Dosimetry of Very-Small (5–10 mm) and Small (12.5–40 mm) Diameter Cones and Dose Verification for Radiosurgery with 6-MV X-Ray Beams

The dosimetry and dose verification for 6-MV X-rays were performed for radiosurgery cones of 5- to 40-mm diameter. The total scatter factors decrease slowly from 0.936 (40-mm cone) to 0.893 (10-mm con
