Computer Aided Detection Improving for Virtual Colonoscopy

One of the most important preventive imaging tests that is regularly done is the screening for colon cancer. And one of the most useful innovations was the development of the virtual colonoscopy which made this screening more efficient and easier on the patient, thereby increasing the likelihood that patients will get this testing done. The next step is to make the virtual colonoscopy even more effective, a step which requires developing and improving the computer-aided detection (CAD) software which is used CAD software is used to assist the doctor in confirming his diagnosis. The computer scans and assess digital images in order to highlight and emphasize certain areas in the scan. The doctor can use this information to double-check his or her initial assessment of the testing. CAD software is a relatively new technology which is still being improved. A new study shows that CAD software can indeed be very helpful to the doctor who is studying virtual colonoscopy scans. The study revealed that the CAD technology was capable of studying both cleansed and uncleansed, tagged and untagged images in order to determine if there were cancerous polyps in the image. The software isn't perfect; there were more false positives than doctors would like to see. However it's a good step in the right direction for using computer imaging to support a doctor's analysis. Question of the Day: In what other imaging procedures do you believe CAD software is most useful? photo link
