美國CIRS 04a前列腺超聲模體主要用于前列腺超聲波測試。

美國CIRS 04a前列腺超聲模體產(chǎn)品簡介：

A robust quality assurance prostate brachytherapy QA program is essential to ensure accurate image-guidance and dosimetry calculations. The CIRS Model 04a, 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 04a 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.
