Description
Summary:碩士 === 臺北醫學大學 === 醫學資訊研究所 === 98 === CT scanners are widely used in non-invasive examination. In order to ensure that the CT scan image quality, will need to rely on special equipment produced by the detection image, and then through the image measurements and visual way to judge. There are several key parameters of image quality is good or bad at stake; including Contrast scale, High Contrast Resolution, Low contrast detectability, Noise and Uniformity, Laser Accuracy. This study would like to computed tomography image quality through program analysis, analyzing Contrast scale, High Contrast Resolution, Low contrast detectability, Noise and Uniformity, Laser Accuracy. And directly displayed on the screen, so that staff do not have to take the time to be able to understand the current status of image quality.
