The Model 071A Image-Guided Abdominal Biopsy Phantom is a simplified abdominal phantom suitable for training and demonstrating image-guided needle biopsy navigation tools or procedures that require a constant visual reference for needle placement. Because it is constructed of a self-healing formulation of Zerdine®, the phantom will allow multiple biopsy insertions with minimal needle tracking.
The phantom contains 11 randomly positioned lesions, with sizes ranging from 8 to 12 mm. It also includes simulated spine, ribs, and a 25 mm lesion near the vertebrae.
The lesions and spine are visible under ultrasound and CT. The solid polymer gel background is anechoic and will not leak when punctured.
