The value of 18F-FDG dual head SPECT coincidence imaging in diagnosis of lung cancer 18F-FDG双探头符合线路SPECT在肺癌诊断中的价值
Objective To evaluate the value of18F-FDG Dual Head(DH) Coincidence ( DHC ) in the diagnosis of solitary pulmonary nodules ( SPN ). 目的探讨18F-氟脱氧葡萄糖双探头符合线路显像对肺部孤立性结节的诊断价值。
Objective To investigate the influence of attenuation correction ( AC ) on dual head coincidence imaging resolution and counts. 目的研究衰减校正对双探头符合成像系统分辨率及图像计数的影响。
Methods The images of chest phantom were acquired with Dual Head(DH) Coincidence mode. 方法用胸部模型作双探头符合显像。
One of the effective methods to enlarge the display desktop is the so called " multihead ", which is different with the traditional Dual Head(DH) technique that copies the same content to all display devices. 扩大显示桌面的有效方法之一是多屏显示,它不同于以往的双头(DH)显示技术,后者在每个显示设备上都显示相同的内容。
