Clinical Radiation Physics Service

我们已经建立了常规动态调强放射治疗（dIMRT）。这是最复杂的调强放射治疗，需要大量的治疗前验证，以确保准确执行。这些治疗使用我们的双Clinac-21 EX加速器进行。移除低能量Clinac-600 C/D加速器，并更换为Tomotherapy Inc.。Hi-ART系统，用于通过螺旋断层治疗提供治疗。该系统为ROB提供了尖端的治疗技术，以支持未来的临床试验。断层治疗室还配置了我们的Nucletron高剂量率后装机（HDR），用于提供复杂的近距离放射治疗。该单位已获得适当的许可和重新采购，并在临床上运作。放射外科手术能力已转移到较旧的Clinac-21 EX，并已重新投入使用。该部门目前正在用新的Philips Brilliance 16层大口径CT模拟器替换Philips AcquSim CT模拟器。Varian Trilogy On-Board kV成像系统计划安装在较新的Clinac-21 EX上，Varian RPM呼吸门控系统正在实施，以提供门控放射治疗。呼吸门控将通过补偿治疗期间的规则呼吸运动来提高靶向能力。我们有一个新的物理学家来分担临床和研究工作。他在计算机应用和体绘制方面的广泛专业知识将被证明对分支的研究使命是无价的。他以前是我们分支的成像科学家，但接受过医学物理学培训，并成功完成了资格考试以获得认证。影像科学家的空缺将通过招聘来填补。我们还有一位博士后研究员，他也在接受医学物理学家的培训。他的研究主要是基于蒙特卡罗的辐射剂量学

We have instuted routine dynamic Intensity Modulated Radiation Therapy (dIMRT). This is the most complex of IMRT treatments and requires considerable pre-treatment verification to ensure accurate execution. These treatments are delivered using our twin Clinac-21EX acceleratrors. The low energy Clinac-600C/D accelerator was removed and replaced with a Tomotherapy Inc. Hi-ART system for delivering treatments via helical tomotherapy. This system provides ROB with cutting edge treatment technology to support future clinical trials. The Tomotherapy treatment room has also been configured for our Nucletron High Dose-Rate Afterloader (HDR) for delivering sophisticated brachytherapy treatments. The unit has been properly licensed and re-sourced and is clinically operational. Radiosurgery capability has been transferred to the older Clinac-21EX and has been recommissioned. The department is currently replacing their Philips AcqSim CT Simulator with a new Philips Brilliance 16 slice, large bore CT Simulator. The Varian Trilogy On-Board kV imaging system is scheduled to be installed on the newer Clinac-21EX and the Varian RPM Respiratory Gating system is being implimented to provide gated radiation therapy. Respiratory gating will improve targeting ability by compensating for regular respiratory motions during treatment. We have a new physicist to share clinical and research duties. His broad expertise in computer aplications and volume rendering will prove invaluable to the research mission of the branch. He was previously an imaging scientist in our branch, but trained in medical physics and successfully completed his qualifying examinations to obtain certification. The imaging scientist vacancy will be filled by recruitment. We also have a post doctoral fellow who is also training as a medical physicist. His research is principally in Monte Carlo based radiation dosimetry
