Imaging of the secondary electron bremsstrahlung (SEB) X-rays emitted during particle-ion irradiation is a promising method for beam range estimation. However, the SEB X-ray images are not directly correlated to the dose images. In addition, limited

We evaluated an estimation ability of shifts of therapeutic carbon-ion beams owing to cavities in a polyethylene target by measuring prompt X-rays emitted from beam trajectories. Carbon-12 beams having the energy of 241.5 MeV/u were irradiated on a p

Low-energy X-ray imaging of prompt secondary electron bremsstrahlung X-rays (prompt X-rays) emitted during particle-ion irradiation is a promising method for range estimation. However, measurements have so far been conducted mainly for uniform phanto

Publikováno v: Journal of Instrumentation (JINST). 16(1):P01004

Although light emission from an acrylic block during irradiations of carbon-ions lower energy than the Cerenkov-light threshold was found recently, the origins and fractions of the light in the images were not yet obvious. Since light spectra may pro

Publikováno v: Phys. Med. Biol.. 65(10):105008-105008-15

Low-energy X-ray imaging of secondary electron bremsstrahlung X-rays emitted during carbon-ion irradiation is a promising method for range estimation and could be used for imaging with almost clinical dose levels of carbon ion. However, the number of
