  • Patent number: 12245890
    Abstract: User feedback on acquisition of ultrasound data may be provided to a user. The feedback may indicate a quality of the acquisition and/or the reliability of the measurements calculated from the ultrasound data, for example, the volume flow measurements calculated from Doppler data. Various quality factors such as a signal-to-noise ratio (SNR), motion, Doppler angle, vessel size, vessel depth, and/or variance in velocity values may be determined to provide an indication of quality of the acquisition. The quality factors may be provided individually or in combination. In some examples, one or more quantitative values of the quality factors may be provided. In some examples, one or more qualitative indications of the quality of the acquisition may be provided.

  • Patent number: 12193871
    Abstract: Various embodiments of the present disclosure include a thermal ablation probabilistic controller (30) employing an ablation probability model (32) trained to render a pixel ablation probability for each pixel of an ablation scan image illustrative of a static anatomical ablation. In operation, the thermal ablation probabilistic controller (30) spatially aligns a temporal sequence of ablation scan datasets representative of a dynamic anatomical ablation, and applies the ablation probability model (32) to the spatial alignment of the temporal sequence of ablation scan datasets to render the pixel ablation probability for each pixel of the ablation scan image illustrative of the static anatomical ablation.

  • Patent number: 12193880
    Abstract: The present disclosure describes ultrasound systems configured to perform microbubble-based contrast imaging with enhanced sensitivity. The systems can enhance echo signals derived from microbubbles while suppressing echo signals derived from tissue by detecting phase shifts exhibited by microbubbles in resonance. To detect the phase shifts, and thereby distinguish between microbubble-based signals and tissue-based signals, the systems can transmit a series of ultrasound pulses into a target region in accordance with a predefined sequence. The sequence can include an initiation pulse configured to stimulate microbubbles into nonlinear oscillation, a detection pulse configured to detect the nonlinear oscillation, and a summation pulse formed by transmitting an initiation pulse and detection pulse with a small time delay therebetween.

  • Patent number: 12178654
    Abstract: An ultrasound system produces maps of acoustic attenuation coefficients from B mode image signals. A plurality of maps located in different parallel and elevationally separated planes (A, B, C, D, E) are produced, then compounded in the elevation direction. 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. The compounding of elevationally separate planes improves attenuation coefficient estimation in the presence of blood vessels affecting the estimates in one or more of the planes.

  • Publication number: 20240423588
    Abstract: A system for medical imaging is disclosed. The system includes an ultrasound (US) probe connected by a US cable having a sensor along its length. The sensor is adapted to gather measurement data from the US cable. The system also has a processor and a memory. The memory stores instructions, which when executed by the processor, cause the processor to: input the measurement data to a trained computational model; and apply the trained computational model to the measurement data to predict cable integrity of the US cable based on ground truth data, or to forecast a remaining useful life (RUL) of the US cable using ground truth data, or both. A sensor including a flexible textile-like substrate is also described. The sensor is embedded in the substrate and along a length of the US cable.

  • Publication number: 20240315674
    Abstract: An ultrasonic diagnostic imaging system and method produce attenuation coefficient maps of a region of interest in an ultrasound image. In order to detect the presence of elevation aperture blockage, the system estimates attenuation coefficients by two different methods. The estimates produced by the two different methods are combined to produce a metric, which is evaluated as a function of depth. If the metric satisfies one or more criteria of measurement bias, elevation aperture blockage is identified and an alert of the blockage is produced for the user.

  • Publication number: 20240180519
    Abstract: Guidance may be provided to users, at least in part, by graphic overlays on displays of ultrasound images. The guidance may assist users in acquiring images suitable for making hepato-renal index (HRI) measurements. In some examples, the guidance may assist the user in finding the proper imaging plane including a portion of the liver and kidney. In some examples, the guidance may further assist the user in proper placement of regions of interest within the image for calculating the HRI, such as at the same depth and appropriate portions of the liver and kidney. In some examples, one or more processors may analyze the image to ensure the quality is suitable for calculating the HRI.

  • Publication number: 20240119705
    Abstract: An ultrasound imaging system may acquire an image of a liver. The liver may be segmented from the image. Parameters, such as image homogeneity map, intensity probability chart, and/or speckle size diagram, may be extracted from the liver portion of the image. The parameters may be used to determine whether fatty liver deposits are diffuse or inhomogeneous. In some examples, inhomogeneous regions may be excluded from the calculation of liver fat quantification measurements. In some examples, the inhomogeneous regions may be displayed so that a user may select a region of interest that excludes the inhomogeneous regions to calculate the liver fat quantification measurements.

  • Publication number: 20240099699
    Abstract: Apparatuses, systems, and methods are provided for automatically selecting first and last frames for a sequence of frames from which an accumulation contrast image may be generated. In some examples, statistical distributions of groups of pixels of the image frames may be analyzed to generate parametric maps. The parametric maps may be analyzed to select the first and last image frames of the sequence. In some examples, an image frame corresponding to the parametric map having a value above a threshold value may be selected as a first frame. In some examples, an image frame corresponding to the parametric map having a maximum value of all the parametric maps may be selected as the last frame. In some examples, the parametric maps may be used to segment features, such as a tumor, from the image frame.

  • Patent number: 11766244
    Abstract: The present disclosure describes ultrasound systems and methods configured to determine the elasticity of a target tissue. Systems can include an ultrasound transducer configured to acquire echoes responsive to ultrasound pulses transmitted toward the tissue, which may include a region of increased stiffness. Systems can also include a beamformer configured to control the transducer to transmit a push pulse into the tissue, thereby generating a shear wave in the region of increased stiffness. The beamformer can be configured to control the transducer to emit tracking pulses adjacent to the push pulse. Systems can further include a processor configured to determine a displacement amplitude of the shear wave and based on the amplitude, generate a qualitative tissue elasticity map of the tissue. The processor can combine the qualitative map with a quantitative map of the same tissue, and based on the combination, determine a boundary of the region of increased stiffness.

  • Patent number: 11647991
    Abstract: In an ultrasound imaging system which produces synthetically transmit focused images, the multiline signals used to form image scanlines are analyzed for speed of sound variation, and a map 60 of this variation is generated. In a preferred implementation, the phase discrepancy of the received multilines caused by speed of sound variation in the medium is estimated in the angular spectrum domain for the receive angular spectrum. Once the phase is estimated for all locations in an image, the differential phase between two points at the same lateral location, but different depth, is computed. This differential phase is proportional to the local speed of sound between the two points. A color-coded two- or three-dimensional map 60 is produced from these speed of sound estimates and presented to the user.
