word-wrap: break-word !important; background-color: rgb(255, 255, 255);">质子重离子治疗要实现适形治疗,就需要高效地控制束流的横向位置、纵向的能量分布,以精准地匹配病灶的形状,这就需要能够±180°旋转、等中心点位置精度极高(理想的精度误差小于1mm)的旋转机架,来实现任意角度的供束。特别在重离子这一领域,目前只有德国海德堡离子治疗中心(HIT)使用了高精度的重离子治疗用旋转机架,但是国内进口就面临着巨额的购入成本和维护成本,因此国产自主研发是解决高昂成本的最好路径,国内除旋转机架以外的其他部件开发都相对成熟。此次上海庆强实业有限公司、上海理工大学、中国航天科工集团上海浦东开发中心自主研发成功了高精度、高稳定性、高性价比的质子治疗装置360°旋转机架,位置精度达到了&lt;1mm,破解了质子重离子束用于实体瘤的精准治疗的核心技术和工程难题,为“健康中国”的建设提供了科技支撑。</p><p style="max-width: 100%;
