Breast coil for use in magnetic resonance imaging
The present disclosure relates to a receive coil assembly for use in magnetic resonance imaging of breast tissue. In certain embodiments the assembly comprises separable parts: a configurable mechanical support and a flexible receive coil array. The adjustability and separability of the receive coil array relative to the mechanical support allows the receive coil array to substantially conform to the breasts of the patient during imaging.
1. A breast imaging assembly for use in a magnetic resonance imaging system, the assembly comprising:
a mechanical assembly comprising:
a patient facing surface configured to support a patient in a breast imaging position;
an opening within the patient facing surface through which the breasts of the patient pass when the patient is supported by the mechanical assembly; and
a removable insert configured to fit within the opening, the removable insert comprising slots;
an electrical assembly that is separable from the mechanical assembly, the electrical assembly comprising:
a flexible substrate configured to removably couple to the mechanical assembly through the slots to conform around medial and lateral surfaces of a patient's breasts; and
a plurality of receive coils embedded within the flexible substrate.
2. The breast imaging assembly of claim 1 , wherein the mechanical assembly comprises a housing component having the patient facing surface and opening, wherein the housing component further comprises a lateral opening on either side of the opening.
3. The breast imaging assembly of claim 1 , wherein the mechanical assembly comprises a sternum support configured to fit within the opening so as to divide the opening into two respective portions.
4. The breast imaging assembly of claim 3 , wherein the sternum support is adjustable along an axis running through the opening.
5. The breast imaging assembly of claim 1 , wherein the electrical assembly comprises a plurality of linear arrangements of electrical components within the flexible substrate.
6. The breast imaging assembly of claim 5 , further comprising a plurality of ribs, wherein each rib is configured to affix to the flexible substrate over at least one of the plurality of linear arrangements of electrical components.
7. The breast imaging assembly of claim 1 , wherein the electrical assembly further comprises a foam spacer disposed on the flexible substrate.
8. The breast imaging assembly of claim 1 , wherein the plurality of receive coils comprises more than 8 receive coils.
9. The breast imaging assembly of claim 1 , wherein the plurality of receive coils comprises 31 receive coils.
10. The breast imaging assembly of claim 1 , wherein the plurality of receive coils is arranged as three rows of receive coils.
11. A mechanical support for breast imaging, comprising:
a housing component, comprising:
a patient facing surface;
an opening defined in the patient facing surface; and
a lateral opening on either side of the opening;
a sternum support configured to fit within the opening such that, when fitted within the opening, the sternum support divides the opening into two respective portions;
a removable insert configured to fit within the opening, the removable insert comprising slots through which ends of a removable electrical assembly are treaded to conform around medial and lateral sides of a patient's breast.
12. The mechanical support of claim 11 , wherein the sternum support comprises a support component and an overlying component that are movable or removable with respect to one another.
13. The mechanical support of claim 11 , wherein the sternum support is configured to be adjusted along an axis running through the opening.
