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.

摘要： Systems and methods which provide active optimized spatio-temporal sampling (AOSTS) for image generation are shown. Embodiments actively select one or more regions of interest (ROIs) in a multi-beam ultrasound sampling mode, to minimize temporal image artifacts in the ROIs and thereby provide AOSTS. Such selection of ROIs according to embodiments results in various multi-beam sampling parameters, such as the number of rays that are used, the spacing between the rays that are used, the width of the rays that are used, the sequence of the rays that are used, the angle of the rays that are used, etc., being selected to provide optimized spatio-temporal sampling with respect to the selected ROIs. Selection of ROIs according to embodiments may include selecting parameters such as position, size, shape, orientation, direction, rate of change, etc.
