CIRS 731-HN头部剂量模体，CIRS 731-HN头部模体
CIRS 731-HN头部剂量模体是一种拟人头模型，用于任何适形或IMRT质子治疗系统的调试和治疗计划系统（TPS）验证。
CIRS 731-HN头部剂量模体由CIRS组织等效材料构成，其模拟质子在1.5％以内的参考组织和在50KeV到15MeV的光子在1％以内。质子治疗头可用于从CT图像采集到质子束输送验证的所有标准IMRT程序。
CIRS 731-HN头部剂量模体特点和好处
理想的治疗计划评估在高密度梯度的地点，如气腔与骨骼结构。
内部结构包括大脑，骨与皮质和小梁的区别，喉，气管，完全开放的窦腔，鼻腔和口腔，以及具有独特的牙本质，牙釉质和牙根结构的牙齿。
在尺寸和结构上近似于男性平均头部，以允许与任何患者定位或固定装置直观地设置。
一半的人体模型以2cm的增量分成三个位于颅 - 尾方向的影像位置，从矢状面的近似中心开始。
由于切片与CT轴平面正交，因此与标准轴向切片相比，由残留气隙引起的伪影明显减少。
质子系统调试通过在臼齿中放置钨BB和通过在C3和C5椎骨上的两个螺钉连接的钛假体来增强。

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.
