The pumping of arterial blood into the cerebral spinal fluid (CSF) of a patient's brain creates cycle pressure undulations in the CSF and the brain itself. Brain injuries can create abnormal changes in this pressure waveform. Accordingly, the disclosed technology includes an ultrasound based device for monitoring this brain movement in the CSF (“pulsatility”) to diagnose and monitor brain injury.

A guidance system providing real-time, three-dimensional (3D) augmented reality (AR) feedback guidance to a user of an equipment system, to achieve improved procedural outcomes in the use of the equipment system.

Methods for developing a machine learning model of a neural network for classifying medical images using a medical imaging system such as an ultrasound system. The methods involve capturing images during a first medical procedure, analyzing the images for the presence of one or more features, labeling the images as belonging to one or more classes, splitting the labeled images into a training set and a validation set. Training and validation processes are then performed, and the machine learning model may be used when training process metrics and validation process metrics for the training and validation processes are within acceptable thresholds.

For phase inversion-based ultrasound imaging with a transmit and receive circuit at an array, a unipolar transmitter is used to reduce the number of high voltage wires. Rather than adding a T/R switch or increasing connections by connecting the receive amplifier to a different electrode than the transmitter, two different receive paths from the element to the receive amplifier are provided. One path is used where the unipolar transmitter ends in one state (e.g., 0V), and the other path is used where the unipolar transmitter ends in another state (e.g., Vtx).

An ultrasound system (100) for providing an ultrasound image of a volumetric region comprising a region of interest (12) comprising: a probe (10) having an array of CMUT transducers (14); a beamformer (64) coupled to the array and adapted to control the ultrasound beam steering and provide an ultrasound image data of the volumetric region; a transducer frequency controller (62) coupled to the beamformer and adapted to vary operation frequencies of the CMUT transducers within the frequency range, which frequency controller is arranged to set the operation frequency to a first frequency for the ultrasound beam steered in the volumetric region and to set the operation frequency to a second frequency for the ultrasound beams steered within the region of interest, the second frequency being higher than the first frequency; wherein the system further comprises an interferer analyzer (69) coupled to the transducer frequency controller (62), said interferer analyzer is adapted to vary at least one of beam steering parameters when the second frequency is above a threshold frequency value so as to mitigate a quality reduction of the ultrasound image due to the use of frequencies above the threshold.

A medical guidance system providing real-time, three-dimensional (3D) augmented reality (AR) feedback guidance to a novice user of medical equipment having limited medical training, to achieve improved diagnostic or treatment outcomes.

A system includes an energy source configured to generate therapeutic energy, a treatment probe, an ultrasound imaging device configured to generate ultrasound images, a second tracking sensor configured to track a location of the ultrasound imaging device, and a tracking system configured to receive location information from the first and second tracking sensors and to overlay the ultrasound images with a graphical representation of the treatment probe on a display based on the location information. The treatment probe includes an antenna configured to treat tissue with the therapeutic energy and a first tracking sensor integrated in the antenna and configured to track a location of a distal tip of the antenna.

Methods for providing real-time, three-dimensional (3D) augmented reality (AR) feedback guidance to a user of a medical equipment system to achieve improved diagnostic or treatment outcomes in the use of the medical equipment. The methods involve providing real-time position-based 3D AR feedback and real-time outcome-based 3D AR feedback to the user via an augmented reality user interface (ARUI). The feedback may be provided to the user via a head mounted display (HMD).

In accordance with an aspect of the present disclosure, there is provided an ultrasonic diagnostic apparatus comprise an ultrasonic probe configured to transmit an ultrasound signal to an object and receive a response signal reflected from the object, an image generator configured to create an ultrasound image of the object based on a first ultrasound signal and a first response signal and a controller configured to control transmission order and transmission intervals of the ultrasound signal and estimate a position of the ultrasonic probe based on a second ultrasound signal and a second response signal. The ultrasonic diagnostic apparatus in accordance with embodiments of the present disclosure, the current position of the ultrasonic probe is estimated using an ultrasound signal transmitted for creation of an ultrasound image without attachment of an extra sensor, so the position of the ultrasonic probe may be estimated more economically and effectively.

Aspects of the technology described herein related to monitoring fetal heartbeat and uterine contraction signals. An ultrasound system may be configured to sweep a volume to collect ultrasound data, detect a fetal heartbeat and/or uterine contraction signal in the ultrasound data, and automatically steer an ultrasound beam to monitor the fetal heartbeat and/or uterine contraction signal. The ultrasound system may be further configured to determine a location where the fetal heartbeat and/or uterine contraction signal is detectable or detectable at a highest quality. The ultrasound system may include a wearable ultrasound device, such as an ultrasound patch coupled to a subject. The wearable ultrasound device may have a two-dimensional array of ultrasonic transducers capable of steering ultrasound beams in three dimensions.
