The invention provides a method for deriving a biometric parameter of a fetal heart. The method includes acquiring a plurality of ultrasound images of a region of interest, wherein the region of interest comprises a fetal heart and comparing the plurality of ultrasound images to a predefined clinical view. A group of ultrasound images related to the predefined clinical view are selected based on the comparison, wherein the group of ultrasound images represents at least one cardiac cycle. An anatomical landmark of the fetal heart is detected within an ultrasound image of the group of ultrasound images and the anatomical landmark of the fetal heart is detected or tracked across the group of ultrasound images. A biometric parameter of the fetal heart is then determined based on the detected or tracked anatomical landmark from one or more ultrasound images of the group of ultrasound images.

Systems and methods are provided for use of analysis assistant during ultrasound imaging. Database may be acquired on a medical imaging technique during medical imaging based examination of a patient; and one or more medical images may be generated, based on the acquired dataset, and displayed. An end-result associated with at least one medical image may be provided, when triggered analysis assistance relating to the end-result associated with the at least one medical image may be provided. Providing the analysis assistance may include, automatically: identifying one or more intermediate steps performed or used in obtaining or determining the end-result; determining for each of the one or more intermediate steps corresponding information; and providing to a user the determined information associated with each of the one or more intermediate steps.

An ultrasonic diagnosis apparatus includes a position detector, and control circuitry. The position detector detects a position in a three-dimensional space of one of an ultrasonic image and an ultrasonic probe. The control circuitry uses a vivisection view defined in a three-dimensional space. The control circuitry associates a structure related to a subject included in the ultrasonic image with a structure included in the vivisection view using a position and orientation in a first three-dimensional coordinate system of the structure related to the subject included in the ultrasonic image and a position and orientation in a second three-dimensional coordinate system of the structure included in the vivisection view.

An ultrasound system includes: an ultrasound device having a two-dimensional array of ultrasound transducers; and a smartphone or tablet in operative communication with the ultrasound device. The ultrasound system is configured to: collect multiple sets of ultrasound data from multiple regions within the subject; detect fetal heartbeat signals and uterine contraction signals; monitor a fetal heartbeat signal among the fetal heartbeat signals by automatically steering an ultrasound beam to a first region among the multiple regions within the subject to collect first further ultrasound data from the first region based on a quality of the fetal heartbeat signal; and monitor a uterine contraction signal among the uterine contraction signals by automatically steering the ultrasound beam to a second region among the multiple regions within the subject to collect second further ultrasound data from the second region based on a quality of the uterine contraction signal.

The present disclosure provides using ultrasound technology and artificial intelligence to enhance MSR assessment by making the assessment more objective, reproducible, and recordable to allow a more precise and/or personalized approach to the medical practice of individual patients via using multiple ultrasound functions and artificial intelligence to improve the accuracy and consistency of assessing reflexes and allowing MSR data to be combined with other patient medical information for improved diagnosis and management of a patient's condition.

An ultrasonic device includes a driving circuit to provide drive power, a first transducer array to generate ultrasonic waves, the first transducer array being connected to receive power from the driving circuit, and a second transducer array to detect reflected or elicited ultrasonic waves incident on the device from a target and generate a signal based on those waves, the second transducer array being acoustically transmissive and disposed over the first transducer array such that the generated ultrasonic waves pass through the second transducer array. The second array is tuned to operate on top of the first. The functions of the two arrays may be reversed and the array tuned to operate with the first array receiving and the second array transmitting.

Ultrasound-based estimation of disease activity, such as for NAS or other activity index for NAFLD for liver disease, is provided. Ultrasound measures acoustic scatter and shear wave propagation parameters, such as measuring acoustic backscatter coefficient, shear wave velocity, and shear wave damping ratio. A score for the disease activity is determined from these scatter and shear wave propagation parameters. The physician may be assisted by relatively inexpensive and rapid ultrasound as compared to biopsy or MRI based scoring in scoring activity of a disease, such as NAFLD. Ultrasound imaging is more readily available and less expensive and MRI, and is non-invasive.

An ultrasound imaging system is for determining stroke volume and/or cardiac output. The imaging system may include a transducer unit for acquiring ultrasound data of a heart of a subject (or an input for receiving the acquired ultrasound data), and a controller. The controller is adapted to implement a two-step procedure, the first step being an initial assessment step, and the second being an imaging step having two possible modes depending upon the outcome of the assessment. In the initial assessment procedure, it is determined whether regurgitant ventricular flow is present. This is performed using Doppler processing techniques applied to an initial ultrasound data set. If regurgitant flow does not exist, stroke volume is determined using segmentation of 3D ultrasound image data to identify and measure the volume of the left or right ventricle at each of end systole and end-diastole, the difference between them giving a measure of stroke volume. If regurgitant flow does exist, stroke volume is determined using Doppler techniques applied to ultrasound data continuously collected throughout a cardiac cycle.

Embodiments of the present disclosure are directed to an vascular-dynamics-monitoring device (100) and methods for tracing a motion of boundaries of a vessel in a human body. The method features an automated gating of vessel walls' echoes in an ultrasound frame input to the vessel, accurate shift estimation for the gated vessel wall region, despite the presence of echoes from moving structures adjacent to the vessel and real-time trace of vessel walls' boundaries.

A method of displaying stereoscopic information related to an ultrasound sectional plane of a target object includes setting a line of interest on the ultrasound sectional plane of the target object based on a received input; obtaining an ultrasound signal of the ultrasound sectional plane of the target object along the set line of interest; converting the obtained ultrasound signal to represent the stereoscopic information in a three-dimensional manner; and displaying the stereoscopic information related to the ultrasound sectional plane of the target object.
