ABSTRACT:
A method and system for registration of multiple ultrasound images or frames of data are provided. The images are registered as a function of relative movement of the transducer. A feature or feature pattern, such as one or more structural edges, are identified in one image. The feature or feature pattern is represented by fewer than all of the data points within a frame of data. Based on the identification of a particular feature or feature pattern, relative motion is estimated by correlating the feature pattern with another image in various relative positions. The best correlation is selected. The motion is estimated by selecting a translation and rotation of the position associated with the best correlation. The frames of data are registered and compounded to generate the panoramic field of view image as a function of the estimated motion. The panoramic field of view image comprises a B-mode image, or a color Doppler image, or an image that is a combination of both. The imaging may be static or dynamic.
