Image-Guided Abdominal Biopsy Phantom

Features:

• Improve performance of freehand abdominal biopsies
• Test new equipment
• Validate automated biopsy systems
• Suitable for CT, MRI and Ultrasound
• Country of Origin: United States of America

Model 071 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 allows 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, CT and MRI. The solid polymer gel background is anechoic and will not leak with punctured.*

A carry case is included.

Specifications:

• Dimensions: 4.9" L x 11" W x 7.9" H
• Material: Background: Zerdine®, 1550m/s (nominal) - Ribs & Vertebrae: Epoxy - Scan Surface: Urethane - Masses: Zerdine®, soft tissue
• Masses:
  
  • Large Mass: 25mm Diameter - Quantity: 1 - Positioned near vertebrae
  • Other Masses: 8-12 mm Diameter - Quantity: 11 - Randomly positioned in background

Any type of transducer can be used; the higher frequency transducer depth of penetration will make it hard to see the masses towards the center of phantom. The outer membrane is made of a thin plastic which is compatible with any transducer; coupling gel must be used.

*Some permanent tracking may be evident if debris and air bubbles are entrained in the gel during the biopsy procedure. To extend the lifetime of the phantom, the use of higher gauge needles that have been wetted and de-aired prior to insertion is recommended.
