Abstract
Our institution established a new treatment facility for carbon ion beam scanning therapy in 2010. The major advantages of scanning beam treatment compared to the passive beam treatment are the following: high dose conformation with less excessive dose to the normal tissues, no bolus compensator and patient collimator/ multi‐leaf collimator, better dose efficiency by reducing the number of scatters. The new facility was designed to solve several problems encountered in the existing facility, at which several thousand patients were treated over more than 15 years. Here, we introduce the patient handling system in the new treatment facility. The new facility incorporates three main systems, a scanning irradiation system (S‐IR), treatment planning system (TPS), and patient handling system (PTH). The PTH covers a wide range of functions including imaging, geometrical/position accuracy including motion management (immobilization, robotic arm treatment bed), layout of the treatment room, treatment workflow, software, and others. The first clinical trials without respiratory gating have been successfully started. The PTH allows a reduction in patient stay in the treatment room to as few as 7 min. The PTH plays an important role in carbon ion beam scanning therapy at the new institution, particularly in the management of patient handling, application of image‐guided therapy, and improvement of treatment workflow, and thereby allows substantially better treatment at minimum cost.PACS numbers: 87.56.‐v; 87.57.‐s; 87.55.‐x
Highlights
227 Mori et al.: Patient handling system for carbon-ion scanning therapy treatment facility is designed to facilitate the integration of several systems with the overall goal of increasing treatment accuracy and improving treatment workflow in terms of their physical, technical, and clinical aspects
We previously developed a carbon ion accelerator which is approximately 60% smaller than that in our center, which is installed in Gunma University, Japan.[25]. Several solutions to these problems have been suggested, the most important of which involve improvements in treatment workflow and direct effects on cost reduction
This is important for particle therapy, as well as photon therapy now.[26]. In our center, more than 700 patients per year are treated by passive irradiation therapy over 4 days per week
Summary
227 Mori et al.: Patient handling system for carbon-ion scanning therapy treatment facility is designed to facilitate the integration of several systems with the overall goal of increasing treatment accuracy and improving treatment workflow in terms of their physical, technical, and clinical aspects. While the irradiation and treatment planning systems have been reported elsewhere,(3,4) the patient handling system (PTH) has not been described. We introduc the PTH in the new treatment facility at our center and describe its current status
