This paper presents a method of measurement of blood vessel characteristics for disease detection based on cone-beam CT images.
The important objective here is to show how representation of blood vessel morphology can lead to feature measurement and identification of abnormal regions.
We represent the blood vessel surface through curvatures and then measure the surface characteristics that emphasize disease such as aneurysm and stenosis.
From results of an application to a patient's abdominal blood vessels containing two aneurysms and one stenosis, we show the feasibility of our method to direct the physician's attention to the location of the abnormality.
