Objectives: This study aimed to conduct a warm-up (W-up) program incorporating movement preparation (MP) and clarify its effect on sports injury prevention. Methods: The subjects of the study were 55 first- to third-year students (age: 15.9 ± 1.0 years, height: 168.5 ± 5.2 cm, weight: 57.4 ± 5.3 kg) belonging to a high school boys' soccer team. The first two months were the control period (CP), and the next two months were the intervention period (IP). The CP was a conventional W-up and the IP was a W-up with MP. The effects of each W-up were compared in terms of the incidence of sports injuries and disabilities during both periods and the incidence of sports injuries and disabilities by cause. Other measurements were compared for a total of seven items, including flexibility, balance, and performance. Results: During the IP, the incidence of sports injuries during practice and the incidence of non-contact sports injuries were reduced, whereas flexibility, balance, and performance improved. Conclusions: W-up incorporating MP showed improvement in flexibility and related balance, which may have led to the reduction of sports injuries.

Prompt gamma detection for range verification in proton therapy

It is an on-going challenge to verify the proton range in situ during proton therapy. Since the protons stop in target tissue, measurement of gamma-rays emitted either promptly from nuclear de-excitation or in pair from positron annihilation is the feasible method to monitor the proton range in-vivo. Using the technique of gamma collimation, we empirically demonstrated that the proton range and prompt gamma distribution are well correlated in the therapy energy range, and that measuring prompt gammas is a viable method for the clinical application. However, this collimation technique appears not to be applicable to passively scattered proton beams. The device chosen for gamma imaging in 2D is an electron tracking Compton camera, which images single-emission photons employing a gas chamber to induce Compton scattering. Images of prompt gammas were attained at the proton beam energy of 140 MeV. Measurements showed that gamma image in the energy range of 800e2000 keV provides a better match with the proton range compared to the image by lower energy gammas.

The purpose of this study is to develop the treatment planning system (TPS) based on Monte-Carlo simulation for BNCT. In this paper, we will propose a method for dose estimation by Monte-Carlo simulation using the CT image, and will evaluate the accuracy of dose estimation of this TPS. The complicated geometry like a human body allows defining using the lattice function in MCNPX. The results of simulation such as flux or energy deposition averaged over a cell, can be obtained using the features of the tally provided by MCNPX. To assess the dose distribution and therapeutic effect, dose distribution was displayed on the CT image, and dose volume histogram (DVH) was employed in our developed system. The therapeutic effect can be efficiently evaluated by these evaluation tool. Our developed TPS could be effectively performed creating the voxel model from CT image, the estimation of each dose component, and evaluation of the BNCT plan.
