美国RSD RS-1500动态呼吸模体
动态呼吸模型(TBP)基于Alderson放射治疗(ART)模型。
呼吸模型中的软组织材料是用于ART模型的相同材料的弹性化版本。僵硬的骨头被结合并在模体中呼吸的动作下移动。弹性肺具有逼真的呼吸密度。
呼吸模体躯干模特是一种复杂的人形躯干模型,包括肺部,胸腔/胸壁骨骼,皮肤和亚表层,以及一个肺部体积内独立活动的肿瘤。在增加和减少气压的程序性应用下,模体肺填充和排空空气以复制人体肺功能。一厘米以上的胸部运动可以编程。随着肺部的扩张和收缩,模拟的胸腔骨骼像前部和前外侧皮肤表面一样移动。在将气压独立编程应用于多种工业标准气动执行机构之一的情况下,可实现一肺内的目标运动。模体的材料和成分被设计成忠实地模拟人体胸部的物理形态和放射影像特性。呼吸影像的呼吸相位门控计算机断层扫描显示它模拟人体胸部。
动态呼吸模体随RSD使用行业标准LabView™软件开发的控制软件交付。这确保了与不断发展的Microsoft Windows™计算机系统软件的兼容性。该软件通过通用串行总线(USB)与行业标准数据采集和控制模块进行通信。这些软件和控制组件的耐用和转让用户运行许可证随呼吸模型一起提供。

DYNAMIC ANATOMICAL RESPIRING HUMANOID PHANTOM
The dynamic breathing phantom (TBP) is based on the Alderson Radiation Therapy (ART) phantom.
The soft tissue materials in the breathing phantom are elasticized versions of the same materials refined for the ART phantom. Rigid bones are incorporated and move under the respiring motion in the phantom. The elastic lungs have realistic respiratory density.
The breathing phantom torso mannequin is a complex plastic simulation of a humanoid torso including lungs, ribcage/chest-wall bone, skin and sub-dermis, and an independently movable tumor within one of the lung volumes. Under the programmed application of increasing and decreasing air pressure, the phantom lungs fill and empty of air to replicate humanoid lung function. Chest movement of one cm and more can be programmed. As the lungs expand and contract, the simulated ribcage bones move as the anterior and antero-lateral skin surface. Under the independent programmed application of air pressure to one of several industry standard pneumatic motion actuators, target motion within one lung is accomplished. The materials and composition of the phantom are devised to be a faithful simulation of the physical form of a human thorax and to the radiological image properties. Respiration phase-gated computed tomography of the breathing phantom shows that it models the human thorax.
The Breathing Phantom is delivered with control software developed at RSD using industry standard LabView ™ software. This ensures compatibility with evolving Microsoft Windows ™ computer system software. The software communicates via Universal Serial Bus (USB) with an industry standard data acquisition and control module. Durable and transferred user run-time licenses for these software and control components are provided with the breathing phantom.
Independent motions are provided for lung and target waveform, phase, and rate.
