Abstract

Apparatus and method for using radio frequency coil systems for magnetic resonance imaging within an open architecture apparatus is provided. The MRI coil system includes a support structure with an open architecture in which secondary support structures, compression systems and plates containing RF coil systems may be introduced. These structures and RF coils can be moved relative to the patient, or removed entirely from the system. In one embodiment the system consists of a tabletop coil system, while another embodiment consists of a dedicated stretcher design.

Claims (28)

1. A patient support and magnetic resonance imaging (MRI) system for a patient, comprising:

a main support structure configured to support an anatomy of a patient;

a first component support structure moveably connected to the main support structure, wherein the first component support structure is configured to position a patient's tissue in a position for imaging; and

a first RF coil system configured to be received and releasably attached to the first component support structure so that first RF coil system is positioned adjacent to the patient's tissue, and is active when the first component support structure is locked in a position for imaging the patient's tissue;

wherein the first component support structure is configured to receive and release the first RF coil system.

2. The system of claim 1 , wherein the first component support structure is configured to position the first RF coil system adjacent to the patient's tissue.

3. The system of claim 2 , wherein the first component support structure is configured to provide a plurality of compression configurations for the patient's tissue.

4. The system of claim 1 , wherein the first component support structure comprises at least one locking component to lock the first component support structure in position.

5. The system of claim 1 , wherein the first component support structure is configured to move along an anterior-posterior plane.

6. The system of claim 1 , wherein the first component support structure is configured to move along a medial-lateral plane.

7. The system of claim 6 , wherein the main support structure comprises at least one track constructed and arranged along the medial-lateral plane, and wherein the first component support structure is moveably coupled to the track.

8. The system of claim 1 , wherein the first RF coil system comprises a medial RF coil held by the first component support structure.

9. The system of claim 1 , wherein the first RF coil systems comprises a lateral RF coil held by the first component support structure.

10. The system of claim 9 , wherein the first component support structure is configured to provide unilateral imaging of one of a patient's breasts.

11. The system of claim 1 , further comprising a second component support structure configured to receive a second RF coil, wherein the first RF coil is a lateral coil and the second RF coil is a medial coil held by respective first and second component support structures.

12. The system of claim 11 , wherein the second component support structure is configured to lock in a position adjacent to the patient's tissue for imaging.

13. The system of claim 11 , wherein the respective first and second component support structures are configured to be positioned for bilateral imaging of the tissue.

14. The system of claim 1 , wherein the first component support structure is configured to receive and release at least one of an interventional and a guidance device.

15. The system of claim 14 , wherein the interventional device is configured to provide at least one access aperture for interventional procedures on patient's tissue.

16. A method for magnetic resonance imaging (MRI) a patient, the method comprising:

accepting a patient's tissue to be imaged into a main support structure;

holding a first RF coil system with a first component support structure moveably attached to the main support structure, the first RF coil system being received and releasably attached to the first component support structure;

moving the first component support structure and the first RF coil system relative to the main support structure into a position adjacent to the patient's tissue to be imaged thereby defining a first imaging configuration; and

activating the first RF coil system and imaging, with an MRI imager, the patient's tissue with the first component support structure and the first RF coil system when in the first imaging configuration.

17. The method according to claim 16 , further comprising locking the first component support structure and the first RF coil system into the first imaging configuration for imaging.

18. The method according to claim 16 , further comprising providing a second component support structure housing a second RF coil system to define a second imaging configuration.

19. The method according to claim 18 , further comprising moving at least one of the first and second component support structures having a respective RF coil system to define the second imaging configuration.

20. The method according to claim 19 , further comprising imaging the patient's tissue according to the second imaging configuration.
