Abstract: An ultrasound system produces maps of acoustic attenuation coefficients from pulse echo signals. Maps are produced using different attenuation coefficient or slope estimation methods, and a plurality of maps from different estimation methods are compounded to produce a final attenuation coefficient map. Confidence maps may also be produced for one or more attenuation coefficient maps, and the confidence map displayed or its measures used to determine weighting for the compounding process.

Abstract: A method for using an interactive visual guidance tool for an imaging acquisition and display configured for user navigation with respect to a blockage of a field of view detects, and spatially defines, the blockage. It also integrates, with the image for joint visualization, an indicium that visually represents the definition. The indicium is moved dynamically according to movement, relative to the blockage, of the field of view. The indicium can be shaped like a line segment, or two indicia can be joined in a “V” shape to frame a region of non-blockage. The defining may be based on determining whether ultrasound beams in respective directions are blocked.

Abstract: Systems and methods for calculating hepato-renal index (HRI) values from radiofrequency (RF) data are disclosed herein. The RF data may include fundamental frequency components, harmonic frequency components, or a combination thereof. Signal intensities within regions of interest may be calculated from the RF data. The signal intensities may be averaged to arrive at an average signal intensity value for each region of interest. In some examples, some of the highest and/or lowest signal intensity values may be removed prior to averaging. The ratio of the average signal intensities from the different regions of interest may be then be taken to arrive at the HRI values.

Abstract: The invention provides a method for generating a filtered ultrasound image. The method begins by obtaining channel data. First and second apodization functions are applied to the channel data to generate first (610) and second (620) image data, respectively. A minimization function is then applied to the first (610) and second (620) image data, which may then be used to generate third (630) image data. The filtered ultrasound image may then be generated based on the first (610) and third (630) image data.

Abstract: Systems and methods for reducing speckle while maintaining frame rate are disclosed. Multiple sub-images associated with different receive angles are acquired for a single transmit/receive event at an observation angle. The sub-images are compounded to generate a final image with reduced speckle. In some examples, multiple sub-images from multiple transmit/receive events are compounded to generate the final image. The observation angle and/or the receive angles may vary between transmit/receive events in some examples.

Abstract: The invention provides an ultrasound data processing method for pre-processing signal data in advance of generating ultrasound images. The method seeks to reduce noise through application of coherent persistence to a series of raw ultrasound signal representations representative of the same path or section through a body but at different successive times. A motion compensation procedure including amplitude peak registration and phase alignment is applied to raw echo signal data in advance of application of persistence in order to cohere the signals and thereby limit the introduction of motion induced artifacts.

Abstract: Systems and methods for ultrasound shear wave elastography (SWE) are described. According to examples, an ultrasound SWE system includes an ultrasound probe (120), an actuation assembly (130) coupled to the probe and configured to apply an external force against a subject for generating a shear wave within a target region, a controller (140) coupled to the actuation assembly to control the actuation assembly to apply the force responsive to a trigger signal, and ultrasound scanner (110) configured to generate the trigger signal, and further configured to generate an elastography image based at least in part on echo signals received from the target region.

Abstract: A system for performing ablation includes an ablation device (102) configured to ablate tissue in accordance with control parameters and configured to make measurements during the ablation process. An imaging system (104) is configured to measure an elastographic related parameter to monitor ablation progress. A parameter estimation and monitoring module (115) is configured to receive the measurements from the ablation device and/or the elastographic related parameter to provide feedback to adaptively adjust imaging parameters of the imaging device at different times during an ablation process.

Abstract: An apparatus includes an imaging probe and is configured for dynamically arranging presentation of visual feedback for guiding manual adjustment, via the probe, of a location, and orientation, associated with the probe. The arranging is selectively based on comparisons between fields of view of the probe and respective results of segmenting image data acquired via the probe. In an embodiment, the apparatus includes a sensor which guides a decision that acoustic coupling quality is insufficient, the apparatus issuing a user alert upon the decision.
