Ion chamber and film dose measurements in a water-equivalent phantom designed specifically for stereotactic radiosurgery
The Stereotactic Dose Verification Phantom provides dose measurements for commissioning treatment systems, such as Accuray CyberKnife®, and specific plan dose verification. With just one phantom, use film, ion chambers and the unique SRS Dosimetric QA Slab to perform fast and accurate system evaluation.
The standard phantom is 20 x 20 x 10 cm in size, comprised of two 4 cm top and bottom build-up slabs, and two interchangeable 2 cm test inserts in the center. Optional inserts include the SRS Dosimetric QA Slab and SDVP Heterogeneity insert. Rigid alignment posts ensure phantom configurations are precisely repositioned, and thumb or
flat-head screws secure the phantom together for repeatable results. The Stereotactic Dose Verification Phantom is constructed of Blue Water material and additional slabs are available in many thicknesses for increased build-up
Built With Precision
Laser alignment lines are provided to accurately position the phantom for CT scans and for treatment. Gold and lead fiducial markers are located throughout the phantom for additional orientation and positioning accuracy. Distance measurements within the CT scanning and TPS can be verified with confidence.
