Advantages of HDR BT - I
•
Radioprotection is complete; isolation is not required
•
The moulds and surface applicators are easy to place and
patients do not report discomfort and the treatment is
administered on an outpatient basis, unlike interstitial
implant patients.
•
The dose distribution on the skin surface with contact
HDR-BT shows a sharp gradient, similar to the
conventional low-energy X-ray, in contrast to the
electron dose distribution. This gradient allows a higher
dose to the first mm and lower dosis to the deeper
tissues.
