Abstract: The present disclosure is directed to enhancing a lumen display in a CT sectional image of a blood vessel. The CT sectional image may be displayed with a first window level. An average CT value of lumen sections near the heart may be obtained, and a highest CT value of a section of a current blood vessel may also be obtained. A window level may be determined based on the average CT value and the highest CT value. At least a part of the section of the current blood vessel may then be displayed with the window level. The techniques allow for a window level to be preset to enhance lumen display and to improve the consistency of delineating the lumen contour, thereby avoiding deviations caused by subjective selection while saving time and improving patient flow.
