CIRS 731-HN頭部劑量模體，CIRS 731-HN頭部模體

    
CIRS 731-HN頭部劑量模體是一種擬人頭模型，用于任何適形或IMRT質(zhì)子治療系統(tǒng)的調(diào)試和治療計(jì)劃系統(tǒng)（TPS）驗(yàn)證。

CIRS 731-HN頭部劑量模體由CIRS組織等效材料構(gòu)成，其模擬質(zhì)子在1.5％以內(nèi)的參考組織和在50KeV到15MeV的光子在1％以內(nèi)。質(zhì)子治療頭可用于從CT圖像采集到質(zhì)子束輸送驗(yàn)證的所有標(biāo)準(zhǔn)IMRT程序。

CIRS 731-HN頭部劑量模體特點(diǎn)和好處
理想的治療計(jì)劃評(píng)估在高密度梯度的地點(diǎn)，如氣腔與骨骼結(jié)構(gòu)。
內(nèi)部結(jié)構(gòu)包括大腦，骨與皮質(zhì)和小梁的區(qū)別，喉，氣管，完全開放的竇腔，鼻腔和口腔，以及具有獨(dú)特的牙本質(zhì)，牙釉質(zhì)和牙根結(jié)構(gòu)的牙齒。
在尺寸和結(jié)構(gòu)上近似于男性平均頭部，以允許與任何患者定位或固定裝置直觀地設(shè)置。
一半的人體模型以2cm的增量分成三個(gè)位于顱 - 尾方向的影像位置，從矢狀面的近似中心開始。
由于切片與CT軸平面正交，因此與標(biāo)準(zhǔn)軸向切片相比，由殘留氣隙引起的偽影明顯減少。
質(zhì)子系統(tǒng)調(diào)試通過在臼齒中放置鎢BB和通過在C3和C5椎骨上的兩個(gè)螺釘連接的鈦假體來增強(qiáng)。

The CIRS Proton Therapy Dosimetry Head is an anthropomorphic head phantom designed for commissioning and treatment planning system (TPS) verification with any conformal or IMRT Proton Therapy system.

The phantom is constructed of CIRS tissue-equivalent materials, which mimic reference tissues within 1.5% for protons and within 1% for photons from 50 KeV to 15 MeV. The Proton Therapy Head can be used during all standard IMRT procedures from CT image acquisition to proton beam delivery verification.

Features and Benefits
Ideal for treatment plan evaluation in high density-gradient locations such as air cavity vs. bone structures.
Internal structures include brain, bone with cortical and trabecular distinction, larynx, trachea, fully-open sinus cavities, nasal and mouth cavities, and teeth with distinct dentine, enamel and root structure.
Approximates the average male human head in both size and structure to allow for intuitive set up with any patient positioning or fixation device.
One half of the phantom is sectioned in 2cm increments for three film locations in the cranio-caudal direction starting from the approximate center of the sagittal plane.
Because slices are orthogonal to the CT axial plane, artifacts caused by residual air gaps are noticeably reduced compared to standard axial slices.
Proton system commissioning is enhanced by placement of a tungsten BB in a molar and a titanium prosthesis attached by two screws at C3 and C5 vertebra.
