X射線測(cè)試模式用于高對(duì)比度和/或空間分辨率測(cè)量。

SKUTPye-XX類別放射診斷
產(chǎn)品介紹
X射線測(cè)試卡用于高對(duì)比度和/或空間分辨率測(cè)量:

  • 該程序在X射線質(zhì)量保證和服務(wù)中有著悠久的傳統(tǒng),并且易于執(zhí)行。
  • 測(cè)試模式用于評(píng)估膠片屏幕系統(tǒng)、放大技術(shù)和X射線成像系統(tǒng)的分辨率能力。
  • 這些圖案由各種鉛的厚度組成。各自的厚度通常在每個(gè)圖案上都有規(guī)定。每個(gè)測(cè)試模式通常被包裹在塑料中,即組織等同材料中。
  • 每個(gè)圖案的分辨率范圍因測(cè)試類型而異。
