Comparison of dose distribution in IMRT and RapidArc technique in prostate radiotherapy

Abstract

Analysis presented in this paper, demonstrated that RapidArc can compete with the IMRT technique in the field of treatment plan dosimetry reducing the time required for dose delivery.

Integral dose: Comparison between four techniques for prostate radiotherapy

“…ID is lower for higher energy beams, regardless of the technique (VMAT, IMRT). The results are consistent with the literature, 13 indicating a comparable dose distribution in the dynamic techniques (IMRT and VMAT) in radiotherapy of prostate cancer. Simultaneously Wilcoxon test showed that there is no difference between ID delivered to PTV for VMAT (X-6MV vs. X-20MV; p = 0.53) and for IMRT (6 MV vs. 20 MV; p = 0.2).…”

Volumetric modulated arc therapy for prostate cancer patients with hip prosthesis

“…The planning is quite simple and straightforward unlike in IMRT which requires multiple runs to achieve an acceptable dose distribution. VMAT is currently evolving as the most popular treatment modality due to shorter time 20 required to deliver treatment as compared to conventional 3D conformal radiotherapy and IMRT technique. This may also reduce a possible uncertainty in dose due to a setup error.…”

Stereotactic radiosurgery of prostate cancer – dose distribution for VMAT and CyberKnife techniques

“…Irradiation of patients using IMRT, VMAT, CK, and TT techniques is increasingly reported in the literature [16][17][18][19][20][21][22]. Despite the technological differences related to the geometry of generated beams: the changing shape of the beam field vs circular tubes, the dose distributions we obtain as a result of the calculations are very comparable, of course, for "small" cancerous changes.…”
