摘要： A system (502) includes an elongate ultrasound imaging probe (504) with a long axis and a top side that extends along the long axis. The elongate ultrasound imaging probe includes an elongate tubular handle (606; 1606), a head (1608), an elongate tubular shaft (608; 1610) between the elongate tubular handle and the head, and a transducer array (514) disposed in the head and configured to transmit in a sagittal plane, which is a plane that cuts through the long axis of the elongate tubular shaft, only in a direction extending out from the top side. The elongate tubular handle is both not centered on the elongate tubular shaft and not shifted down in the sagittal plane away from the top.

摘要： A system includes an image guidance system with a memory with computer executable instruction, a processor configured to execute the computer executable instructions, and a display. The computer executable instructions cause the processor to: receive a three-dimensional model of vasculature from an ultrasound imaging system, receive a real-time optical feed of an interior of a cavity from an optical camera-based guidance system, receive a first tracking signal indicative of a first spatial location of a probe of the ultrasound imaging system, receive a second spatial location of the optical camera-based guidance system, and overlay the optical feed with the three-dimensional model based on the first and second tracking signals. The display is configured to visually present the optical feed with the three-dimensional model overlaid thereover.

摘要： An ultrasound imaging system includes a transducer array (102) with a plurality of transducer elements (106) configured to transmit an ultrasound signal, receive echo signals produced in response to the ultrasound signal interacting with stationary structure and flowing structure, and generate electrical signals indicative of the echo signals. The system further includes a beamformer (112) configured to process the electrical signals and generate sequences, in time, of beamformed data. The system further includes a filter (118) configured to process the beamformed data, and remove or replace a set of frequency components based on a threshold, producing corrected beamformed data. The system further includes a flow processor (120) configured to estimate a velocity of flowing structure from the corrected beamformed data. The system further includes a rendering engine (224) configured to display the flow velocity estimate on a display (124).

摘要： An ultrasound imaging system include a console with transmit circuitry configured to generate an excitation electrical pulse that excites transducer elements of a probe to produce an ultrasound pressure field and configured to receive an echo signal generated in response to the ultrasound pressure field interacting with tissue. The console further includes receive circuitry configured to convert the echo signal into an electrical signal, and an echo processor configured to generate a live ultrasound image based on the electrical signal into. The console further includes a tracking processor configured to extract, in real-time, a feature common to both the live ultrasound image and previously generated volumetric image data from at least the live ultrasound image, and register, in real-time, the live ultrasound image with previously generated volumetric image data based on the common feature extracted in real-time to create the fused image. A display displays the fused image.

摘要： A probe includes an articulating member with at least two vertebrae elements sequentially arranged along a long axis of the elongate ultrasound imaging probe. The articulating member includes pivots located between the at least two vertebrae elements. The pivots are disposed off-center relative to the at least two vertebrae elements. The pivots are spatially oriented to provide a pivot point for a different articulation direction of a vertebra element. The probe further includes a plurality of guides, including at least one guide for each of the respective different pivot directions. The probe further includes an actuator with a set of controls, each control configured to actuate a different pair of the plurality of guides for controlling opposing articulation directions, wherein the actuator reduces stress induced on at least one of a pushed guide or a non-activated guide, wherein the stress is induced in response to the actuator pulling a guide.

摘要： A method for determining pressure gradients with ultrasound data includes acquiring ultrasound data of a vessel and generating a velocity vector profile for flow in the vessel with the ultrasound data. The method further includes computing an acceleration with the velocity vector profile. The acceleration includes at least a temporal acceleration, and computing the temporal acceleration includes reducing noise from the velocity vector profile and determining the temporal acceleration from the noise-reduced velocity data. The method further includes determining the pressure gradients with the computed acceleration.

摘要： An ultrasound imaging system (300) includes one or more transducing elements (304). The ultrasound imaging system further includes a system controller (330) configured to control the one or more transducing elements to receive for a predetermined time duration without first transmitting and produce a noise only signal. The system controller is further configured to control the one or more transducing elements to transmit a set of pulses which causes the one or more transducing elements to transmit a pressures wave and receive echo waves generated in response to the transmitted pressures wave and produce an echo plus noise signal indicative thereof. The ultrasound imaging system further includes a noise processor (320) that compensates the echo plus noise signal with the noise only signal, creating a denoised signal, which is displayed.
