To investigate whether there is any difference in the presented image quality between a medical grade monitor and a "commercial off-the- shelf" (COTS) monitor when displaying an 8-bit dental image.
The digital imaging and communications in medicine (DICOM) part 14: greyscale standard display function (GSDF) was verified for both monitors. A visual grading characteristics (VGC) curve was constructed to measure the difference in image quality between the two monitors by comparing radiological structures displayed on each monitor with a DICOM part 14: GSDF-calibrated laptop monitor as reference.
All of the monitors conformed to within the American Association of Physicists in Medicine Task Group 18 10% tolerance levels for the assessment of the DICOM part 14: GSDF. There was no difference in the preferred perceived visual sensation for the displayed image between the two tested monitors with the area under the VGC curve = 0.53 and 95% confidence interval = 0.47-0.59.
A DICOM part 14: GSDF COTS monitor is capable of displaying an image quality that is equally preferred to a DICOM part 14: GSDF medical grade monitor for an 8-bit image file.
研究在显示8位牙科图像时,医用级显示器和“商用现货”(COTS)显示器所呈现的图像质量是否存在差异。
对两台显示器的医学数字成像和通信(DICOM)第14部分:灰度标准显示功能(GSDF)进行验证。通过将每台显示器上显示的放射结构与经DICOM第14部分:GSDF校准的笔记本电脑显示器进行比较,构建视觉分级特性(VGC)曲线,以测量两台显示器之间的图像质量差异。
所有显示器在评估DICOM第14部分:GSDF时均符合美国医学物理学家协会任务组18的10%公差水平。两台受试显示器上显示图像的首选感知视觉感受没有差异,VGC曲线下面积=0.53,95%置信区间=0.47-0.59。
对于8位图像文件,DICOM第14部分:GSDF的COTS显示器能够显示出与DICOM第14部分:GSDF医用级显示器同样优质的图像。
