The Application of the Region Growing Method to the Determination of Arterial Changes

The paper discusses segmentation of medical images depicting aortic aneurysms and atherosclerotic changes in coronary vessels. The region growing method was deployed for segmentation. Before segmentation with the aforementioned method, the images were subjected to edging in order to acquire significant information, such as the size of the analyzed structure and pixel distribution. Edging paired with the region growing method ensures proper isolation of pixels with the same intensity, without the unwanted pixel overflow. In order to verify the method, results obtained by various authors were referred to, and a statistical analysis was performed to calculate the Dice coefficient.
