Charged particle beam radiotherapy requires dedicated measures to compensate for the
dosimetric influence of inter-and intra-fractional target motion. Independent of the delivery …

The development of positron emission tomography/computed tomography (PET/CT)
scanners has allowed not only straightforward but also synergistic fusion of anatomical and …

Purpose: Task Group (TG) 224 was established by the American Association of Physicists in
Medicine's Science Council under the Radiation Therapy Committee and Work Group on …

The physical characteristics of proton beams are appealing for cancer therapy. The rapid
increase in operational and planned proton therapy facilities may suggest that this …

This review considers the management of motion in photon radiation therapy. An overview is
given of magnitudes and variability of motion of various structures and organs, and how the …

The first patients were treated with proton beams in 1955 at the Lawrence Berkeley
Laboratory in California. In 1970, proton beams began to be used in research facilities to …

Clinical outcomes of charged particle therapy are very promising. Currently, several
dedicated centers that use scanning beam technology are either close to clinical use or …

In radiotherapy, the position of thoracic-abdominal tumor is changing due to respiratory
motion. Real-time tracking of thoracic-abdominal tumors is of great significance in improving …

Purpose: Motion interplay can affect the tumor dose in scanned proton beam therapy. This
study assesses the ability of rescanning and gating to mitigate interplay effects during lung …

Movement of tumours, mostly by respiration, has been a major problem for treating lung
cancer, liver tumours and other locations in the abdomen and thorax. Organ motion is …
