Quantitative evaluation of potential irradiation geometries for carbon‐ion beam grid therapy [PDF]

Medical Physics, 2018
PURPOSE Radiotherapy using grids containing cm-wide beam elements has been carried out sporadically for more than a century. During the past two decades, preclinical research on radiotherapy with grids containing small beam elements, 25 μm-0.7 mm wide ...

Experimental exploration of a mixed helium/carbon beam for online treatment monitoring in carbon ion beam therapy

Physics in Medicine & Biology, 2020
Recently, it has been proposed that a mixed helium/carbon beam could be used for online monitoring in carbon ion beam therapy. Fully stripped, the two ion species exhibit approximately the same mass/charge ratio and hence could potentially be accelerated

The GATE-RTion/IDEAL Independent Dose Calculation System for Light Ion Beam Therapy

Frontiers in Physics, 2021
Patient specific quality assurance can be improved using an independent dose calculation system. In addition, the implementation of such a system may support light ion beam therapy facilities in reducing the needs for beam time, by substituting some of ...

Modelling secondary cancer risk ratios for proton vs. carbon ion beam therapy: A comparative study based on the Local Effect Model.

Medical Physics (Lancaster), 2022
BACKGROUND Ion beam therapy allows for substantial sparing of normal tissues. Besides deterministic normal-tissue complications, stochastic long-term effects like secondary cancer (SC) induction are of importance when comparing different treatment ...

Dual‐layer spectral CT for proton, helium, and carbon ion beam therapy planning of brain tumors

Journal of Applied Clinical Medical Physics, 2021
Pretreatment computed tomography (CT) imaging is an essential component of the particle therapy treatment planning chain. Treatment planning and optimization with charged particles require accurate and precise estimations of ion beam range in tissues ...

A Beam Monitor for Ion Beam Therapy Based on HV-CMOS Pixel Detectors [PDF]

Instruments, 2022
Particle therapy is a well established clinical treatment of tumors. More than one hundred particle therapy centers are in operation world-wide. The advantage of using hadrons like protons or carbon ions as particles for tumor irradiation is the distinct
