Integrated MR imaging and interventional coil device, method and system

摘要

MR imaging and intervention functions are localized within a single device. At least one integrated coil device (62,63,64,90) which has at least one RF coil (72,94,112,118), a housing (70,74,92,96,110,114) which encases the RF coil and provides an anatomically conformal surface, and a plurality of apertures. The integrated coil device slides along a guide rail system (66) to adjust the size of a patient anatomical imaging region (60). The apertures in the integrated coil device are available to secure tool holder grid plate inserts (67,116,130,131) or other interventional device guides. The inserts assist in holding the soft tissue for diagnostic imaging and provide support for biopsy/interventional instrument guides (140). The integrated MR imaging and interventional coil device works in combination with a prone patient support structure (20), an adaptive torso sling (55), and also features an open architecture design for improved patient access. The device also works for supine or side imaging procedures.

主权项

1. An integrated magnetic resonance (MR) imaging and interventional system comprising:
a support structure configured to be disposed in an MR examination space; at least one coil device disposed on the support structure and defining an anatomical imaging region therebetween, the at least one coil device being mounted to translate relative to the support structure to adjust a size of the anatomical imaging region, the at least one coil device including:
at least one radiofrequency (RF) coil element which induces MR and/or receives MR signals from the anatomical imaging region;a housing having conformal surface facing the anatomical imaging region, which conforms with a patient anatomical portion to be received in the anatomical imaging region, the housing encasing the at least one RF coil element; andwherein the at least one coil device defines at least one aperture in the conformal surface for accommodating a target block which defines a trajectory for an interventional device into the anatomical portion; andwherein the at least one coil device includes a lateral coil device and a medial coil device and an axilla coil and wherein the anatomical portion includes at least one of a patient breast and axilla region and the housing conformal surface is configured to conform at least one of the breast and the axilla region.
