Dosimetric endpoints were based on dose-volume histograms calculated from the CTref and the pCTs for various volumes of interest and on 3-dimensional gamma analyses. The PBM uncertainties were compared with those of the ABM and BDM. Results: The mean absolute error and mean error obtained from the PBM were 41.1 and –1.1 Hounsfield units. The PBM dose-volume histogram differences were 0.7% for prostate planning target volume V95%, 0.5% for rectum V70Gy, and 0.2% for bladder V50Gy. Compared with ABM and BDM, PBM provided significantly lower dose uncertainties for the prostate planning target volume (70-78 Gy), the rectum (8.5-29 Gy, 40-48 Gy, and 61-73 Gy), and the bladder (12-78 Gy). The PBM mean gamma pass rate (99.5%) was significantly higher than that of ABM (94.9%) or BDM (96.1%). Conclusions: The proposed PBM provides low uncertainties with dose planned on CTref. These uncertainties were smaller than those of ABM and BDM and are unlikely to be clinically significant.]]> Wed 23 Feb 2022 16:03:06 AEDT ]]> Pseudo-CT generation for MRI-only radiotherapy: comparative study between a generative adversarial network, a U-Net network, a patch-based, and an atlas based methods https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38715 Mon 20 Nov 2023 15:50:10 AEDT ]]> Pseudo-CT generation by conditional inference random forest for MRI-based radiotherapy treatment planning https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32135 Fri 04 May 2018 15:36:57 AEST ]]>
