Abstract

Quality of ultrasound image is dominantly limited by two major issues such as low resolution and speckle noise. The existing speckle reduction techniques are mostly applied either before or after scan conversion. Filtering before scan conversion results in huge computational load since the amount of data handled is quite large while filtering after scan conversion provides poor image quality. In this paper, a novel and computationally efficient filtering technique has been proposed where filtering is performed along with scan conversion using spatial linear adaptive and nonlinear filters in two directions of scan conversion geometry. The proposed framework is found suitable for the real-time applications and improves the visual quality of the image. Quality metrics for the proposed method have been compared to other existing methods to show the novelty of the work.
