    • A method and system for the use of a CAD algorithm that can be used to automatically detect retained colonic fluid and the rectal tube in computed tomographic (CT) imagery of a patient's colon is disclosed. The CAD algorithm can then electronically subtract the fluid and rectal tube from the images and the modified CT imagery can then be displayed to a user, such as a radiologist. Both the original and modified CT imagery will be stored for future presentation and review. The user, including the radiologist or other medical personnel, will have the option to toggle between displaying and reviewing the modified and original imagery. After subtraction, the radiologist will be able to view the imagery containing all pertinent information regarding the colonic lumen and any suspect region within the colon. Additionally, full processing of the scan is possible even when fluid retention in the colon is greater than fifty percent in any region.
    • 公开了一种用于使用CAD算法的方法和系统,该算法可用于自动检测患者结肠的计算机断层摄影(CT)图像中的保留结肠液和直肠管。 然后,CAD算法可以从图像中电子地减去流体和直肠管,然后可以将修改的CT图像显示给诸如放射科医师的用户。 原始和修改的CT图像将被存储以供将来的介绍和审查。 用户,包括放射科医师或其他医务人员,可以选择显示和查看修改和原始图像。 减法后,放射科医生将能够查看含有关于结肠腔和结肠内任何可疑区域的所有相关信息的图像。 此外,即使在任何地区的结肠中的流体保留量都大于百分之五十,扫描的全部处理也是可能的。
