Aspects of the technology described herein relate to techniques for guiding an operator to use an ultrasound device. Thereby, operators with little or no experience operating ultrasound devices may capture medically relevant ultrasound images and/or interpret the contents of the obtained ultrasound images. For example, some of the techniques disclosed herein may be used to identify a particular anatomical view of a subject to image with an ultrasound device, guide an operator of the ultrasound device to capture an ultrasound image of the subject that contains the particular anatomical view, and/or analyze the captured ultrasound image to identify medical information about the subject.

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 feedback does not include a grayscale depiction of the image data. Coordinate system transformations corresponding to respective comparisons may be computed. The selecting may be based upon and dynamically responsive to content of imaging being dynamically acquired via the probe.

An ultrasound imaging apparatus (200, 600) may include at least one controller (210, 610) which may be configured to: acquire ultrasound data of an anatomical region-of-interest (ROI), the ultrasound data including at least two frames acquired at different times over an interval of time as a push force is applied to induce movement in the anatomical ROI; determine a correlation between at least two of the acquired frames and form corresponding correlation coefficients; generate a correlation coefficient (CC) map based upon the determined correlation information between the at least two frames; and distinguish fluid from tissue within the CC map based upon a comparison of the correlation coefficients with at least one threshold value.

A system and method for compiling a clinically logical medical dossier for a patient. A list of medical conditions can be determined for the patient. A plurality of medical imaging records for the patient can be identified, and each record can be assigned to one of the conditions. A timeline of condition-specific imaging records can then be generated for each condition. A condition can be selected and the timeline of condition-specific imaging records for the selected condition can then be displayed.

An ultrasound diagnostic apparatus includes: an ultrasound probe; an imaging unit that transmits and receives an ultrasound beam to and from a subject using the ultrasound probe and converts a received signal output from the ultrasound probe into an image to generate an ultrasound image of the subject, according to set imaging conditions; a part determination unit that determines an imaging part of the subject using the ultrasound image generated by the imaging unit; a determination result storage unit that stores determination results corresponding to a plurality of frames obtained by the part determination unit; and a determination result integration unit that integrates the determination results corresponding to the plurality of frames stored in the determination result storage unit and outputs an integrated determination result.

A method and a system for registering real-time intra-operative image data of a body to a model of the body, the method comprising, segmenting a plurality of image data of the body obtained using a pre-operative imaging device; constructing the model of the body from the segmented plurality of image data; identifying one or more landmark features on the model of the body; acquiring the real-time intra-operative image data of the body using an intra-operative imaging device; and registering the real-time intra-operative image data of the body to the model of the body by matching one or more landmark features labelled on the real-time intra-operative image data to one or more corresponding landmark features on the model of the body, wherein the one or more landmark features comprises a superior and an inferior pole of the body.

A first transducer (20) transmits a first acoustic field (22) at a first frequency into a region (24) of a medium (26), generating oscillatory motion of scatterers (28) disposed in the region. A second transducer (30) transmits acoustic pulses (32, 34) into the region, and receives respective echoes of each pulse scattering off an oscillating scatterer in the region. The pulses are synchronized with the first acoustic field such that a first pulse scatters off the oscillating scatterer when the scatterer is at a first displacement extremum (36), and a second pulse scatters off the oscillating scatterer when the scatterer is at a second displacement extremum (38) that is opposite the first displacement extremum. A computer processor (29) extracts a time shift between the received echoes, calculates a displacement amplitude of the scatterer, and outputs an indication of the displacement amplitude of the scatterer. Other applications are also described.

An ultrasound transducer includes a transducer array having a plurality of transducer elements. The transducer array has a first side and a second side. Further, one or more ground electrodes are disposed on the first side of the transducer array, and one or more signal electrodes are disposed on the second side of the transducer array. Moreover, an acoustic backing structure is operatively coupled to the plurality of transducer elements of the transducer array. Also, a plurality of electrical traces is routed on a surface of the acoustic backing structure and operatively coupled to at least one of the one or more signal electrodes and one or more ground electrodes.
