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.

Apparatuses, systems and methods for providing acquisition feedback

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.

Ultrasonic imaging by sparse sampling and associated devices, systems, and methods

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.

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.

Ultrasound system and method for breast tissue imaging

The present disclosure describes ultrasound imaging systems and methods that may be used to image breast tissue. An ultrasound imaging system according to one embodiment may include a user interface comprising a display, a processor operatively connected to the user interface, and memory comprising processor-executable instructions, which when executed by the processor cause the user interface to display a first ultrasound image of a breast on the display and receive an indication of a first region of interest (ROI) in the first ultrasound image. The memory may include instructions to further cause the user interface to display a second ultrasound image of the breast on the display and receive an indication of a second region of interest in the second ultrasound image. The processor may be configured to determine locations of the first and second regions of interest based on probe position data associated with the first and second images, respectively and cause the user interface to display a visual indication of a relative distance between the first and second regions of interest if the relative distance is less than or equal to a predetermined amount.

Ultrasound system and method for breast tissue imaging and annotation of breast ultrasound images

An ultrasound system includes a 3D imaging probe and a needle guide which attaches to the probe for guidance of needle insertion into a volumetric region which can be scanned by the 3D imaging probe. The needle guide responds to the insertion of a needle through the guide by identifying a plane for scanning by the probe which is the insertion plane through which the needle will pass during insertion. The orientation of the insertion plane is communicated to the probe to cause the probe to scan the identified plane and produce images of the needle as it travels through the insertion plane.

Ultrasound imaging system and method for image guidance procedure

An ultrasound system and method are described for acquiring standard views of the fetal heart simultaneously with real-time imaging. A matrix array probe is manipulated until a first standard view such as a 4-chamber view is acquired. The first standard view image is matched to its corresponding plane in a fetal heart model. From the matched plane of the heart model, the orientations of the other standard views are known from the geometrical relationships of structures within the heart model. This orientation information is used to control the matrix array probe to automatically scan the planes of all of the standard views simultaneously in real-time.

Automatic positioning of standard planes for real-time fetal heart evaluation

An ultrasound system with a matrix array () probe () operable in the biplane mode is used to assess stenosis of a blood vessel by simultaneously displaying two color Doppler biplane images () of the vessel, one a longitudinal cross-sectional view () and the other a transverse cross-sectional view (). The two image planes intersect along a Doppler beam line () used for PW Doppler. A sample volume graphic (SV) is positioned over the blood vessel at the peak velocity location in one image, then positioned over the blood vessel at the peak velocity location in the other image. As the sample volume location is moved in one image, the plane and/or sample volume location of the other image is adjusted correspondingly. Spectral Doppler data () is then acquired and displayed from the sample volume location.

Automated biplane-PW workflow for ultrasonic stenosis assessment

A system and method for image registration includes tracking () a scanner probe in a position along a skin surface of a patient. Image planes corresponding to the position are acquired (). A three-dimensional volume of a region of interest is reconstructed () from the image planes. A search of an image volume is initialized () to determine candidate images to register the image volume with the three-dimensional volume by employing pose information of the scanner probe during image plane acquisition, and physical constraints of a pose of the scanner probe. The image volume is registered () with the three-dimensional volume.
