Technical considerations in B-mode scanning with an aspiration transducer.
Proper orientation of the B-mode ultrasonic aspiration transducer is important for accurate imaging during aspiration biopsy. The transducer extension axis must be perpendicular to the plane of the scanning arm for accurate representation of reflector locations. Single pass scans without compound angulation of the transducer are recommended when perpendicularity is not absolute. A simple adaptor to maintain perpendicularity is described.
