Ultrasound systems, ultrasound scanners, and methods for determining venous congestion using ultrasound are disclosed. In some embodiments, the ultrasound machine includes a display device configured to display a user interface for the ultrasound machine and a processor. The processor is configured to cause the display device to display an ultrasound image that includes a vein, cause the display device to display a Doppler waveform for the vein, determine a vein type for the vein, determine, based on the vein type, classification waveforms, and cause the user interface to display the classification waveforms.

An ultrasound imaging system computes real time physiological parameters from measurements of anatomical features in ultrasound image data using a neural network to identify the location of the anatomical features. In one embodiment, cardiac parameters are computed from endocardial wall tracings in M-mode ultrasound image data that are identified by the neural network.

Ultrasound systems, ultrasound scanners, and methods for determining port health using ultrasound are disclosed. In some embodiments, the ultrasound system includes a display device configured to display a user interface for the ultrasound system and a wearable ultrasound scanner configured to be attached to a patient over a port that is placed inside the patient, where the port is configured to supply fluid to the patient or retrieve additional fluid from the patient. The ultrasound system also includes a processor system configured to generate, based on reflections of ultrasound received by the wearable ultrasound scanner, a health status of the port, and cause the user interface to display the health status of the port.

An ultrasound device, ultrasound system and method for performing the same with a multi-array scanner are disclosed. In some embodiments, an ultrasound device includes an array that has a plurality of rows of ultrasonic transducer elements, with the plurality of rows of transducer elements having a first row of transducer element sub-arrays and two or more outer rows of transducer element sub-arrays. The two or more outer rows have at least one row on two opposite sides of the first row of transducer element sub-arrays, and transducer element sub-arrays in first and second rows of transducer element sub-arrays of the one or more outer rows have heights and widths that are different from each other, with the height of each transducer element sub-array corresponding to a lateral dimension and the width corresponding to an elevation dimension perpendicular to the lateral dimension.

Systems and methods for simultaneous acquisition of pulsed-wave Doppler and color Doppler for retrospective analysis of cardiovascular function are disclosed. In aspects, imaging techniques are used for acquisition of raw partly processed ultrasound data. The ultrasound data is stored in its raw form, synchronized with a simultaneously acquired physiological signal. The stored ultrasound data can then be accessed and processed according to pulsed-wave Doppler and color Doppler imaging techniques to provide both a full frame, or sequence of frames of color Doppler images and a post-acquisition pulsed-wave Doppler signal of a sample volume at one or more locations within the acquisition area using the color Doppler image. Such locations can be selected automatically or by a user, and a pulsed-wave spectrum for the selected location is displayed. As the user moves the sample volume around, the pulsed-wave spectral data is recomputed and redisplayed.

Ultrasound methods and systems for measuring physiological properties are disclosed. The ultrasound methods and systems measure one or more characteristics of a vessel, such as vessel-wall displacement over time or blood-flow velocity over time, based on a pulse wave propagating through the vessel. In aspects, the characteristics are measured at two locations of the same vessel with a known distance between the two locations. A time shift between the measured characteristics at the two locations is calculated and used, along with the known distance, to determine one or more physiological properties, such as pulse-wave velocity or blood pressure. These physiological properties can be measured without the assistance of ECG data.

An ultrasound system includes an ultrasound scanner, a patient-worn registration system configured in at least a one-way communication with an interventional instrument, and a processor system. The processor system is configured to determine, based on the ultrasound data and positional data of the ultrasound scanner, a first location of the patient anatomy relative to the patient-worn registration system, determine, based on the at least a one-way communication, a second location of the interventional instrument relative to the patient-worn registration system; and determine, based on the first location and the second location, a third location of the interventional instrument relative to the patient anatomy. The processor system is configured to display a depiction of the patient anatomy based on the ultrasound data and a visual representation of the interventional instrument at the third location on a display device.

Systems and methods for producing ultrasound images are disclosed herein. In one embodiment, ultrasound image data are acquired in discrete time increments at one or more positions relative to a subject. Control points are added by a user for two or more image frames and a processor interpolates the location of the control points for image frames obtained at in-between times.

Systems and methods for anatomy-directed ultrasound are described. In some implementations, an anatomy-directed ultrasound system generates ultrasound data from an ultrasound scan of an anatomy, which is a bodily structure of an organism (e.g., human or animal). The system identifies organs represented in the ultrasound data and information associated with the organs including position and type of organ. Using this information, the system obtains or generates new ultrasound data that includes a region in which an item of interest is likely to be located. For example, the system can crop the original ultrasound data, refocus the ultrasound scan (e.g., by adjusting imaging parameters) to image the region that is likely to include the item of interest, or generate a weight map indicating the region. The anatomy-directed ultrasound system can increase accuracy and reduce the number of false positives in comparison to the number detected by conventional ultrasound systems.
