Improved setup and positioning accuracy using a three‐point customized cushion/mask/bite‐block immobilization system for stereotactic reirradiation of head and neck cancer
TLDR
The use of image guidance for online setup correction, in combination with the customized CMB device, highly restricted target motion during treatments and provided robust immobilization to ensure minimum dose of 95% to target volume with 2.0 mm PTV margin for HN‐SABR.
Accuracy and precision of in vitro volumetric measurements by three-dimensional sonography.
TLDR
The accuracy and precision of volume estimates via three-dimensional ultrasound is at least as good as those obtained via conventional ultrasound.

Photon caliper to achieve submillimeter positioning accuracy.
TLDR
It is demonstrated that the VPF test can determine the offset between a 2D detector array and the radiation isocenter with submillimeter accuracy, until now, no method to locate the radiationIsocenter using a two-dimensional detector array has been able to achieve such accuracy.

TLDR
This study verified the VPF as a non-imaging method to localize the radiation isocenter with submillimeter accuracy and showed it to be feasible in the vertical direction as well.
New Progressive Addition Lens Design: Utilizing the Varilux Ipseo Lens for Non-Adapt PAL Wearers
TLDR
This paper explores different PAL designs and discusses which lens may benefit different individuals and gives patients having a hard time adapting to other PAL designs the opportunity to wear a PAL sucessfully.
