20. An investigation into the impact of volumetric rescanning and fractionation treatment on dose homogeneity in liver cancer proton therapy.

Abstract

The Pencil Beam Scanning (PBS) technique in modern particle therapy offers a highly conformal dose distribution but poses challenges due to the interplay effect, an interaction between respiration-induced organ movement and PBS. This study evaluates the effectiveness of different volumetric rescanning strategies in mitigating this effect in liver cancer proton therapy. We used a Geant4-based Monte Carlo simulation toolkit, 'TOPAS,' and an image registration toolbox, 'Elastix,' to calculate 4D dose distributions from 5 patients' four-dimensional computed tomography (4DCT). We analyzed the homogeneity index (HI) value of the Clinical Tumor Volume (CTV) at different rescan numbers and treatment times. Our results indicate that dose homogeneity stabilizes at a low point after a week of treatment, implying that both rescanning and fractionation treatments help mitigate the interplay effect. Notably, an increase in the number of rescans doesn't significantly reduce the mean dose to normal tissue but effectively prevents high localized doses to tissue adjacent to the CTV. Rescanning techniques, based on statistical averaging, require no extra equipment or patient cooperation, making them widely accessible. However, the number of rescans, tumor location, diaphragm movement, and treatment fractionation significantly influence their effectiveness. Therefore, deciding the number of rescans should involve considering the number of beams, treatment fraction size, and total delivery time to avoid unnecessary treatment extension without significant clinical benefits. The results showed that 2–3 rescans are more clinically suitable for liver cancer patients undergoing proton therapy. [ABSTRACT FROM AUTHOR]

28. The Determination of Virtual Source Position Using Poka-Yoke Concept to Minimize Mistakes for Scanning-Passive Scatter Beam in Carbon Ion Therapy.

Abstract

We developed a mistake-proofing technique (Poka-Yoke) capable of dealing with the virtual source position delivered by different carbon ion energies for scanning-passive scatter beam in carbon ion therapy. Despite a lot of methods that have been proposed for the determination of virtual source position for electron beam therapy in a linear accelerator and proton beams, none for heavy charged particles-like carbon ions have been investigated. The method can be also used for electron and the proton beams. [ABSTRACT FROM AUTHOR]
