A guidance system is configured to detect a current pose of an ultrasound transducer and to determine a movement to achieve a desired pose associated with a desired view or imaging plane of a patients anatomy. In one embodiment, the guidance system includes a processor circuit in communication with the ultrasound transducer. The processor circuit is configured to: receive an input associated with a desired pose of the ultrasound transducer; receive ultrasound imaging data representative of a field of view of the ultrasound transducer in a current pose; determine a movement to align the current pose of the ultrasound transducer with the desired pose; and generate a graphical representation of the movement. The graphical representation shows both the current pose of the ultrasound transducer and the desired pose of the ultrasound transducer. The graphical representation is output to a display in communication with the processor circuit.

A universal ultrasound device having an ultrasound probe includes a semiconductor die; a plurality of ultrasonic transducers integrated on the semiconductor die, the plurality of ultrasonic transducers configured to operate a first mode associated with a first frequency range and a second mode associated with a second frequency range, wherein the first frequency range is at least partially non-overlapping with the second frequency range; and control circuitry configured to: control the plurality of ultrasonic transducers to generate and/or detect ultrasound signals having frequencies in the first frequency range, in response to receiving an indication to operate the ultrasound probe in the first mode; and control the plurality of ultrasonic transducers to generate and/or detect ultrasound signals having frequencies in the second frequency range, in response to receiving an indication to operate the ultrasound probe in the second mode.

A system for recording ultrasound images comprises a memory comprising instruction data representing a set of instructions and a processor configured to communicate with the memory and to execute the set of instructions. The set of instructions, when executed by the processor, cause the processor to receive a data stream of two dimensional images taken using an ultrasound transducer and determine from the data stream that a feature of interest is in view of the transducer. The set of instructions further cause the processor to trigger an alert to be sent to a user to indicate that the feature of interest is in view of the transducer, and send an instruction to the transducer to trigger the transducer to capture a three dimensional ultrasound image after a predetermined time interval.

An ultrasound diagnostic apparatus 1 includes an image acquisition unit 3 that generates an ultrasound image, an image recognition unit 9 that performs image recognition for the ultrasound image to calculate recognition scores, an index value calculation unit 10 that calculates index values of a plurality of parts on the basis of the recognition scores calculated for a predetermined number of ultrasound images, a part narrowing-down unit 11 that narrows down target parts for which part determination is to be performed, from the plurality of parts on the basis of the index values, and a part determination unit 12 that determines an imaging part of the subject on the basis of the recognition scores calculated by the image recognition unit 9 for the target parts narrowed down by the part narrowing-down unit 11.

Methods and systems are provided for adjusting settings of an ultrasound exam based on monitoring of the exam with an optical camera. One example method includes acquiring images of an ultrasound exam via a camera, analyzing the acquired images in real-time to build a spatial exam model, and adjusting settings of the ultrasound exam in real-time based on the spatial exam model.

During acquisition of an ultrasound image feed, ultrasound control data frames are acquired that may be interspersed amongst the ultrasound data frames. The control data frames may use consistent reference scan parameters, irrespective of the scanner settings, and may not need to be converted to image frames. The control data frames can be passed to an artificial intelligence model, which predicts the suitable settings for scanning the anatomy that is being scanned. The artificial intelligence model can be trained with a dataset containing different classes of ultrasound control data frames for different settings, where substantially all the ultrasound control data frames in the dataset are consistently acquired using the reference scan parameters.

Disclosed are 3D/4D contrast-enhanced ultrasound imaging (CEUS) apparatus, 3D/4D CEUS imaging methods and media. The method comprises: receiving an input for selecting a 3D/4D contrast-enhanced imaging mode; receiving an input for setting an imaging velocity including a first imaging velocity and a higher second imaging velocity; controlling the apparatus with an imaging parameter associated with the selected imaging mode and the set imaging velocity to achieve imaging with the selected imaging mode in the set imaging velocity, wherein an association between the imaging parameter and the imaging velocity allows that an amount of data required to generate images per volume using the first imaging velocity is greater than that using the second imaging velocity. In this way, a desired imaging mode and imaging velocity can be chosen freely and an imaging parameter can be selected pointedly, meeting real-time observation needed by doctors with limited data processing capability and various probes.

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.

A method for automatically selecting a calculation depth range upon measuring a property of a viscoelastic medium, the depth range being selected from P possible ranges, includes calculating, from the ultrasound signal acquired using a probe for elastography, the property of the viscoelastic medium in at least one of the P depth ranges as well as the distance between the probe and the wall of the viscoelastic medium; determining the validity of at least one of the P calculation depth ranges; determining the validity of the calculation of the property of the viscoelastic medium over the valid calculation depth range or ranges; selecting, from the values of the property of the viscoelastic medium the calculation of which is valid at the valid depth ranges, a depth range fulfilling a selection criterion.
