An ultrasound imaging system comprising a processor circuit in communication with an ultrasound transducer array, the processor circuit configured to receive, from the ultrasound transducer array, a set of images of a three-dimensional (3D) volume of a patients anatomy including an anatomical feature; obtain first measurement data of the anatomical feature in a first image of the set of images; generate second measurement data for the anatomical feature in one or more images of the set of images by propagating the first measurement data from the first image to the one or more images; and output, to a display in communication with the processor circuit, the second measurement data for the anatomical feature.

The invention relates to ultrasound imaging method and apparatus suitable for minimally invasive ultrasound diagnostic devices in cardiac ablation monitoring and in tumor ablation monitoring. The present invention proposes an assembly of forward and side-facing transducers and a system of embedded forward and side-facing transducers in apertures on surfaces of the assembly. This provides control of the acoustic properties of the transducer and improved ablation monitoring when the assembly is incorporated in a medical device.

Systems and methods are provided for enhanced heart medical imaging operations, particularly as by incorporating use of artificial intelligence (AI) based fetal heart functional analysis and/or real-time and automatic ejection fraction (EF) measurement and analysis.

The disclosure provides wearable cardiac arrest detection and alerting device that incorporates a non-invasive sensor based on optical and/or electrical signals transmitted into and received from human tissue containing blood vessels, and that transcutaneously quantifies the wearer's heart rate. The heart-rate quantification enables the detection of the absence of any heart beat by the wearable detection and alerting device indicative of the occurrence of a cardiac arrest, wherein the heart is no longer achieving effective blood circulation in the individual wearing the device. The display on the wearable cardiac arrest detection and alerting device may include the elapsed time since the time of detection of a heart rate that is below a predetermine lower limit value, i.e., the detected occurrence of a cardiac arrest event.

Ultrasound devices are disclosed. The ultrasound devices have an elevational dimension. Different percentages of the aperture of the ultrasound device corresponding to different percentages of the elevational dimension are utilized in different applications. The resolution of imagine may be adjusted in connection with usage of different percentages of the aperture.

The present invention relates to the field of ultrasounds and imagining of the coronary blood flow of the heart. Patients with coronary microvascular dysfunction (CMD) have poor prognostic with significantly higher rates of cardiovascular events, including hospitalization for heart failure, sudden cardiac death, and myocardial infarction (MI). Despite the urgent clinical need, there are no non-ionizing and non-invasive techniques available in clinic to directly visualize the coronary microvasculature and assess the local coronary microvascular system. Flow imaging remains a difficult task to perform in the heart because of the fast movements of this organ. In order to overcome the limitations of actual imaging methods for the coronary blood flow, the inventors proposed an ultrasound ultrafast imaging method that automatically detect the time periods in which the myocardium velocity is low and estimate the coronary flow velocity and the tissue velocity from the same data acquisition.

An ultrasound imaging system may acquire short and/or undersampled radiofrequency ensembles for generating color Doppler images. The ultrasound imaging system may process the short and/or undersampled ensembles to simulate color Doppler images acquired from long radiofrequency ensembles. In some examples, the ultrasound imaging system may include a neural networks to process the ensembles. In some examples, the neural network may include two serial neural networks. In some examples, during training of the neural network, a power Doppler-based flow mask may be used on the output of the neural network. In some examples, during training of the neural network, an adversarial loss may be used on the output of the neural network.

The present invention related to an ultrasound imaging system win which the scan head includes a beamformer circuit that performs far field subarray beamforming or includes a sparse array selecting circuit that actuates selected elements. When using a hierarchical two-stage or three-stage beamforming system, three dimensional ultrasound images can be generated in real-time. The invention further relates to flexible printed circuit boards in the probe head. The invention furthermore related to the use of coded or spread spectrum signaling in ultrasound imagining systems. Matched filters based on pulse compression using Golay code pairs improve the signal-to-noise ratio thus enabling third harmonic imaging with suppressed sidelobes. The system is suitable for 3D full volume cardiac imaging.

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 apparatus includes a sensor which guides a decision that acoustic coupling quality is insufficient, the apparatus issuing a user alert upon the decision.

The invention provides an ultrasound system including an ultrasound transducer array and a processor. The ultrasound transducer array comprises a plurality of transducer elements adapted to conform with a subjects body. Further, at least two ultrasound transducer elements of the plurality of transducer elements are adapted to acquire a plurality of ultrasound signals from a region of interest at different orientations relative to said region of interest. The processor is adapted to receive ultrasound signals acquired by the ultrasound transducer array. The processor is further adapted to partition the plurality of ultrasound signals according to a signal depth and, for each ultrasound signal partition, calculate a Doppler power. For each ultrasound signal, the processor identifies a depth of a fetal heartbeat based on the Doppler power of each ultrasound signal partition and identifies a fetal heart region based on the identified fetal heartbeat and a location of the at least two ultrasound transducers.
