A novel imaging processing method using gray level co-occurrence matrix (GLCM) to evaluate microbubble concentration in ultrasonic particle image velocimetry (echo PIV) technique is presented in this paper. The image processing method is used to study the optimum microbubble concentration in Echo PIV imaging of a two dimensional blood flow field. It is found that for the GLCM correlation values for...
One important problem in ultrasound image processing is to find the edges of structures and enhance weak borders between different organs and structures. An approach was developed that detects and enhances edges adaptively based on image block correlation technique. From the image block correlation we can get the "local correlation image" LCI. On the basis of this image we apply an adaptive...
In recent years, volumetric (3D) cardiac ultrasound imaging has become more readily available in daily clinical practice due to the introduction of matrix array transducer technology. To date, quantitative analysis of these data sets typically requires a significant amount of user interaction. Recently, our teams introduced methods that could help in automating this process. On the one hand, an edge...
