ABSTRACT:
An ultrasound phantom is provided which simulates human tissue containing tissue masses viable for biopsy. The phantom is used to demonstrate or teach the performance of a biopsy procedure assisted by real-time ultrasonic imaging. The phantom comprises a plurality of small balloons, filled with a viscous substance, and tied shut. The balloons are distributed through and surrounded by a gelatinous substance comprising tissue equivalent material. During a simulated biopsy procedure, a section of the phantom is imaged as a biopsy needle penetrates through the tissue equivalent material, pierces one of the balloons, and aspirates some of the viscous substance from the balloon.
