A method for improving the resolution of ultrasound images using synthetic aperture concepts. A two-dimensional image is obtained using ultrasound imaging apparatus located at a first position outside the target area and at a predetermined distance from a center point within the target area. The imaging apparatus is then moved along an arc to a new position and another two-dimensional ultrasound image is obtained. This process is repeated through up to a full around the target area. Image data for each pixel is combined, calculated and transformed for all image positions to produce a highly resolved image of that pixel. The process is repeated for each pixel until all the pixels within the target area are fully resolved, thereby producing a complete, highly resolved over-all image.
