cirs 008m mri动态模体，cirs 008m模体图像采集，治疗计划，剂量输送
cirs mri-linac dynamic phantom专为端到端调试，混合mri-linac放射治疗系统的机器qa以及门控和适应性治疗计划的验证而设计。cirs 008m mri动态模体，cirs 008m模体型提供了评估mri图像质量的手段，并且可以测试肿瘤定位和动作捕捉设备。幻影可用于获取移动或静态目标图像进行门控或适应性治疗实施的治疗计划和验证。cirs 008m mri动态模体，cirs 008m模体带有目标和延伸的刚性轴连接的模体，移动杆对于1.5t磁体是mri安全的。电机和运动控制器电子元件位于离磁铁安全距离处，以确保mri图像质量。mri-linac dynamic phantom利用cirs运动控制软件提供精确，可重复的3d目标运动。幻影体在大小和形状上逼近平均人体。它由带有圆柱形通孔的塑料外壳组成，以容纳具有模拟目标的移动杆。外壳内充满专有的mri信号生成凝胶，可以快速轻松地进行幻像设置，而不会产生液体运动伪影。幻影车身悬挂在非磁轨上，可以进行线圈定位和虚拟注册到沙发上。
cirs 008m mri动态模体，cirs 008m模体含有mri质量保证目标，与acr认证计划的建议相符：mri图像空间失真mri场均匀性激光到iso中心重合带有模拟目标的活动插件是一个密封的圆柱形杆，其填充了与幻像体相同的mri信号生成专用凝胶。嵌入式mri / ct靶由mri凝胶制成，可提供与背景相对的对比度。该目标可以接收离子室或其他mri兼容剂量计用于治疗剂量验证。在mri壳体的外侧上为mri / ct目标和mri失真栅格加工出激光标记。为了促进mri / ct图像融合，存在与外部激光标记对准的中心基准点，并且在关于3d空间畸变网格的已知位置。cirs 008m mri动态模体，cirs 008m模体特征：mri-ct-linac兼容3d目标运动门控和自适应rt计划验证端到端调试mri qaimage acquisition, treatment planning, dose deliverythe cirs mri-linac dynamic phantom is designed for end-to-end commissioning, machine qa for hybrid mri-linac radiation therapy systems, and verification of gated and adaptive treatment plans.the model 008m provides a means to assess mri image quality, and to test tumor localization and motion-capturing devices. the phantom can be used to acquire moving or static target images for treatment planning and verification of gated or adaptive treatment delivery.the phantom body, moving rod with target and extended rigid shaft connection are mri-safe with 1.5t magnets. motors and motion controller electronics are located at a safe distance from the magnet to ensure mri image quality. the mri-linac dynamic phantom utilizes cirs motion control software to provide precise, repeatable 3d target motion.the phantom body approximates an average human body in size and shape. it is comprised of a plastic shell with a cylindrical thru hole to accommodate a moving rod with simulated target. the shell is filled with proprietary mri signal-generating gel that allows for quick and easy phantom set-up without liquid motion artifacts. the phantom body is suspended on non-magnetic rails that allow for coil positioning and phantom registration to the couch.model 008m contains mri qa targets that are compatible with acr accreditation program recommendations for:mri image spatial distortionmri field homogeneitylaser to iso center coincidencethe moving insert with simulated target is a sealed, cylindrical rod filled with the same mri signal-generating proprietary gel as the phantom body. the embedded mri/ct target is made of mri gel that provides contrast with respect to the background. this target can receive an ion chamber or other mri-compatible dosimeters for treatment dose verification. there are laser marks machined on the outside of mri shell body for both the mri/ct target and mri distortion grid. to facilitate mri/ct image fusion, there is a central fiducial aligned with the exterior laser marks, and in a known position with respect to 3d spatial distortion grid.features:mri-ct-linac compatible3d target motiongated and adaptive rt plan verificationend-to-end commissioningmri qa
