Webcult to achieve for a plan with a high level of complexity. Complexity metrics are then based on identified sources of errors in IMRT/VMAT delivery (MLC leaf position, gantry rotation, beam stability) and treatment planning system (TPS) calculation (MLC modelling, off-axis and irreg-ular field modelling, output factors for small field sizes).5 WebDec 15, 2015 · Results: The SBRT–VMAT reconstruction model performed very well when compared to the TPS. A stringent 2%/2 mm χ-comparison calculation gave pass rates better than 91% for the prostate plans, 88% for the lung plans, and 86% for the spine plans for voxels containing 80% or more of the prescribed dose.
Webused 30 seconds for a plan generation in contrast to the current clinical practice (>20 minutes). Conclusion: Results suggest that AVP-DSP can generate a prostate VMAT plan … WebOct 4, 2024 · Abstract. To reduce the complexity associated with VMAT planning, we developed a model which can predict the dose volume histograms (DVHs) of organ-at-risk …

WebApr 13, 2024 · The gamma analysis metric is a commonly used metric for VMAT plan evaluation. The major drawback of this is the lack of correlation between gamma passing rates and DVH values. The novel GDSA mean metric was developed by Steers et al. to quantify changes in the PTV mean dose (D mean) for VMAT patients.
