The Model 059 accurately mimics the ultrasonic characteristics of tissues found in an average human breast. The size and shape of the phantom simulates that of an average patient in the supine position.
A special holding tray facilitates proper hand position during the training procedures.
Protected by a membrane, the phantom’s Zerdine®¹ simulates needle resistance.
The phantom contains several solid masses that appear slightly hypoechoic to the simulated breast tissue under normal ultrasound, but the lesions are at least two times stiffer than the background so they can be detected on elastograms. Lesions range in size from 3 to 10 mm in diameter, are randomly positioned throughout the background, and can be biopsied 3 times.
