Abstract
An ultrasound imaging probe suitable for concentric on-axis biopsy procedures. The probe according to the present invention includes an aperture through which a biopsy needle is inserted to sample a target tissue previously located by the ultrasound probe. In operation, the ultrasonic probe is first positioned on the subject over a target tissue. A cursor is moved to visually overlap the target tissue within the subject, and the depth is indicated on a corresponding display. A biopsy needle is selected and adjusted to extend to the indicated depth when inserted through the ultrasonic probe and transducer aperture into the subject. Thus the apparatus according to the present invention provides for the improved biopsy procedures through the use of a probe having a needle entranced through the source aperture, used for imaging, thus minimizing risk and error arising from conventional off-axis needle entrances.
