英國Leeds TOR ABC光束校準(zhǔn)模體，TOR ABC光束校準(zhǔn)模體產(chǎn)品描述
英國Leeds TOR ABC光束校準(zhǔn)模體，TOR ABC光束校準(zhǔn)模體對象設(shè)計用于定期（例如每周/每月）快速簡便地提供光束對準(zhǔn)和居中檢查。

用于X線攝影或透視檢查，可以進(jìn)行以下檢查：

光場與有效輻射場的對應(yīng)關(guān)系。
確定中心束的位置。
相對于膠片/檢測器平面的90°的中心光束角度偏差低于極限值，超過這個極限值會對圖像質(zhì)量產(chǎn)生不利影響。
TOR ABC模體可以單獨使用，也可以使用  吊架垂直bucky夾具  或  吸氣垂直bucky夾具。









TOR ABC
Radiography & Fluoroscopy Phantom

A routine test object designed to be used quickly and easily on a regular basis (e.g. weekly/monthly) to provide an ongoing check of beam alignment and centring.
Used for radiography or fluoroscopy, enables the following
checks to be made:
 The correspondence of the light field with the effective
radiation field.
• The determination of the position of the central beam.
• The central beam angle deviation from 90°, relative to the plane of the film/detector, is below a limit that beyond which the image quality would be adversely affected.
