Abstract: The following relates generally to systems and methods of transesophageal echocardiography (TEE) automation. Some aspects relate to a TEE probe with ultrasonic transducers on a distal end of the TEE probe. In some implementations, if a target is in a field of view (FOV) of the ultrasonic transducers, an electronic beam steering of the probe is adjusted; if the target is at an edge of the FOV, both the electronic beam steering and mechanical joints of the probe are adjusted; and if the target is not in the FOV, only the mechanical joints of the probe are adjusted.

Abstract: An end effector state estimation system for use in minimally invasive surgery (MIS) applications performs sensing and prediction algorithms to determine and visualize the state of an implantable therapeutic device during deployment. The end effector state estimation system includes a flexible elongate member, a therapeutic device coupled to a distal portion of the flexible elongate member, a sensor that measures at least one parameter related to the deployment state of the therapeutic device, and a processor. The processor receives image data from an imaging system representative of the therapeutic device positioned within the body cavity of the patient and the at least one parameter from the sensor, determines the deployment state of the therapeutic device based on the image data and the at least one parameter, outputs a graphical representation of the deployment state of the therapeutic device.

Abstract: An ultrasound system according to the present disclosure may include a beamformer configured to perform per-channel weighting on the RF signals received at each channel in order to reduce noise clutter in the image. For this purpose, the beamformer may receive at one or more channels associated with an active aperture, sets of receive signals associated with respective transmit beams that at least partially overlap. The beamformer may alter the receive space, e.g., to align the sets of receive signals to a common location (e.g., between the transmit beams) and generate a coherence-based weighting value that may be indicative of blockage. The coherence-based weighting value may be applied on a per-channel basis to the receive signals. The beamformer may also communicate the coherence metric to the controller for altering the transmit space. In some such examples, the power output to one or more elements of the array may be adjusted based upon the per-channel weighting value or determined blockage of the aperture.

Abstract: A controller (220) for determining a shape of an interventional medical device in an interventional medical procedure based on a location of the interventional medical device includes a memory (221) that stores instructions and a processor (222) that executes the instructions. The instructions cause a system (200) that includes the controller (220) to implement a process that includes obtaining (S320) the location of the interventional medical device (201) and obtaining (S330) imagery of a volume that includes the interventional medical device. The process also includes applying (S340), based on the location of the interventional medical device (201), image processing to the imagery to identify the interventional medical device (201) including the shape of the interventional medical device (201). The process further includes (S350) segmenting the interventional medical device (201) to obtain a segmented representation of the interventional medical device (201). The segmented representation of the interventional medical device (201) is overlaid (S360) on the imagery.

Abstract: User feedback on acquisition of ultrasound data may be provided to a user. The feedback may indicate a quality of the acquisition and/or the reliability of the measurements calculated from the ultrasound data, for example, the volume flow measurements calculated from Doppler data. Various quality factors such as a signal-to-noise ratio (SNR), motion, Doppler angle, vessel size, vessel depth, and/or variance in velocity values may be determined to provide an indication of quality of the acquisition. The quality factors may be provided individually or in combination. In some examples, one or more quantitative values of the quality factors may be provided. In some examples, one or more qualitative indications of the quality of the acquisition may be provided.

Abstract: 2019PF00643 32 ABSTRACT Disclosed is an ultrasound roadmap image generation system. The system includes a processor configured for communication with an ultrasound imaging device that is movable relative to a patient. The processor receives a first bi-plane or 3D image representative of a first volume within the patient and a second bi-plane or 3D image representative of a second volume within the patient. The processor then registers the first bi-plane or 3D image and the second bi-plane or 3D image to determine the motion between the first bi-plane or 3D image and the second bi-plane or 3D image. The processor then generates a 2D roadmap image of a region of interest by combining the first bi-plane or 3D image and the second bi-plane or 3D image, based on the determined motion; and outputs a screen display comprising the 2D roadmap image.
