Brachytherapy QA Phantom - Model 045A - Products - CIRS

Part of a complete solution as described by AAPM Task Group 128

A robust quality assurance prostate brachytherapy QA program is essential to ensure accurate image-guidance and dosimetry calculations. The CIRS Model 045A offers a complete solution for implementing a QA program specific to transrectal ultrasound used for guidance of prostate brachytherapy as recommended by AAPM Task Group 1281 .

The phantom is made of CIRS' proprietary Zerdine®(2) hydrogel polymer, which has been formulated to provide tissue mimicking properties including compatibility with harmonic imaging. To maximize phantom lifetime, this gel is contained in a rugged ABS plastic housing with a Saranbased laminate membrane.

CIRS Ultrasound QA phantoms come standard with a robust housing, rugged carry case, 48-month warranty and user’s guide.
