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.
