During
an MR-guided breast intervention, placement of a needle or probe requires
accurate localization of the target. To allow rapid identification of these
errors, avoid unnecessary trauma to the patient, and minimize scanner time, a
real-time MR acquisition and display was implemented to allow the physician
to monitor both the progress of the insertion and the procedure itself, such
as core needle biopsy or tumor ablation. Flexibility was added to adjust the
scan plane in real-time and make tradeoffs between update display rate and
image quality.
