Product Description

A robust quality assurance prostate brachytherapy QA program is essential to ensure accurate image-guidance and dosimetry calculations. The CIRS Model 045A, used in conjunction with the CIRS Model 053G Ultrasound Prostate Phantom, 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 Model 045A enables users to check key imaging parameters such as depth of penetration, axial and lateral resolution, distance measurements, area measurements, volume measurements and geometric consistency with the treatment-planning computer.

When scanning towards the top of the phantom, a partial grid of wires appears. This N-shaped pattern should align with the electronic grid that appears on your screen to ensure correct vertical and horizontal distance measurements. This target group can also be used to assess axial and lateral resolution of the system. Five cross wires are embedded within the phantom to determine if the probe is being retracted by the stepper system by the specified distance.

Turn the probe 60 degrees to the right or left to visualize and measure the volume of three different calibrated objects, one of which is non-spherical.

  • QA assessments according to AAPM Task Group 1281:
    • Depth of penetration
    • Resolution
    • Distance, area and volume measurements
    • Geometric consistency
  • Foam-lined carry case
  • 48-month warranty


Complete your QA solution by also purchasing the Model 053S Ultrasound Prostate Phantom. The Model 053S can be used to verify alignment of the physical needle template with the electronic grid.
