BREAST ULTRASOUND PHANTOM, METHOD FOR PRODUCING BREAST ULTRASOUND PHANTOM, AND ACCOMMODATING BOX FOR ACCOMMODATING SAID BREAST ULTRASOUND PHANTOM

摘要

This phantom (10) is equipped with: a pectoralis major muscle simulation layer (21) that simulates the pectoralis major muscle of the human body in terms of the ultrasonic propagation characteristics; and a retromammary space fat simulation layer (22) that simulates the adipose layer of the retromammary space of the human body in terms of the ultrasonic propagation characteristics, the retromammary space fat simulation layer being layered on the pectoralis major muscle simulation layer. The phantom is also equipped with: a skin simulation layer (23) that simulates the surface skin layer of the breast in terms of the ultrasonic propagation characteristics; a subcutaneous fat simulation layer (24) that simulates the subcutaneous fat of the breast, the subcutaneous fat simulation layer being attached to the inside of the skin simulation layer; and a plurality of glandular lobe simulators (25) that simulate the glandular lobes of the breast at least in terms of the ultrasonic propagation characteristics, the glandular lobe simulators being arranged between the retromammary space fat simulation layer and the subcutaneous fat simulation layer. At least one lesion simulation portion (T1 (T2-T4)) that simulates a breast lesion in terms of the ultrasonic propagation characteristics is provided in the plurality of glandular lobe simulators (25).
