组建工程中心的背景与意义
放射诊断与放射治疗设备是医疗器械中技术含量和技术水平最高的设备领域之一,基本代表的医疗器械的技术水平,是最有前途的医疗器械产业之一,同时与诸多高新技术产业有关联,对未来的社会和经济具有举足轻重的意义。
与有关企业合作共同开展:①数字化X 射线机的平板探测器、高频高压发生器和X 射线球管三大核心部件;② 用于口腔、乳腺、关节等成像的专科CT 机的关键技术和整机开发。攻克数字化X 射线机的关键技术并实现产业化,从根本上解决各类数字X 线机和图像引导放疗等大型数字化医疗设备的关键核心部件国产化问题,提升民族企业在高端医学成像技术领域的水平,大幅度降低设备制造成本,改善我国基层医疗器械装备现状,降低患者就医成本,缓解看病贵、看病难的问题。
自主开发的基于平板探测搭建的Table-CT实验系统,可开展CBCT等成像关键技术的研究(发明专利:ZL201210425778.8)
在放射治疗技术与设备方面,恶性肿瘤是危害人类健康的第二大疾病,约有70%的患者在治疗的不同阶段需要接受放射治疗。
放射治疗的发展历史已有100 多年,随着医学技术的快速发展,放疗技术获得了前所未有的进步,放射治疗进入了现代放疗的全新时代。放射治疗设备属于大型高技术设备,价格昂贵,各级医院主要依赖于进口,国产放疗设备的技术性能与进口产品相比尚有较大差距,严重制约了放射治疗的普及应用,也加重了患者的负担。通过工程中心的建设,在攻克共性关键技术的基础之上,开发具有自主知识产权的放射治疗计划系统,同时,配合我省质子放射治疗系统的开发和产业化,开发用于质子治疗的放射治疗计划和图像引导系统,大幅度降低设备制造成本,降低患者就医成本。
