摘要:
Beam enhancement through sidelobe reduction and/or mainlobe sharpening is shown. Embodiments utilize dynamic resolution, improved dynamic resolution, and/or enhanced dynamic resolution techniques to synthesize beams, such as ultrasonic beams used in ultrasonic imaging, having desired attributes. Embodiments simultaneously form a first sample beam and a second or auxiliary sample beam for every sample to synthesize enhanced scan beams. According to a dynamic resolution techniques herein a new beam may be formed from the sum of the two sample beams. A synthesized dynamic resolution beam of embodiments has reduced sidelobes with relatively little or no spread of the mainlobe. An enhanced dynamic resolution beam sharpening function can be applied to provide a further enhanced beam, such as to further narrow the mainlobe.
