图像采集,治疗计划,剂量输送
CIRSMRI-LINACDynamicPhantom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。
CIRS008MMRI动态模体,CIRS008M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。

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-LINACDynamicPhantom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。
CIRS008MMRI动态模体,CIRS008M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。
