简介
Purpose
A practical method to achieve prostate immobilization and daily target localization for external beam radiation treatment is described.
Methods and Materials
Ten patients who underwent prostate brachytherapy using permanent radioactive source placement were selected for study. To quantify prostate motion both with and without the presence of a specially designed inflatable intrarectal balloon, the computerized tomography–based coordinates of all intraprostatic radioactive sources were compared over 3 consecutive measurements at 1-min intervals.
Results
The placement and inflation of the intrarectal balloon were well tolerated by all patients. The mean (range) displacement of the prostate gland when the intrarectal balloon was present vs. absent was 1.3 (0–2.2) mm vs. 1.8 (0–9.1) mm (p = 0.03) at 2 min respectively. The maximum displacement in any direction (anterior–posterior, superior–inferior …
