Quantifying variability of intrafractional target motion in stereotactic body radiotherapy for lung cancers

Autor: Sherry C.Y. Ng, Eric W C Tam, Mark K.H. Chan, Dora L.W. Kwong, Anthony S. M. Tong

Publikováno v: Journal of Applied Clinical Medical Physics

In lung stereotactic body radiotherapy (SBRT), variability of intrafractional target motion can negate the potential benefits of four‐dimensional (4D) treatment planning that aims to account for the dosimetric impacts of organ motion. This study us

Accuracy and sensitivity of four-dimensional dose calculation to systematic motion variability in stereotatic body radiotherapy (SBRT) for lung cancer

Autor: Anthony S. M. Tong, Dora L.W. Kwong, Mark K. H. Chan, Sherry C.Y. Ng, Eric K. W. Tam

Publikováno v: Journal of Applied Clinical Medical Physics

The dynamic movement of radiation beam in real‐time tumor tracking may cause overdosing to critical organs surrounding the target. The primary objective of this study was to verify the accuracy of the 4D planning module incorporated in CyberKnife t

Experimental evaluations of the accuracy of 3D and 4D planning in robotic tracking stereotactic body radiotherapy for lung cancers

Autor: Mark K H, Chan, Dora L W, Kwong, Sherry C Y, Ng, Anthony S M, Tong, Eric K W, Tam

Publikováno v: Medical physics. 40(4)

Due to the complexity of 4D target tracking radiotherapy, the accuracy of this treatment strategy should be experimentally validated against established standard 3D technique. This work compared the accuracy of 3D and 4D dose calculations in respirat
