Ready-Pac膠片可以插入CIRS 009魔方模體中。通過旋轉(zhuǎn)立方體，電影很容易設(shè)置在矢狀，冠狀或橫向。不銹鋼基準(zhǔn)點(diǎn)在CT圖像上清晰可辨，并在薄膜上留下小的凹痕，以便精確的薄膜計(jì)劃對位。根據(jù)要求，在接口表面可以銑削一個(gè)凹槽，用于5 x 6“的射線照相膠片的暗室加載。
he CIRS Model 009 Cube 20 Phantom was designed for routine QA in RT and IMRT applications where ease of use and quick set-up are important. The Cube 20 phantom is manufactured from Plastic Water? DT which faithfully mimics the linear attenuations of water within 1% from 50 keV to 15 MeV. This enables complete QA from CT image acquisitions to therapy dose verifications. The 20 cm cubic dimension was chosen as a suitable approximation for both head/neck and torso treatments. All the edges are rounded to avoid CT artifacts.
Chamber, diode or MOSFET detectors are easily bed at isocenter of the cube and laser alignment marks on all sides facilitate precise bing of the phantom.* Detector b can be adjusted in 1 mm increments longitudinally and 5 mm increments for lateral and elevational adjustments.
Ready-Pac film can be inserted in the Cube. By rotating the cube, the film is easily set in sagital, coronal or transverse orientations.
Stainless steel fiducials are bly resolvable on CT images and leave small indentations on the film for precise film to plan registration. Upon request, a recess can be milled in the interface surface for darkroom loading of radiographic film 5 x 6".
