Clinical radiotherapy procedures aim at high accuracy. However, there are many error
sources that act during treatment preparation and execution that limit the accuracy. As a …

Purpose: To compile and review data on the topic of organ motion and its management.
Methods and Materials: Data were classified into three categories:(a) patient position-related …

Purpose: Geometric uncertainties in the process of radiation planning and delivery constrain
dose escalation and induce normal tissue complications. An imaging system has been …

Purpose: Following the ICRU-50 recommendations, geometrical uncertainties in tumor
position during radiotherapy treatments are generally included in the treatment planning by …

Purpose Accurate target definition is critical for the appropriate application of radiation
therapy. In 2008, the Radiation Therapy Oncology Group (RTOG) published an international …
