英國(guó)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(guó)Leeds TOR ABC光束校準(zhǔn)模體,TOR ABC光束校準(zhǔn)模體對(duì)象設(shè)計(jì)用于定期(例如每周/每月)快速簡(jiǎn)便地提供光束對(duì)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(chǎng)與有效輻射場(chǎng)的對(duì)應(yīng)關(guān)系。
確定中心束的位置。
相對(duì)于膠片/檢測(cè)器平面的90°的中心光束角度偏差低于極限值,超過這個(gè)極限值會(huì)對(duì)圖像質(zhì)量產(chǎn)生不利影響。
TOR ABC模體可以單獨(dú)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.
