ABSTRACT:
The advent of Intensity Modulated Radiation Therapy (IMRT) is rapidly
changing the field of Radiation Oncology. IMRT has the potential to improve
clinical implementation of highly conformal non-convex dose distributions.
Nonetheless, a number of IMRT approaches including coplanar and noncoplanar
beam techniques with 5 to 9 beams at different angles have been used in
an effort to get the best dose distribution. The purpose of this study is to
compare the dose to normal tissue and dose-limiting structures, conformity
index, homogeneity index, number of monitor units required for the treatment
of prostate cancer in 3 sets of five and seven beam IMRT plans and thus
to select the best IMRT approach for patients with prostate cancer.
