FIELD: physics.
SUBSTANCE: ultrasonic diagnostic imaging system produces an extended field of view (EFOV) image. A three-dimensional imaging probe is moved along the skin of a patient above the body part which is to be included in the EFOV image. As the probe is moved, images are acquired from two differently oriented planes such as a sagittal plane and a transverse plane. As the probe is moved the image data of successive planes of one of the orientations is compared to estimate the motion of the probe. These motion estimates are used to position a series of images acquired in one of the orientations accurately with respect to each other in an EFOV display format. The display format may be either a two-dimensional EFOV image or a three-dimensional EFOV image.
EFFECT: high accuracy when reconstructing EFOV images.
