Abstract: Shadow suppression is provided in ultrasound imaging, such as in steered spatial compounding. Using a transform or other approach, the data of a frame of data along the steering direction is projected. The projection is used to determine weights. The frame is weighted with the projection-based weights, reducing or removing shadows based on the one frame rather than based on registration with other frames. In the steered spatial compounding example, a compounded frame with independently shadow suppressed component frames may have little or no fork-like image artifacts due to shadowing.

Abstract: B-mode ultrasound imaging is optimized for a user's region of interest. For B-mode imaging, a region of interest is determined. Some indication of a location or locations of interest to the user in the B-mode image is used to identify the region of interest. The parameters used for B-mode imaging are then set based on the identified region of interest rather than an entire B-mode field of view. Subsequent B-mode imaging is performed with these parameters optimized for the region.

Abstract: Shear wave imaging is provided in medical diagnostic ultrasound. The generation of a shear wave with acoustic energy forms a pseudo shear wave (an apparent wave) traveling towards the transducer. Transmission and reception along a single line may be used to detect the pseudo shear wave traveling towards the transducer. The shear velocity or characteristic may be determined without reception along multiple laterally spaced scan lines. One transmission to generate the shear wave may be used. With multi-beam receive or without, calculating shear velocity from along a single line allows rapid determination.
