Clinical comparison of positional accuracy and stability between dedicated versus conventional masks for immobilization in cranial stereotactic radiotherapy using 6-degree-of-freedom image guidance system-integrated platform

A comprehensive evaluation of treatment accuracy, including end-to-end tests and clinical data, applied to intracranial stereotactic radiotherapy

“…In our current study, we assume the rotational error is either small enough to have no clinically relevant influence or will be corrected for, e.g., by using a 6D couch [30,31].…”

To frame or not to frame? Cone‐beam CT‐based analysis of head immobilization devices specific to linac‐based stereotactic radiosurgery and radiotherapy

“…While there exist a number of studies that have assessed the positional accuracy and stability of different invasive and noninvasive immobilization systems for cranial stereotactic radiotherapy,6, 9, 16, 17, 18, 19, 20 to our knowledge, no study has directly compared the performance of various systems used in the same institution.…”

Comparison of pencil beam–based homogeneous vs inhomogeneous target dose planning for stereotactic body radiotherapy of peripheral lung tumors through Monte Carlo–based recalculation

“…In clinical practice, we have routinely used several optimization techniques, including the use of modified PTV geometry as a surrogate for leaf fitting to improve dose conformity, and manual adjustment of the selected leaf positions to further sculpt dose distribution (e.g., mitigation of the dose hot area within the chest wall). 10,[31][32][33] Lastly, this was a planning study, and the results must therefore be validated through a prospectively designed clinical research.…”

“…6,10,12 Comparisons of paired and unpaired variables were performed using the Wilcoxon signed-rank test and Mann-Whitney U test, respectively. Spearman's rank correlation coefficient was used to evaluate any correlations between variables.…”
