CIRSMRI-LINACDynamicPhantom專為端到端調(diào)試,混合MRI-LINAC放射治療系統(tǒng)的機器QA以及門控和適應(yīng)性治療計劃的驗證而設(shè)計。
CIRS008MMRI動態(tài)模體,CIRS008M模體型提供了評估MRI圖像質(zhì)量的手段,并且可以測試腫瘤定位和動作捕捉設(shè)備?;糜翱捎糜讷@取移動或靜態(tài)目標(biāo)圖像進(jìn)行門控或適應(yīng)性治療實施的治療計劃和驗證。

008M模體帶有目標(biāo)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(zhì)量。MRI-LINACDynamicPhantom利用CIRS運動控制軟件提供精確,可重復(fù)的3D目標(biāo)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(biāo)的移動桿。外殼內(nèi)充滿專有的MRI信號生成凝膠,可以快速輕松地進(jìn)行幻像設(shè)置,而不會產(chǎn)生液體運動偽影?;糜败嚿響覓煸诜谴跑壣?,可以進(jìn)行線圈定位和虛擬注冊到沙發(fā)上。
CIRS008MMRI動態(tài)模體,CIRS008M模體含有MRI質(zhì)量保證目標(biāo),與ACR認(rèn)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(biāo)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(biāo)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(cè)上為MRI/
CT目標(biāo)和MRI失真柵格加工出激光標(biāo)記。為了促進(jìn)MRI/
CT圖像融合,存在與外部激光標(biāo)記對準(zhǔn)的中心基準(zhǔn)點,并且在關(guān)于3D空間畸變網(wǎng)格的已知位置。
CIRS008MMRI動態(tài)模體,CIRS008M模體特征:
MRI-CT-LINAC兼容
3D目標(biāo)運動
門控和自適應(yīng)RT計劃驗證
