摘要： Rather than using a coaxial cable, a twisted pair of wires is provided for each element-to-beamformer connection. Differential mode signals are transmitted between the transducer element and the respective channel. A multi-layer element is used for operation with the differential mode signals. In catheters or other probes, coaxial cables are not used. Using differential mode signals over twisted pairs allows reduction or rejection of common mode cross-talk and/or interference.

摘要： A multi-layer transducer operates with only one system channel per element. Passive switching connects the layers differently for transmit than for receive operation, such as connecting two layers in parallel for transmit and in series for receive. Any passive switching may be used, such as current and voltage limiting circuits. Tuning may be passively switched. Different tuning circuits are passively switched as a function of voltage level between transmit and receive operations.

摘要： Endocavity and invasive catheter transducers for four-dimensional or other imaging are provided. A two-dimensional or other multi-dimensional array of elements is connected with a minimum number of conductors to an imaging system. One or more conductors are used to select an aperture, such as selecting one or more rows of elements for activation. Along a different axis, such as an orthogonal axis, elements are used to image a planar region. By electronically switching the selected aperture, different planes are rapidly imaged. A matrix configuration of electrodes, such as using column electrodes for phased array imaging and row electrodes for selecting an elevation aperture allows for rapid acquisition of ultrasound data.

摘要： A transmit beamformer includes multiple transducers, each responsive to a respective transmit waveform to produce a respective transducer waveform. A transmit waveform generator generates the transmit waveforms, and the transmit waveform each include multiple frequency components. Progressively higher frequency components of the transmit waveform are timed to cause corresponding progressively higher frequency components of the transducer waveforms to focus along a line at progressively shorter ranges. In this way, a frequency dependent line focus is achieved.

摘要： An irregular ultrasound sampling grid is reconstructed to a three-dimensional grid for imaging. Volume data acquired with a helix transducer includes a fractional offset of data spaced along one dimension, resulting in the irregular ultrasound sampling grid. To determine a voxel value for a grid point on a uniform grid, two adjacent planes are identified. The sample locations in the two planes are not aligned, being on the irregular ultrasound sampling grid. Hardware acceleration devices, such as a graphics processing unit, perform bilinear interpolation in each of the planes. The data of each plane is interpolated to the proper global azimuth-range coordinate corresponding with the grid point. The bilinearly interpolated values from each plane are then linearly interpolated to the grid point.

摘要： A transducer array includes two or more sub-arrays that move relative to each other. Position sensors on each of the sub-arrays provide spatial coordination for beamforming and/or image forming to yield extended field of view and high image resolution. The adaptable transducer array, such as mounted on a flexible transducer housing, allows the array to better conform to the patient during internal or external use.

摘要： A transducer array is connected with a catheter housing. As the transducer array is rotated, the catheter housing also rotates. As a result, at least a portion of the catheter housing twists about a longitudinal axis. By applying rotation in a controlled way, such as with a motor, a plurality of two-dimensional images for three-dimensional reconstruction may be obtained. The rotation of the catheter housing may limit the total amount of rotation of the array, such as rotating the array through a 90 degree or less amount of rotation about the longitudinal axis. The housing of the catheter is formed with a soft section. The softer material allows for a greater amount or increased ease for twisting the catheter.

Simultaneous and sequential compound point, line and combination point and line focusing is used with harmonic receive processing. Ultrasonic energy focused at multiple depths is transmitted at the target. The target may or may not include contrast agents. In either case, echoes of the transmissions at one or more fundamental center frequencies are received at harmonics of the fundamental frequencies.
