We describe a prototype digital radiotherapy simulator which consists of a conventional simulator gantry, digital spot imager, and image correction and reconstruction software. The ability of the digital spot imager to acquire a diagnostic quality image directly in digital format during simulation offers unique possibilities in clinical practice. Applications include prescription of multileaf collimator, on-line patient setup verification, remote consultation and treatment planning. In addition, we discuss the possibility of using the digital simulator as a volume-CT scanner capable of obtaining three-dimensional anatomical information in a single scan.
我们描述了一种原型数字放射治疗模拟器,它由传统的模拟器机架、数字点成像仪以及图像校正和重建软件组成。数字点成像仪在模拟过程中能够直接以数字格式获取具有诊断质量的图像,这在临床实践中提供了独特的可能性。其应用包括多叶准直器的处方、在线患者摆位验证、远程会诊和治疗计划。此外,我们还讨论了将数字模拟器用作容积CT扫描仪的可能性,该扫描仪能够在单次扫描中获取三维解剖信息。
