Chest wall coil array for breast imaging
View Patent ↗A RF coil array is provided for imaging a chest wall of a patient including a breast. The RF coil array includes a rigid cup-shaped element and a flexible, substantially flat portion. The rigid cup-shaped element is sized and dimensioned to receive a small breast, such as a post mastectomy breast or a male breast, and the flexible portion is configured to be conformed to the patient adjacent the breast to allow for imaging of the breast, and adjacent areas while facing the chest wall.
1. A coil array for immobilizing the tissue to be imaged against the chest wall of a patient, the coil array comprising:
a flexible mounting element;
an RF coil array formed on the flexible mounting element;
a rigid cup-shaped element coupled to the flexible mounting element, wherein the rigid cup-shaped element is sized and dimensioned to receive a breast while facing the chest wall of the patient, and wherein the flexible mounting element is configured to be bent to position the RF coil adjacent to the patient; and
an adjustment device positioned adjacent the flexible mounting element, and configured to bend the flexible mounting element to conform to the body of the patient adjacent the breast, wherein the adjustment device is receivable in a patient support structure and is configured to move laterally along a lateral track provided in the patient support structure.
2. The coil array as recited in claim 1 , wherein the flexible mounting element includes a generally flat flexible portion adjacent the rigid cup-shaped element.
3. The coil array as defined in claim 1 , wherein the adjustment device is coupled to a vertical track and is configured to move along the vertical track.
4. The coil array as defined in claim 3 , wherein the vertical track is coupled to the lateral track.
5. The coil array as defined in claim 1 , wherein the flexible mounting element is comprises a material that can be bent into and retain a position adjacent an anatomy of interest in the patient.
6. A kit for breast imaging, the kit comprising:
a chest wall coil array comprising:
a flexible mounting element;
an RF coil array formed on the flexible mounting element;
an adjustment device positioned adjacent the flexible mounting element, and configured to bend the flexible bending element to conform a body of a patient adjacent a breast, wherein the adjustment device is mounted to be moveable vertically and laterally, to bend the chest wall array in two dimensions; and
a rigid cup-shaped element coupled to the flexible mounting element, wherein the rigid cup-shaped element is sized and dimensioned to receive the breast while facing the chest wall of the patient, and wherein the flexible mounting element is configured to be bent to position the RF coil adjacent the patient and to immobilize the tissue of the patient using compression; and
a lateral array comprising:
a substantially flat mounting element;
an RF coil array formed on the mounting element;
wherein the chest wall coil array is configured for immobilization of tissue in all directions using compression substantially perpendicular to the chest wall of the patient including the breast, and the lateral array is configured for immobilizing breast tissue in all directions using compression in the medial-lateral direction adjacent to the chest wall.
7. A coil array for immobilizing the tissue to be imaged against the chest wall of a patient, the coil array comprising:
a flexible mounting element;
an RF coil array formed on the flexible mounting element;
a rigid cup-shaped element coupled to the flexible mounting element, wherein the rigid cup-shaped element is sized and dimensioned to receive a breast while facing the chest wall of the patient, and wherein the flexible mounting element is configured to be bent to position the RF coil adjacent to the patient; and
an adjustment device positioned adjacent the flexible mounting element, and configured to bend the flexible mounting element to conform to the body of the patient adjacent the breast, wherein the adjustment device is coupled to a vertical track and is configured to move along the vertical track.
8. The coil array as recited in claim 7 , wherein the flexible mounting element includes a generally flat flexible portion adjacent the rigid cup-shaped element.
9. The coil array as defined in claim 7 , wherein the adjustment device is receivable in a patient support structure and is configured to move laterally along a lateral track provided in the patient support structure.
10. The coil array as defined in claim 7 , wherein the flexible mounting element is comprises a material that can be bent into and retain a position adjacent an anatomy of interest in the patient.
