Abstract

An accessory kit is provided for interventional procedures using a magnetic resonance imaging scanner. The accessory kit includes a patient support and an electrical connection adapter. The patient support has a first end proximal and a second end distal to the scanner. The distal end is configured to create a space to accommodate a clinician, such as narrowing of the distal end or at least one cutout on a side of the distal end. The electrical connection adapter interfaces with the scanner and a scanner table. The accessory kit is configured so that when the proximal end is extended into the scanner bore, the distal end extends outside the bore. The narrowed width and/or cutout(s) of the exposed distal end and the extended gap between the scanner and scanner table create space on at least one side of the patient support that a clinician may use to access a patient.

First claim

What is claimed is:

1. An electrical connection adapter and patient support system for use with an MR scanner and an MR scanner table during interventional procedures using magnetic resonance imaging, the electrical connection adapter and patient support system comprising:
a patient support configured to be positioned on the MR scanner table; and
an electrical connection adapter comprising:
an external enclosure;
a proximal connector positioned at a proximal end of the external enclosure, the proximal connector being configured to electrically couple the electrical connection adapter to a connector of the MR scanner; and
a distal connector positioned at a distal end of the external enclosure, the distal connector being configured to electrically couple the electrical connection adapter to a connector of the MR scanner table;

wherein the electrical connection adapter is configured to be interposed between the MR scanner and the MR scanner table, thereby creating or extending a gap between the MR scanner and the MR scanner table;
wherein the patient support has a surface extending between the proximal end and a distal end of the patient support; and
wherein at least one recess is defined in at least one side of the patient support and extends inwardly from a perimeter of the patient support toward a central region of the patient support, the at least one recess being positioned at a distal end portion of the patient support and is adapted to extend into the gap between the MR scanner and MR scanner table when created or extended by the electrical connection adapter, and is longitudinally co-located with the gap between the MR scanner and MR scanner table when created or extended by the electrical connection adapter, thereby forming a space configured to at least partially receive a medical professional for access during the interventional procedures using magnetic resonance imaging.

2. The electrical connection adapter and patient support system of claim 1 , wherein the electrical connection adapter further comprises additional ports for supplemental power and data output.

3. An MR imaging system configured for use during interventional procedures using magnetic resonance imaging, the MR imaging system comprising:
an MR scanner;
an MR scanner table movable relative to the MR scanner; and
the electrical connection adapter and patient support system of claim 1 , the electrical connection adapter being interposed between the MR scanner and the MR scanner table, thereby creating or extending the gap between the MR scanner and the MR scanner table, and the distal connector of the electrical connection adapter being electrically coupled to a connector of the MR scanner table;
wherein the patient support is positioned on the MR scanner table and is movable relative to the MR scanner table towards a bore of the MR scanner and a proximal end of the patient support extends into the bore of the MR scanner and extends into the gap defined between the MR scanner and MR scanner table created or extended by the electrical connection adapter.

4. The MR imaging system of claim 3 , wherein the at least one recess extends to the distal end of the patient support such that a width of the patient support at the distal end of the patient support is narrower than a width of the patient support at the proximal end of the patient support.

5. The MR imaging system of claim 3 , wherein the patient support replaces the existing surface of the MR scanner table.

6. The MR imaging system of claim 3 , wherein the patient support further comprises at least one filler plate positionable to fill in the at least one recess.

7. The MR imaging system of claim 3 , wherein at least one of the electrical connection adapter or the patient support is at least partially integrated into the construction of the MR scanner.

8. The MR imaging system of claim 3 , wherein the MR imaging system further comprises components for interactive interventional radiology.

9. The MR imaging system of claim 3 , further comprising: a secondary support configured for use with the patient support, wherein the secondary Support further comprises at least one low friction element.

10. The MR imaging system of claim 9 , wherein said low friction element comprises at least one air bearing further having at least one port configured to introduce air into the at least one air bearing.

11. The MR imaging system of claim 9 , wherein the secondary support is configured to be movably positioned on the surface of the patient support, including moving laterally across a width of the patient support and moving rotatably about an axis perpendicular to the surface of the patient support.

12. A method of configuring an MR imaging system for access during interventional procedures using magnetic resonance imaging, the method comprising:
installing a patient support having a patient surface on an MR scanner table;
engaging a proximal connector of an electrical connection adapter with a connector of an MR scanner;
engaging a connector of the MR scanner table with a distal connector of the electrical connection adapter such that the electrical connection adapter is interposed between the MR scanner and the MR scanner table, thereby creating or extending a gap between the MR scanner and the MR scanner table; and
extending a proximal end of the patient support into a bore of the MR scanner such that the proximal end of the patient support extends into the bore of the MR scanner, at least a portion of at least one recess of the patient support extends to a location corresponding to the gap between the MR scanner and the MR scanner table, and the at least one recess of the patient support is longitudinally co-located with the gap between the MR scanner and the MR scanner table created or extended by the electrical connection adapter in order to at least partially receive a medical professional.

13. The method of claim 12 , further comprising the step:
placing a secondary support having an air bearing and port to introduce air into the at least one air bearing on the secondary support.
