Abstract

Unenhanced computed tomography (CT) brain images are normally displayed by adjusting the window setting, which shows the images from the Digital Imaging and Communications in Medicine format into the standard grayscale format. The two parameters in the window setting are the center level and the window width, which are adjusted to show the region of interest. Various parameters or related indicators that affect the window setting are studied. Four mathematical central moments, namely, mean, variance, kurtosis, and skewness, are applied and compared on different CT brain images. Results show that the third and fourth moments are inversely proportional to the window width. Comparisons are made on the effects of these settings using different existing techniques including the expert evaluations from the hospital staff
