Diagnostic apparatus includes a plurality of antennas, which are configured to be disposed at different, respective locations on a thorax of a living body so as to direct radio frequency (RF) electromagnetic waves from different, respective directions toward a heart in the body and to output RF signals responsively to the waves that are scattered from the heart. Processing circuitry is configured to process the RF signals over time so as to provide a multi-dimensional measurement of a movement of the heart.
SYSTEMS AND METHODS FOR SCAN PLANE PREDICTION IN ULTRASOUND IMAGES
The current disclosure provides systems and methods for providing guidance information to an operator of a medical imaging device. In an embodiment, a method is provided, comprising training a deep learning neural network on training pairs including a first medical image of an anatomical neighborhood and a second medical image of the anatomical neighborhood as input data, and a ground truth displacement between a first scan plane of the first medical image and a second scan plane of the second medical image as target data; using the neural network to predict a displacement between a first scan plane of a new medical image of the anatomical neighborhood and a target scan plane of a reference medical image of the anatomical neighborhood; and displaying guidance information for an imaging device used to acquire the new medical image on a display screen.
High Fidelity Doppler Ultrasound Using Vessel Detection For Relative Orientation
Dynamically adjusting ultrasound-imaging systems include an ultrasound probe, a console, and a display screen. The ultrasound probe includes an array of ultrasonic transducers that, when activated, emit generated ultrasound signals into a patient, receive reflected ultrasound signals from the patient, and convert the reflected ultrasound signals into corresponding electrical signals for processing into ultrasound images. The console is configured to execute instructions for defining an orientation of an image plane with respect to a blood vessel based on a shape a blood image and further with respect to a direction of blood flow within the blood vessel via doppler ultrasound. The orientation of image plane may be defined by a comparison of an ultrasound image with corresponding ultrasound images stored in memory. The system may automatically reorient the image plane to align with the blood vessel.

Optoacoustic imaging systems and methods with enhanced safety
An optoacoustic system and method for providing enhanced laser safety includes a laser light source, a control and processing system, a laser override, and an array of optoacoustic transducers. The laser light source is capable of generating a laser light pulse upon receiving a laser light source trigger. The control and processing system is configured to generate a laser light source trigger, to receive and process ultrasound data, and to control operation of the optoacoustic system. The control and processing system determines whether received ultrasound data reflects acoustic coupling between the transducer array and the volume. The laser override is configured to automatically prevent the generation of a laser light pulse if received ultrasound data does not reflect acoustic coupling between the optoacoustic transducer array and the volume.
Ultrasound based tracking system using triangulation and spatial positioning with detachable reference frame and ultrasound emitters
The present invention relates to an ultrasound-based system for localizing a medical device within the field of view of an ultrasound imaging probe. A localization system is provided that includes at least three ultrasound emitters that are arranged on a frame; and a position triangulation unit. The frame is adapted for attachment to an ultrasound imaging probe. The position triangulation unit determines a spatial position of the ultrasound detector relative to the at least three ultrasound emitters based on signals received from an ultrasound detector that is attached to the medical device. The frame includes a detachable reference volume comprising a background volume and an inclusion or void. When the detachable reference volume is attached to the frame and the frame is attached to the ultrasound imaging probe the inclusion or void provides a corresponding image feature within the field of view of the ultrasound imaging probe for use in calibrating the field of view of the ultrasound imaging probe with the coordinate system of the localization system.
