PROBLEM TO BE SOLVED: To reduce banding at real time over a wide variety of body types of patients. SOLUTION: The banding is produced when two or more focal areas having, for example, diverging waveforms and/or frequencies are combined in a diagnostic image. Strength difference produced as a result between focal areas produces the banding in the last image. An implementation demonstrates a method (400) about two focal zones. The banding in the diagnostic image including two or more focal zones is reduced by treating the first focal zone, determining intensity around a boundary between two or more focal areas or stitch lines, and modulating the second focal area based on strength difference. Preferably, the treatment is performed at real time simultaneously with updating of an image frame. COPYRIGHT: (C)2004,JPO |
