Image-Guided Abdominal Biopsy Phantom Model 071-A

Brand :

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 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.*

To accommodate image fusion techniques, CIRS can offer value added services such as phantom specific CMM, reference CT or MRI data sets, attachment of customer specific registration devices and inclusion of special point markers.

The phantom includes a foam lined hard carry case.


  • Improve performance of freehand abdominal biopsies
  • Test new equipment
  • Validate automated biopsy systems
  • Suitable for CT and ultrasound

* 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.
