Abstract
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).
Claims21
A system for performing an interventional breast procedure, the system comprising:
- a magnetic resonance scanner;
- a probe and a plurality of active probe tracking coils disposed with the probe such that a position and angulation of the probe is inferable from the tracked positions of the active probe tracking coils;
- a breast coil assembly configured to be disposed in an imaging region of the magnetic resonance scanner, the breast coil assembly including one or more active assembly tracking coils disposed with the breast coil assembly such that a position of the breast coil assembly is inferable from tracked positions of the one or more active assembly tracking coils;
- and
- a procedure controller which during performance of an interventional breast procedure (i) executes a magnetic resonance tracking sequence to determine tracked positions of the active probe tracking coils and one or more active assembly tracking coils, and (ii) determines position and angulation of the probe respective to the breast coil assembly based on the tracked positions.
An interventional breast procedure comprising:
- acquiring at least one magnetic resonance image of a breast using a breast coil assembly with one or more active assembly tracking coils positionally coordinated with the diagnostic image;
- inserting a probe into the breast;
- and
- tracking position and angulation of the probe at least during the inserting by iteratively executing a magnetic resonance tracking sequence to determine (i) tracked positions of a plurality of active probe tracking coils disposed with the probe and (ii) positions of the one or more active assembly tracking coils that are positionally coordinated with the diagnostic image.
