Abstract: The present disclosure describes ultrasound imaging systems and methods that may be used to image, for example, breast tissue. An ultrasound imaging system according to one embodiment may include a probe, a sensor attached to the probe and operatively associated with a position tracking system, a processor configured to receive probe position data from the position tracking system. The user interface may be configured to provide instructions for placement of the probe at a plurality of anatomical landmarks of a selected breast of the subject and receive user input to record the spatial location of the probe at each of the plurality of anatomical landmarks. The processor may be configured to determine a scan area based on the spatial location of the probe at each of the plurality of anatomical landmarks and generate a scan pattern for the selected breast. The processor may be further configured to monitor movement of the probe. The user interface may be configured to display, prior to scanning, a visual representation of the scan and automatically update, during scanning, the visual representation of the scan pattern based on movement of the probe.

Abstract: An ultrasound imaging system for needle insertion guidance uses a curved array transducer to scan an image field with unsteered beams as a needle is inserted into the image field. Due to differences in the angle of incidence between the radially directed beams and the needle, echoes will return most strongly from only a section of the needle. This section is identified in an image, and the angle of incidence producing the strongest returns is identified. Beams with this optimal angle of incidence are then steered in parallel from the curved array transducer to produce the best needle image. The steep steering angles of some of the steered beams can give rise to side lobe clutter artifacts, which can be identified and removed from the image data using dual apodization processing of the image data.

Abstract: The present invention relates to an ultrasound imaging system comprising an ultrasound probe having a transducer array configured to provide an ultrasound receive signal. The system further comprises a B-mode volume processing unit configured to generate a B-mode volume based on the ultrasound receive signal, and a B-mode image processing unit configured to provide a current B-mode image based on the B-mode volume. The system further comprises a memory configured to store a previously acquired 3D-vessel map. Also, the system comprises a registration unit configured to register the previously acquired 3D-vessel map to the B-mode volume and to select a portion of the 3D-vessel map corresponding to the current B-mode image. Further, the system comprises a display configured to display an ultrasound image based on the current B-mode image and the selected portion of the 3D-vessel map. The present invention further relates to a method for providing such ultrasound image with vessel information and a corresponding computer program.

Abstract: A method for planning ablation treatment using ultrasound data begins by identify pathology to be treated and one or more blood vessels proximate the treatment site in a medical diagnostic image. Ultrasonic Doppler velocity data is acquired from the flow within the vessels and the Doppler data is used to calculate the volume blood flow through the vessels. The thermal effect of the heat transported by this blood flow is considered in the planning of the ablation treatment.

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.

Abstract: Systems, devices, and methods for ultrasonic imaging by sparse sampling are provided. In one embodiment, an ultrasound imaging system comprises an array of ultrasound transducer elements, electronic circuitry in communication with the array of ultrasound transducer elements and configured to select a first receive aperture of the array comprising a plurality of contiguous ultrasound transducer elements and at least one non-contiguous ultrasound transducer element, and a beamformer in communication with the electronic circuitry. Each ultrasound transducer element of the first receive aperture is configured to receive reflected ultrasound echoes and generate an electrical signal representative of imaging data. The beamformer is configured to receive the electrical signals generated by the first receive aperture and apply different weight to the electrical signals generated by the contiguous ultrasound transducer elements and the electrical signal generated by the at least one non-contiguous ultrasound transducer element.
