A tissue biopsy device uses ultrasonic imaging to guide the biopsy needle. An ultrasonic imaging device comprises three acoustically coupled chambers with an ultrasound transducer in a first chamber, at least a portion of an ultrasound detector in the second chamber and the portion of patient anatomy to be imaged placed in the third chamber, which is intermediate the first and second chambers. The three chambers are filled with an acoustically transmissive liquid. When a structure, such as a lesion, has been located, the imaging may be used to determine the precise location of the lesion in three dimensions. The ultrasonically transmissive fluid is drained from the central third chamber with ultrasonic coupling occurring through the ultrasonically transmissive compression plates and the imaged patient anatomy. This permits real-time imaging of the patient anatomy during the biopsy process. |
