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， 确保准确执行。这些治疗使用我们的双胞胎Clinac-21 EX进行 加速器A Tomotherapy Inc Hi-ART系统，用于通过螺旋输送治疗 断层治疗已经安装、接受，目前正在治疗患者。该系统 为ROB提供尖端的治疗技术，以支持未来的临床试验。我们有 开始了一系列的倡议与我们的核高剂量率后装机（HDR），使用 用于间质和腔内近距离放射治疗的小型高强度192 Ir源。我们 通过购买3个新的施源器，扩大了放射外科手术能力， 直径为5 mm、7.5mm和10 mm。Philips Brilliance 16层大口径CT模拟机 已安装并投入使用。板载成像（OBI）已安装在较新的 Clinac-21EX。Varian RPM呼吸门控系统的最后一个组件， 门控放射治疗已经准备好了我们正在等待交货呼吸门控 将通过补偿呼吸过程中的规则呼吸运动来提高瞄准能力， 治疗我们有一个新的物理学家来分担临床和研究工作。他广博的专业知识 在计算机应用和体绘制将证明是无价的研究使命 分支。他以前是我们分支的成像科学家，但接受过医学培训， 并顺利通过资格考试获得证书。的 影像科学家的空缺由一名经验丰富的资深影像科学家填补。 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测定

We have institu8ed 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 accelerators. A Tomotherapy Inc. Hi-ART system for delivering treatments via helical tomotherapy has been installed, accepted and is currently treating patients. This system provides ROB with cutting edge treatment technology to support future clinical trials. We have started a series of initiatives with our Nucletron High Dose-Rate Afterloader (HDR) , using a small, high intensity 192Ir source for interstitial and intercavitary brachytherapy. Our radiosurgery capability has been expanded with the acquisition of 3 new applicators with diameters of 5mm, 7.5mm and 10mm. A new Philips Brilliance 16 slice, large bore CT Simulator has been installed and is operational. On-board imaging (OBI) has been installed on the newer Clinac-21EX. The final component of the Varian RPM Respiratory Gating system for providing gated radiation therapy has been acquired and we are awaiting delivery. 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 applications 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 was filled by a senior imaging scientist with extensive experience. 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
