CIRSMRI-LINACDynamicPhantom專為端到端調(diào)試，混合MRI-LINAC放射治療系統(tǒng)的機(jī)器QA以及門(mén)控和適應(yīng)性治療計(jì)劃的驗(yàn)證而設(shè)計(jì)。

CIRS008MMRI動(dòng)態(tài)模體，CIRS008M模體型提供了評(píng)估MRI圖像質(zhì)量的手段，并且可以測(cè)試腫瘤定位和動(dòng)作捕捉設(shè)備。幻影可用于獲取移動(dòng)或靜態(tài)目標(biāo)圖像進(jìn)行門(mén)控或適應(yīng)性治療實(shí)施的治療計(jì)劃和驗(yàn)證。

CIRS008MMRI動(dòng)態(tài)模體，CIRS 008M模體帶有目標(biāo)和延伸的剛性軸連接的模體，移動(dòng)桿對(duì)于1.5T磁體是MRI安全的。電機(jī)和運(yùn)動(dòng)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(yùn)動(dòng)控制軟件提供精確，可重復(fù)的3D目標(biāo)運(yùn)動(dòng)。

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(dòng)桿。外殼內(nèi)充滿專有的MRI信號(hào)生成凝膠，可以快速輕松地進(jìn)行幻像設(shè)置，而不會(huì)產(chǎn)生液體運(yùn)動(dòng)偽影。幻影車(chē)身懸掛在非磁軌上，可以進(jìn)行線圈定位和虛擬注冊(cè)到沙發(fā)上。





CIRS008MMRI動(dòng)態(tài)模體，CIRS008M模體含有MRI質(zhì)量保證目標(biāo)，與ACR認(rèn)證計(jì)劃的建議相符：

MRI圖像空間失真
MRI場(chǎng)均勻性
激光到ISO中心重合
帶有模擬目標(biāo)的活動(dòng)插件是一個(gè)密封的圓柱形桿，其填充了與幻像體相同的MRI信號(hào)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(duì)的對(duì)比度。該目標(biāo)可以接收離子室或其他MRI兼容劑量計(jì)用于治療劑量驗(yàn)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(duì)準(zhǔn)的中心基準(zhǔn)點(diǎn)，并且在關(guān)于3D空間畸變網(wǎng)格的已知位置。

CIRS008MMRI動(dòng)態(tài)模體，CIRS008M模體特征：
MRI-CT-LINAC兼容
3D目標(biāo)運(yùn)動(dòng)
門(mén)控和自適應(yīng)RT計(jì)劃驗(yàn)證
