An abdominal aortic aneurysm doesn't result in specific symptoms, and so providing a successful diagnosis can be challenging. Patients may require surgery for successful treatment, with the risk of aortic rupture being dependent on diameter. In this study, a CT screen of a patient with an aneurysm of the abdominal aorta was processed. In order to provide a more accurate and comfortable diagnosis, and to more easily determine the diameter of the abdominal aortic aneurysm, the Sobel and Top-hat methods were employed. Using a filtered screen overlap for the CT scan, the aortic diameter of a patient could be compared with the diameter of a healthy individual, thus allowing an immediate and accurate comparison. It was found that with a diameter of more than 40 mm the risk of rupture is higher.
