The angiograms are frequently used to find anomalies in the blood vessels. Hence, for improving the quality of the images with an angiogram, a Morse filter will be implemented (based on the model of the Morse Potential) in a brain’s vessels angiogram using both softwares Maple ® and ImageJ ®. It will be shown the results of applying a Morse filter to an angiogram of the brain vessels. First, the image was processed with ImageJ using the plug-in Anisotropic Diffusion 2D and then, the filter was implemented. As it is illustrated in the results, the edges of the stringy elements are emphasized. Particularly, this is very useful in the medical image processing of blood vessels, like angiograms, due to the narrowing or obstruction which may be caused by illness like aneurysms, thrombosis or other diseases.
