ABSTRACT:
The disclosed system (10) employs an MRI device to identify the location of an area of interest within a patient's breast (28) and guide a medical instrument (26) for insertion to the identified location. The patient (30) is positioned on a table top (18) having an opening (52) through which the patient's breast (28) pendulantly projects. The pendulant breast (28) is immobilized by a basket (36). The table top (18) and patient (30) are then introduced into magnetic field generator (12) and MRI signals are received by receiver (14). The location of an area of interest within the patient's breast (28) is determined based on the received signals. A guidance assembly (24) can then be used to aim the medical instrument (26) towards the location of interest via a penetration path selected so as to avoid the receiver (14) and basket (36).
