Model 045 Brachytherapy QA Phantom
Perform QA on sidefire transrectal probes.
Model 045 - Reliable and Specific:
The CIRS series of ultrasound phantoms,
unlike human subjects or random scannable
materials, offer a reliable medium which
contains specific, known test objects for
repeatable qualitative assessment of
ultrasound scanner performance over time.
The Model 045 was designed for transrectal
ultrasound QA and calibration of brachytherapy systems. It contains targets to assess volume
measurements, internal grid accuracy, and probe retraction accuracy. When scanning towards the
top of the phantom, a partial grid of wires appears. These wires should line up with the grid that
appears on your screen thus ensuring correct vertical and horizontal distance measurements.
Five cross wires are embedded within the Model 045 phantom to determine
if the probe is being retracted the specified distance. Turn the probe 60º to the right or left to
visualize and measure the volume of three different calibrated objects, one of which is non-spherical.
- Internal grid assessment
- Probe retraction step assessment
- Volume verification
