TL;DR: This task group is charged with addressing the issue of radiation dose delivered via image guidance techniques during radiotherapy by compiling an overview of image-guidance techniques and their associated radiation dose levels to enable the design of image guidance regimens that are as effective and efficient as possible.

TL;DR: The target application of this paper is for radiotherapy treatment planning and evaluation that incorporates internal organ deformation throughout the course of radiation therapy and the registration method could also be equally applied in diagnostic radiology.

TL;DR: It was determined that helical tomotherapy is a system with some unique radiation characteristics, which have been to a large extent optimized for intensity modulated delivery.

TL;DR: The use of deformable image registration techniques and daily megavoltage computed tomography imaging makes it possible to calculate daily and accumulated dose-volume histograms and enable the implementation of dose-adaptive radiotherapy.

TL;DR: The stability of the MVCT numbers was tested by determining the variation of this CT to electron density calibration with spatial arrangement of the phantom, time and MVCT acquisition parameters and the Dosimetric differences observed in all phantom tests were within the range of dosimetric uncertainties observed due to variations in the calibration curve.
