Abstract
1 method is provided for obtaining an extended field of view diagnostic ultrasound image. A first image frame and a second image frame of an object of interest are acquired. The image frames are rotated relative to one another. Pixel points, representing spatial points in the object of interest, are identified in the first image frame. Pixel points corresponding to the pixel points in the first image frame are then computed in the second image frame. A rotation angle between the first and the second image frames is calculated based on a least-squares relation between the pixel points. The first and second image frames are combined to form a part of an extended field of view image.
