CIRS 002HN IMRT模體原產地：美國
CIRS 002HN IMRT模體旨在解決有關治療計劃系統的調試和比較以及驗證個別患者計劃和交付的復雜問題。
CIRS 002HN IMRT模體在形狀，比例和結構以及密度上都能恰當地代表人類頭頸部的解剖結構。這可以對治療計劃和分娩系統進行徹底的分析。模體是由獨特的專有材料制造的，忠實地模仿從50 keV到25 MeV的1％以內的骨骼和水。
CIRS 002HN IMRT模體的形狀是圓形的，接近一般病人的大小。用于電離室的組織等效互換桿插入件允許在幻影和膜校準中的多個平面上進行點劑量測量。模體還支持膠片劑量學不僅標準射線膠片，而且還支持Gaf-Chromic?媒體。可選插件可用于支持各種其他探測器，包括TLD，MOSFET和二極管。
容納一個橫向的一個Ready Pack 10“×12”薄膜，兩個橫向放射性放射線或放射線10×10cm薄膜以及三個不同方向預切成63.5×63.5mm的十三個放射性變色薄膜的疊層。
模體表面刻有凹槽，以確保CT切片的正確定位和準確的薄膜計劃配準。

The CIRS Model 002HN IMRT phantom is designed to address the complex issues surrounding commissioning and comparison of treatment planning systems and verification of individual patient plans and delivery.
The CIRS 002HN phantom properly represents human head and neck anatomy in shape, proportion and structure as well as density. This enables thorough analysis of both the treatment planning and delivery systems. The phantom is constructed of proprietary tissue equivalent epoxy materials. Linear attenuations of the simulated tissues are within 1% of actual attenuation for bone and water from 50 keV to 15 MeV.
The phantom is circular in shape, approximates the size of an average patient. Tissue equivalent interchangeable rod inserts for ionization chambers allow for point dose measurements in multiple planes in the phantom and film calibration.* The phantom also supports film dosimetry with not only standard radiographic films but also GafChromic? media. Additional inserts are available to support a variety of other detectors including TLD’s, MOSFET, and diodes.
The Model 002HN accommodates one Ready PackTM 10” x 12” films in transverse orientation, two radiochromic or radiographic 10 x 10 cm films in transverse orientation and a stack of thirteen radiochromic films pre-cut to 63.5 x 63.5 mm in three different orientations.
The Model 002HN has an optional four Electron Density reference plugs which can be interchanged in five separate locations within the phantom. The surface of the phantom is etched with grooves to ensure proper orientation of the CT slices and accurate film to plan registration. An optional cranial bone ring is also available.
