摘要： In an interventional breast procedure, a magnetic resonance tracking sequence (80) is executed to determine (i) tracked positions of a plurality of active probe tracking coils (50) disposed with a probe (42) of an interventional instrument (40) and (ii) tracked positions of one or more active assembly tracking coils (52) disposed with a breast coil assembly (20). A probe tip position and angulation respective to the breast coil assembly is determined (84) based on the tracked positions. Conformance with a probe trajectory (88) of the determined probe tip position and angulation respective to the breast coil is verified (92).
