這是我們學校的作業

要英翻中

有點難翻....

我需要一個方向

所以我想請各位英文超強的大大們幫我一下吧~

拜託了~

就是以下這篇

TEST 9 Hard Copy Output

PHANTOM OR EQUIPMENT : A stepped gray-scale image generated by the computer or by some other means and a film densitometer. Scanning a stairstep wedge constructed of plastic can generate a gray scale. Each step of the wedge fills the width of X-ray beam with a larger fraction of plastic than the thinner step adjacent to it , and therefore it absorbs more X-rays. The greater absorption produces a slightly higher CT number at that step and a slightly lighter shade of gray in the image. After a satisfactory image has been generated , it should be saved and used as a standard against which future tests can be compared.

MEASUREMENT : Generate an image on film of the gray-scale image. Using a film den-sitometer , measure the density in the cen-ter of the stepped gray-scale image. One of the points of measurement is marked on the third step of the image.

EXPECTED RESULTS : The same image should be reproduced with the hard copy device each time the image is recorded. The levels of gray as measured by the den-sitometer should be unchanged between image.

POSSIBLE CAUSES OF FAILURE : Most fre-quently , drifts in the optical density of films from the camera can be traced to problems in the film processing. However , if the processor has been eliminated as a source of the problem , then the camera must be as-sumed to be the errant instrument. Some-times the video monitor , laser , or other light device used to expose the film has changed its output. In this case a service person should be called for repairs.

    測試 9硬拷貝輸出

    虛幻的或者設備:加強灰度圖像生成由計算機或其他手段和電影密度計。掃描一個梯形楔建造塑料可以產生一個灰色的規模。每一個步驟的楔形填充寬度的X射線束,帶有更大的分數比薄的塑料一步毗鄰,因此,它吸收更多的X射線。更大的吸收產生略高CT數在這一步並略有較淡灰色的形象。 經過一個滿意的形象已經產生,它應該被保存並作為一個標準,未來的測試進行比較。

    測試:生成一個圖像電影的灰度圖像。用電影登革sitometer,測量密度在岑之三的加強灰度圖像。其中一個測量點上標註的是第三步的形象。

    預期結果:在相同的圖像應再現與硬拷貝設備每次的形象記錄。灰色的水平作為衡量由登革sitometer形象之間應保持不變。

    可能的失敗的原因:大多數國語,吸收的敷料,漂移的光學密度的電影從鏡頭可以追溯到問題,影片處理。但是,如果處理器已被消滅作為源的問題,則必須作為相機,您屬意是武俠書。有些-時代的視頻監控,激光或其他光器件,用於揭露電影改變了它的輸出。在這種情況下,服務人員應要求維修。
