14 whenpatient bed 17 is moved intogap 16. - The present invention relates to a patient bed support for maneuvering a patient in an open MRI system that includes an upper pole assembly and a lower pole assembly. The patient bed support includes a frame for attaching the patient bed support to the lower pole assembly in the MRI system and a member movably attached to the frame to maneuver patients that are placed on the member relative to the lower and upper pole assemblies of the MRI system.
- In another example embodiment, the present invention relates to a patient bed support for maneuvering a patient in an MRI system that includes an upper pole assembly and a lower pole assembly. The patient bed support includes a first ring that is used to couple the patient bed support to the lower pole assembly in the MRI system and a second ring rotatably attached to the first ring. The patient bed support further includes a platform that supports a patient during scanning within the MRI system. The platform is coupled to the second ring such that the patient is maneuvered within the MRI system by rotating the second ring relative to the first ring.
- The present invention also relates to an MRI system that includes a lower pole assembly, an upper pole assembly and a patient bed support between the upper and lower pole assemblies. The patient bed support includes a frame that is coupled to the lower pole assembly and a member that is movably coupled to the frame. The member is moved relative to the lower pole assembly of the MRI system in order to accurately position patients within the MRI system.
- A patient bed support for patient handling and positioning has been devised which is faster, more accurate, and more flexible in positioning patients in open MRI systems. The patient bed support attaches to a lower pole assembly and bears the weight of a patient bed that is positioned above the lower pole assembly during a scanning procedure. In some embodiments, the patient bed support rotates to allow the patient to be positioned in various orientations between the upper and lower pole assemblies of the MRI magnet.
- The MRI system may be used in conjunction with a patient bed that includes casters for rolling the patient bed across a floor toward a lower pole assembly that has 360 degree access around it. The bed is sized to allow it to be rolled over the patient bed support that is mounted on the lower pole assembly. The patient bed support may also include means for raising the patient bed such that the bed can swivel freely.

FIGS. 2 and 3 show apatient bed positioner 120 embodying the present invention that is utilized inportion 130 of an MRI system embodying the present invention.MRI system 130 includes a magnet which is made up of anupper pole assembly 132 and alower pole assembly 134.Patient bed support 120 is attached tolower pole assembly 134 such thatpatient bed support 120 is positioned within a gap 136 between the upper andlower pole assemblies Upper pole assembly 132 is not shown inFIG. 3 for purposes of clarity. -
MRI system 130 is used in conjunction with apatient bed 110 that includes aframe 111 having fourlegs 113. Eachleg 113 includes a roller orcaster 114 at an end thereof forrolling bed 110 across afloor 105. Grooves (not shown) can be provided infloor 105 to guidebed 110 as it is being rolled intoMRI system 130. - A
slab 112 may be located on top ofbed 110. As indicated byarrow 115,slab 112 may be configured to translate linearly along the length ofbed 110 to more accurately position the patient within gap 136.Portion 130 may also include sensors and controllers that are used to even more precisely position slab 112. -
Patient bed support 120 is configured to be coupled tolower pole assembly 134. In one embodiment,patient bed support 120 rises up in a vertical direction relative to thefloor 105 and rotate in the same plane as the floor.Patient bed support 120 may be made from plastic, composite, ceramic, or other non-metallic or non-magnetic materials. It can be driven via a screw drive, a scissor lift or other equivalent means, such as pneumatic and hydraulic.Patient bed support 120 may also be driven by servo-motors that precisely drive and control the position ofpatient bed support 120. - When a patient is to be scanned, patient bed 110 (which includes a patient thereon) is rolled over the
lower pole assembly 134 andpatient bed support 120 as indicated byarrow 116. The bed is sized so that there is clearance between a bottom 117 ofbed 110 andpatient bed support 120. Whenbed 110 is properly positioned within the magnet,patient bed support 120 is raised.Patient bed support 120 contacts abottom surface 117 ofpatient bed 110 and liftsbed 110 off of thefloor 105. The weight of the bed is transferred from the floor topatient bed support 120.Slab 112 may be a separable part ofpatient bed 110 such thatslab 112 is the only part ofbed 110 which is lifted. - Once
bed 110 has been lifted, it is then freely rotatable on top of the bottom patient bed support. This allows medical personal to position the bed and move around the bed as needed. Sensors may be used to monitor the rotation of the bed such that an operator can use computer controls to position a patient. The associated computer may also be able to configure the corresponding MRI scans on a monitor or print-out. When the MRI procedure is completed,patient bed support 120 is lowered down to its original position and thepatient bed 110 is rolled out of the scanner.Bed 110 may be rolled out of the same side of the magnet as where it entered, rolled out the other side to provide more efficient use of the scanner, and/or rolled out of the scanner in any direction. - Open MRI systems allow a patient to be positioned upon a bed in a dressing room, and then rolled into the scanner room. Patient beds can be inserted from any direction because of the 360 degrees access provided by open MI systems.
- Although
FIGS. 2 and 3 show platform 142 oriented transversely toslab 112 onpatient bed 110 for purposes of clarity,platform 142 is preferably oriented so that it is entirely underslab 112.Positioning platform 142 underslab 112 preventsplatform 142 from inhibiting medical personnel as they maneuver around a patient during scanning and surgical procedures.
