CIRSMRI-LINACDynamicPhantom專為端到端調試,混合MRI-LINAC放射治療系統的機器QA以及門控和適應性治療計劃的驗證而設計。
CIRS008MMRI動態模體,CIRS008M模體型提供了評估MRI圖像質量的手段,并且可以測試腫瘤定位和動作捕捉設備。幻影可用于獲取移動或靜態目標圖像進行門控或適應性治療實施的治療計劃和驗證。

008M模體帶有目標和延伸的剛性軸連接的模體,移動桿對于1.5T磁體是MRI安全的。電機和運動控制器電子元件位于離磁鐵安全距離處,以確保MRI圖
像質量。MRI-LINACDynamicPhantom利用CIRS運動控制軟件提供精確,可重復的3D目標運動。
幻影體在大小和形狀上逼近平均人體。它由帶有圓柱形通孔的塑料外殼組成,以容納具有模擬目標的移動桿。外殼內充滿專有的MRI信號生成凝膠,可以快速輕松地進行幻像設置,而不會產生液體運動偽影。幻影車身懸掛在非磁軌上,可以進行線圈定位和虛擬注冊到沙發上。
CIRS008MMRI動態模體,CIRS008M模體含有MRI質量保證目標,與ACR認證計劃的建議相符:
MRI圖像空間失真
MRI場均勻性
激光到ISO中心重合
帶有模擬目標的活動插件是一個密封的圓柱形桿,其填充了與幻像體相同的MRI信號生成專用凝膠。嵌入式MRI/
CT靶由MRI凝膠制成,可提供與背景相對的對比度。該目標可以接收離子室或其他MRI兼容劑量計用于治療劑量驗證。在MRI殼體的外側上為MRI/
CT目標和MRI失真柵格加工出激光標記。為了促進MRI/
CT圖像融合,存在與外部激光標記對準的中心基準點,并且在關于3D空間畸變網格的已知位置。
