Purpose CT ventilation image (CTVI)-guided radiotherapy that selectively avoids irradiating
highly-functional lung regions has potential to reduce pulmonary toxicity. Considering …

Purpose To compare helical tomotherapy (HT) and conventional intensity-modulated
radiotherapy (IMRT) using a variety of dosimetric and radiobiologic indexes in patients with …

To investigate the feasibility of lung ventilation-based treatment planning, computed
tomography and hyperpolarized (HP) helium-3 (He-3) magnetic resonance imaging (MRI) …

Purpose To compare the mid-position (MidP) strategy to the conventional internal target
volume (ITV) for lung tumor management in helical TomoTherapy, using 4D Monte Carlo …

Background Helical tomotherapy (HT) and volumetric modulated arc therapy (VMAT) are
both advanced techniques of delivering intensity-modulated radiotherapy (IMRT). Here, we …

Lung cancer treatment is one of the most challenging fields in radiotherapy. The aim of the
present study was to investigate what role helical tomotherapy (HT), a novel approach to the …

Background No selection criteria for helical tomotherapy (HT) based stereotactic ablative
radiotherapy (SABR) to treat early stage non-small cell lung cancer (NSCLC) or solitary lung …

Objective: To evaluate treatment outcomes and patterns of CT lung injury after
hypofractionated image-guided radiotherapy delivered with helical tomotherapy (HHT) in a …

Purpose: The gross tumor volume (GTV) for many lung cancer patients can decrease during
the course of radiation therapy. As the tumor reduces in size during treatment, the margin …

PURPOSE: To evaluate the impact of intra-fraction motion induced by regular breathing on
treatment quality for helical tomotherapy treatments. MATERIAL AND METHODS: Four …
