The Treatment Process
Using AccuBoost Applicators
The dose delivered in this process is uniform, homogeneous and is accurately targeted to the breast tissue which, if left untreated, is the most likely sites for cancer recurrence.
Step 1: Target & Applicator Size Selection
The breast is slightly compressed (immobilized), then imaged to locate the lumpectomy cavity and determine the size and position of the applicator to be used for delivering the radiation.
Step 2: Vertical Treatment
Radiation is delivered from above and below.
Step 3: Horizontal Treatment
The breast is immobilized in a different (horizontal) orientation, an image is taken to locate the lumpectomy cavity and to select the applicator size, then radiation is delivered from both horizontal directions.
Step 4: Overlapping Treatment
The dose builds up to the desired level in the tissue where the two treatments overlap; everywhere else receives a lower dose.
