摘要： Portions of a virtual colon can be analyzed to identify a normal structure, such as an ileocecal valve. Paradigmatic characteristics of ileocecal valves can be used to identify a digital representation as an ileocecal valve. Upon determination that a digital representation has the characteristics of an ileocecal valve, action can be taken. For example, the digital representation can be removed from a list of polyp candidates.

摘要： A method for generating colonography images for colorectal screening of a patient. The patient is administered an amount of radiopaque stool marker which will enable stool present in the patient's colon to be distinguished from soft tissue. The patient's colon is imaged after the stool marker has been administered to generate colonography images. Preparation of the colon is simulated by processing the colonography images to remove marked stool before the images are observed during a diagnosis session.
