Versatile Stereotactic QA

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

SDVP Heterogeneity Insert

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.
