Particle radiotherapy with carbon ion beams [PDF]

EPMA Journal, 2013
Carbon ion radiotherapy offers superior dose conformity in the treatment of deep-seated malignant tumours compared with conventional X-ray therapy. In addition, carbon ion beams have a higher relative biological effectiveness compared with protons or X-ray beams. The algorithm of treatment planning and beam delivery system is tailored to the individual

Respiration-gated fast-rescanning carbon-ion radiotherapy [PDF]

Japanese Journal of Clinical Oncology, 2016
Phase-controlled rescanning of the carbon-ion beam offers fast and precise dose application with decreased irradiation of normal tissue. However, organ movement with respiration remains a unique challenge. Technological development has enabled the simultaneous application of beam-energy-modulated markerless phase-controlled rescanning with respiration ...

Evaluation and implementation of an independent Kilovoltage X-ray-based imaging platform for carbon ion radiotherapy. [PDF]

J Appl Clin Med Phys
Abstract Background Image‐guided particle therapy (IGPT) has significantly advanced in recent years, particularly in the context of proton therapy. However, imaging solutions for carbon‐ion radiotherapy (C‐ion RT) remain limited. Purpose This study introduces sliding‐gantry cone‐beam computed tomography (CBCT) and dual‐panel digital radiography (DR ...
