We quantified dose variation effects due to respiratory-induced intrafractional motion in conventional carbon-ion prostate treatment by using four-dimensional computed tomography (4DCT). 4DCT scans of 20 patients were acquired under free-breathing co

Background and purpose To compare the efficacy and toxicity of short-course carbon ion radiotherapy (C-ion RT) for patients with hepatocellular carcinoma (HCC) in terms of tumor location: adjacent to the porta hepatis or not. Materials and methods Th

Purpose: When CT data with a thick slice thickness are used in treatment planning, geometrical uncertainty may induce dosimetric errors. We evaluated carbon ion dose variations due to different CT slice thicknesses using a four-dimensional (4D) carbo

Surgical resection is the standard treatment for stage I non-small cell lung cancer (NSCLC). However, elderly patients with NSCLC often suffer from other conditions, such as chronic obstructive pulmonary disease (COPD) or cardiovascular disease, and

We developed an algorithm which we used to design a compensating bolus by using respiratory-gated CT data for respiratory-gated carbon beam lung therapy and evaluated it by calculating dose distributions as a function of time. Four-dimensional CT (4D
