摘要： In one example in accordance with the present disclosure, an imaging device is described. The imaging device includes an array of transducers. Each transducer includes an array of piezoelectric elements. Each piezoelectric element transmits pressure waves towards an object to be imaged and receives reflections of the pressure waves off the object to be imaged. The imaging device also includes a transmit channel per one or more piezoelectric elements to generate the pressure waves and a receive channel per one or more piezoelectric elements to process the reflections of the pressure waves. The number of channels are selectively altered to control parameters such as power consumption and temperature.

摘要： The invention provides a method for generating a non-invasive measure of blood vessel rigidity for a subject. The method includes obtaining 2D ultrasound data and 3D ultrasound data of the blood vessel from a given measurement location. The 2D ultrasound data provides information relating to a movement of the blood vessel and the 3D ultrasound data provides information relating to a shape of the blood vessel. A motion of the blood vessel is then determined based on the movement of the blood vessel. The method then includes providing the determined motion of the blood vessel, the shape of the blood vessel and an obtained non-invasive pressure measurement to a biomechanical model. A measure of rigidity is then determined based on the biomechanical model.

摘要： A Multiple Aperture Ultrasound Imaging (MAUI) probe or transducer is uniquely capable of simultaneous imaging of a region of interest from separate apertures of ultrasound arrays. Some embodiments provide systems and methods for designing, building and using ultrasound probes having continuous arrays of ultrasound transducers which may have a substantially continuous concave curved shape in two or three dimensions (i.e., concave relative to an object to be imaged). Other embodiments herein provide systems and methods for designing, building and using ultrasound imaging probes having other unique configurations, such as adjustable probes and probes with variable configurations.

摘要： A diagnostic ultrasound system has a 2D array transducer which is operated with 1×N patches, patches which are only a single element wide. The “N” length of the patches extends in the elevation direction of a scanned 2D image plane, with the single element width extending in the lateral (azimuth) direction. Focusing is done along each patch in the elevation direction by a microbeamformer, and focusing in the lateral (azimuth) direction is done by the system beamformer. The minimal width of each patch in the azimuth direction enables the production of images highly resolved in the azimuthal plane of a 2D image, including the reception of highly resolved multilines for high frame rate imaging.

摘要： A system for deploying needles in tissue includes a controller and a visual display. A treatment probe has both a needle and tines deployable from the needle which may be advanced into the tissue. The treatment probe also has adjustable stops which control the deployed positions of both the needle and the tines. The adjustable stops are coupled to the controller so that the virtual treatment and safety boundaries resulting from the treatment can be presented on the visual display prior to actual deployment of the system.

摘要： For three-dimensional segmentation from two-dimensional intracardiac echocardiography imaging, the three-dimension segmentation is output by a machine-learnt multi-task generator. Rather than the brute force approach of training the generator from 2D ICE images to output a 2D segmentation, the generator is trained from 3D information, such as a sparse ICE volume assembled from the 2D ICE images. Where sufficient ground truth data is not available, computed tomography or magnetic resonance data may be used as the ground truth for the sample sparse ICE volumes. The generator is trained to output both the 3D segmentation and a complete volume (i.e., more voxels represented than in the sparse ICE volume). The 3D segmentation may be further used to project to 2D as an input with an ICE image to another network trained to output a 2D segmentation for the ICE image. Display of the 3D segmentation and/or 2D segmentation may guide ablation of tissue in the patient.

摘要： A method of full-field or “ping-based” Doppler ultrasound imaging allows for detection of Doppler signals indicating moving reflectors at any point in an imaging field without the need to predefine range gates. In various embodiments, such whole-field Doppler imaging methods may include transmitting a Doppler ping from a transmit aperture, receiving echoes of the Doppler ping with one or more separate receive apertures, detecting Doppler signals and determining the speed of moving reflectors. In some embodiments, the system also provides the ability to determine the direction of motion by solving a set of simultaneous equations based on echo data received by multiple receive apertures.

摘要： An apparatus that detects a tip of an interventional tool based on at least two ultrasound images reconstructed for different beam steering angles within a volumetric region that includes the tool. The apparatus includes an image processor. The image processor includes a tip detection module used to perform a tip tool detection procedure. The tip tool detection procedure involves identifying shadow regions of the tool in the at least two ultrasound images and determining the position of the tip of the tool within the volumetric region.

摘要： An ultrasound imaging system and method includes acquiring low-resolution volume data with an ultrasound probe during the process of acquiring high-resolution slice data of a plane with the ultrasound probe. The ultrasound imaging system and method includes displaying an ultrasound image on a display device based on the high-resolution slice data, generating a low-resolution volume based on the low-resolution volume data, and implementing, with a processor, a neural network to calculate guidance information based on the low-resolution volume. The ultrasound imaging system and method includes automatically performing an action with the processor based on the guidance information.
