摘要：Cardiac catheterization is the process of inserting a tube called a catheter into the heart through an artery such as the femoral artery or aortic artery to reach the left ventricle of the heart or coronary arteries for diagnostic purposes such as ventricular injection left or coronary arteries that can facilitate X-ray vision or the introduction of therapeutic equipment. Image enhancement will be represented as one of the main areas of interest of most of researchers. For human interpretation the subjective quality of images is so important. Thus different image enhancement techniques have been used to provide a better diagnosis. The aim of this paper is how to enhance the visualization of the cardiac image to be more suitable to the doctor in order to make a correct decision for the patient. This implemented system can be divided into many steps including preprocessing, enhancement and decision making. The focus of this research is on how to improve the features of the image so as to be clear to the doctor. Two types of filters (Gaussian and Average) were applied and then the results were compared for both types. The Gaussian filter showed better results in improving the image parameters.
