conform the isodose to irregular surfaces, not possible
with orthovoltage photons or electrons .
•
Full-scalp irradiation results in lower risk of excessive
brain irradiation compared with external beam
irradiation

The optimization techniques result in superior dose
uniformity at the prescription depth with HDR surface
applicators
•
The occupation time of the accelerators can be
