Stereotactic Dose Verification Phantom

Ion chamber and film dose measurements in a water-equivalent phantom designed specifically for stereotactic radiosurgery and recommended by Accuray.

Film Dosimetry Measurements


Five water equivalent Blue Water slabs allow film to be positioned 2 mm apart for dose profile measurements of very small SRS targets. A cavity in each slab positions a 2.5 x 2.5 inch film in the exact center.


Ion Chamber Measurements


The 2 cm Blue Water ion chamber slab has an SDVP Plug with a cavity drilled to accommodate inter-changeable ion chamber plugs, and positions the detector in the exact center of the phantom to facilitate repositioning and fast, accurate measurements.

Standard configuration of the Stereotactic Dose Verification Phantom includes the Film Dosimetry and Ion Chamber Measurement slabs.

For rigorous testing and evaluation of imaging, treatment planning, and dose conformity.


The optional SRS Dosimetric QA Slab provides complex geometric targets to evaluate the imaging components of your treatment planning system. Five CT densities are available for a QA check of the CT density model.

The optional SDVP Heterogeneity insert consists of two 5cm slabs, and a 2 cm chamber slab, each made of lung equivalent material. The lung-equivalent assembly is placed between the Stereotactic Dose Verification Phantom Blue Water Slabs. The Heterogeneity Insert Plug with gold fiducial markers is designed to simulate a small tumor within the lung-equivalent material.


Use the Exradin W1 Scintillator or other detector to perform small field tests in a highly heterogeneous environment. Included Extension Posts provide seamless integration with the Stereotactic Dose Verification Phantom for Monte Carlo dose verification.

Perform patient-specific QA for Accuray’s CyberKnife™ Radiosurgery System with ease.


The Stereotactic Top Hat makes fiducial Skull Tracking™ with the SDVP possible. Containing fiducials that appear on DRRs, the Stereotactic Top Hat allows for logical alignment and use of the pre-treatment imaging system. For additional convenience, use the Stereotactic Cradle to elevate the SDVP phantom above the treatment couch to avoid triggering collision errors.
