Online Adaptive Replanning Method for Prostate Radiotherapy

International Journal of Radiation Oncology Biology Physics, 2010
To report the application of an adaptive replanning technique for prostate cancer radiotherapy (RT), consisting of two steps: (1) segment aperture morphing (SAM), and (2) segment weight optimization (SWO), to account for interfraction variations.The new "SAM+SWO" scheme was retroactively applied to the daily CT images acquired for 10 prostate cancer ...

ART2Dose: A comprehensive dose verification platform for online adaptive radiotherapy

Medical Physics, 2023
AbstractBackgroundOnline adaptive radiotherapy (ART) involves the development of adaptable treatment plans that consider patient anatomical data obtained right prior to treatment administration, facilitated by cone‐beam computed tomography guided adaptive radiotherapy (CTgART) and magnetic resonance image‐guided adaptive radiotherapy (MRgART).

Validation of an online replanning technique for prostate adaptive radiotherapy

Physics in Medicine and Biology, 2011
We have previously developed an online adaptive replanning technique to rapidly adapt the original plan according to daily CT. This paper reports the quality assurance (QA) developments in its clinical implementation for prostate cancer patients. A series of pre-clinical validation tests were carried out to verify the overall accuracy and consistency ...

On the accuracy of bulk synthetic CT for MR-guided online adaptive radiotherapy

La radiologia medica, 2019
MR-guided radiotherapy (MRgRT) relies on the daily assignment of a relative electron density (RED) map to allow the fraction specific dose calculation. One approach to assign the RED map consists of segmenting the daily magnetic resonance image into five different density levels and assigning a RED bulk value to each level to generate a synthetic CT ...

Online dose-adaptive radiotherapy considerably reduces irradiated volume in rectal cancer radiotherapy

Radiotherapy and Oncology
Online adaptive radiotherapy (OART) allows for a reduction of geometric uncertainties and therefore smaller PTV margins. In this work we take the next step and introduce online dose-adaptive radiotherapy (DART), where the treatment plan is adapted not only to the geometry of the day but also to the accumulated dose delivered in previous fractions.14 ...

Online adaptive radiotherapy of the bladder: Small bowel irradiated-volume reduction

International Journal of Radiation Oncology*Biology*Physics, 2006
To assess the potential reduction of small bowel volume receiving high-dose radiation by using kilovoltage X-ray cone beam computed tomography (CBCT) and quantized margin selection for adaptive bladder cancer treatment.Twenty bladder patients were planned conformally using a four-field, 15-mm uniform margin technique.

Evaluation of set-up position changes during the online adaptive radiotherapy

Medical Dosimetry
This study aimed to assess intrafractional positional shifts occurring during cone-beam computed tomography (CBCT)-based online adaptive radiotherapy (oART) using the Varian Ethos system. Specifically, we quantified these positional deviations and examined their relevance for planning target volume (PTV) margin definition in the absence of pretreatment
