Autor: C. Scherer, E. Semar, W. Wittwer, J. Wolthaus, T. Scherer

Publikováno v: Challenging Glass Conference Proceedings, Vol 5 (2016)

For the use in structural glazing (SSG) applications a new generation of warm edge system has been developed. This new technology is a spacer system based on polyisobutylene, especially designed for silicone sealed units, which replaces the conventio

Effects of Respiration-Induced Density Variations on Dose Distributions in Radiotherapy of Lung Cancer

Autor: Jan-Jakob Sonke, Eugène M.F. Damen, Marcel van Herk, Vanessa Mexner, J. Wolthaus

Publikováno v: International journal of radiation oncology, biology, physics, 74(4), 1266-1275. Elsevier Inc.

PURPOSE: To determine the effect of respiration-induced density variations on the estimated dose delivered to moving structures and, consequently, to evaluate the necessity of using full four-dimensional (4D) treatment plan optimization. METHODS AND

On-the-fly motion-compensated cone-beam CT using an a priori model of the respiratory motion

Autor: Simon Rit, Marcel van Herk, J. Wolthaus, Jan-Jakob Sonke

Publikováno v: Medical Physics. 36:2283-2296

Respiratory motion causes artifacts in cone-beam (CB) CT images acquired on slow rotating scanners integrated with linear accelerators. Respiration-correlated CBCT has been proposed to correct for the respiratory motion but only a subset of the CB pr

Purpose To discuss planning target volumes (PTVs) based on internal target volume (PTV ITV ), exhale-gated radiotherapy (PTV Gating ), and a new proposed midposition (PTV MidP ; time-weighted mean tumor position) and compare them with the conventiona
