CORE--COMPUTER CORE

计算机核心的作用是提供计算机资源--硬件， 软件和工作人员-这是所需要的各种研究项目， 整个项目的规划。 计算机核心目前的努力 以开发用于规划和交付的软件系统为中心 适形放射治疗 我们依次描述这些系统： 1)第一代三维放射治疗计划 （3DRTP）系统已在MSKCC开发，目前已进入临床 使用. 它使用户能够从一组输入的CT图像中勾勒出 感兴趣的结构，设置射束，执行剂量计算，以及 显示评估结果。 必要的附加功能 包括多叶准直的适形治疗计划目前 被纳入这个系统。 同时，我们正在开发一个 第二代系统具有许多新功能，将在 高性能RISC工作站。 2)计算机核心人员正在与Scanditronix合作开发 并改进软件，以便于提供计算机控制的， 节段性适形治疗，使用MM 50 Microtron。 计算机 核心软件系统（称为适形治疗验证、输送 CTVDR系统）将提供对患者数据库的访问 并与Scanditronix MM 50治疗软件进行通信， 提供治疗的机器参数，验证机器设置， 记录治疗。 患者设置和治疗的实际交付正在进行中 MM 50治疗软件的控制。 此外，我们还讨论了在计算机控制的辐射过程中患者的安全性 交付，特别是程序和系统保障措施， 以确保用于提供治疗的数据的完整性， 并防止在计算机控制的 动议 我们还描述了质量保证程序， 以上软件系统。

The role of the computer core is to provide computer resources - hardware, software and staff - that are needed by the various research projects and by the program project as a whole. Current efforts by the computer core center on the development of software systems for planning and delivering conformal radiation treatments. We describe each of these systems in turn: 1) A first generation three-dimensional radiation treatment planning (3DRTP) system has been developed at MSKCC and is currently in clinical use. It enables the user, from an input set of CT images, to outline structures of interest, set up beams, perform dose calculations, and display the results for evaluation. Additional features necessary for conformal therapy planning, including multileaf collimation, are presently being incorporated into this system. Concurrently, we are developing a second generation system with many new features, which will operate on high-performance RISC-based workstations. 2) The computer core staff is collaborating with Scanditronix to develop and improve software that will facilitate delivery of computer-controlled, segmental conformal treatments, using the MM50 Microtron. The computer core software system (called the Conformal Treatment Verification, Delivery and Recording, or CTVDR System) will provide access to the patient database and communicate with the Scanditronix MM50 Therapy Software to transmit machine parameters for delivering treatments, verify machine settings and record treatments. Patient setup and actual delivery of treatment is under the control of the MM50 Therapy Software. In addition we discuss patient safety during computer-controlled radiation delivery, in particular, the procedures and system safeguards that are to be implemented to ensure integrity of the data used to deliver treatments, and to protect against possible collisions during computer-controlled motions. We also describe quality assurance procedures with regard to the above software systems.
