Clinical Radiation Physics Service

该科继续为放射治疗提供专家实物和技术支助，包括所有辐射生产和辅助设备的例行校准、质量保证和一线维护。它包括特殊剂量研究、计算机辅助治疗计划、患者监测以及为发展临床需求量身定做的特殊设备的设计和开发。二极管现已在临床上用于验证患者的剂量，其准确度为+/-3%。一个新的商业治疗计划系统(瓦里安·日月食)已经投入使用，并与新的记录和验证系统集成在一起，该系统具有先进的系统，能够控制动态调强放射治疗的交付，并为该部门提供基于DICOM-RT的图像管理系统。通过CRADA获得了一种新的Nucletron HDR高剂量率近距离放射治疗系统，具有单独的治疗计划，并已投入临床使用。最后，已经安装并启用了立体定向放射外科治疗计划系统的重大升级。科室搬迁到新的临床研究中心的计划已经完成，之后将对现有科室进行翻新，以建立ROMAT设施。已经招募了一名新的研究水平的生物物理学家，预计将于04年春季开始工作。

The section continues to provide expert physical and technological support for radiation treatment, consisting of routine calibration, quality assurance and first-line maintenance of all radiation producing and ancillary equipment. It includes special dosimetry studies, computer- assisted treatment planning, patient monitoring and the design and development of special equipment tailored to developing clinical needs. Diodes are now in routine clinical use for the verification of patient doses and exhibit an accuracy of +/- 3%. A new commercial treatment planning system (Varian Eclipse) has been commissioned and integrated with the new Record-and-Verify system which has advanced system capable of controlling the delivery of dynamic IMRT radiotherapy as well as providing the department with a DICOM-RT based image management system. A new Nucletron HDR high dose rate brachytherapy delivery system with separate treatment planning has been obtained through a CRADA and has been commissioned for clinical use. Finally, a significant upgrade to the stereotactic radiosurgery treatment planning system has been installed and commissioned. Planning has completed for the departmental move to the new Clinical Research Center, afterwiich the existing department will be rennovated to establish the ROMAT facility. A new research level biophysicist has been recruited and is expected to start in the Spring of "04.
