High volume rate 3D ultrasonic diagnostic imaging
A 3D ultrasonic diagnostic imaging system produces 3D display images at a 3D frame rate of display which is equal to the acquisition rate of a 3D image dataset. The volumetric region being imaged is sparsely sub-sampled by separated scanning beams. Spatial locations between the beams are filled in with interpolated values or interleaved with acquired data values from other 3D scanning intervals depending upon the existence of motion in the image field. A plurality of different beam scanning patterns are used, different ones of which have different spatial locations where beams are located and beams are omitted. In a preferred embodiment the determination of motion and the consequent decision to use interpolated or interleaved data for display is determined on a pixel-by-pixel basis.

Provided are an ultrasound system, an ultrasound probe, a control method of the ultrasound system, and a control method of the ultrasound probe capable of using various types of display terminals and causing the display terminal to perform processing according to computing power of the display terminal to be used.
An ultrasound system includes a display terminal and an ultrasound probe. The ultrasound probe has a reception circuit that generates a sound ray signal from a reception signal output from an oscillator array, an image generation unit that generates ultrasound image data from the sound ray signal, and a data selection unit that selects one of the ultrasound image data and intermediate data generated in a middle of generating the ultrasound image data, according to computing power of the display terminal, as data to be output to the display terminal. The display terminal to which the intermediate data is input generates the ultrasound image data from the intermediate data and displays an ultrasound image based on the ultrasound image data on the monitor.
Compressive sensing in forming ultrasound images
In an image compressing ultrasound system, for generating an imaging sample, delays are applied transducer-element-wise to respective time samples. The delayed samples are summed coherently in time, the coherently summed delays being collectively non-focused. An image is sparsified based on imaging samples and, otherwise than merely via said imaging samples, on angles (236) upon which respectively the delays for the generating of the imaging samples are functionally dependent. An image-compressing processor (120) may minimize a first p-norm of a first matrix which is a product of two matrices the content of one representing the image in a compression basis. The minimizing is subject to a constraint that a second p-norm of a difference between a measurement matrix and a product of an image-to-measurement-basis transformation matrix, an image representation dictionary matrix, and the matrix representing the image in the compression basis does not exceed an allowed-error threshold. The measurement matrix is populated either by channel data, or by output of a Hilbert transform applied to the channel data in a time dimension.

The stream of packets may be serialized. A plurality of decoding circuits may modulate the streams of packets to obtain spatial apodization.

The signal converter can condition a signal from the transducer element and convert the signal to a digital signal. The signal integrator can combine the digital signal into a transmission signal with at least a 10 Gigabit per second data rate.

Sold-state intravascular ultrasound (IVUS) imaging devices, systems, and methods are provided. Some embodiments of the present disclosure are particularly directed to flexible and efficient systems for focusing IVUS echo data received from transducers including polymer piezoelectric micro-machined ultrasound transducers (PMUTs). In one embodiment, an ultrasound processing system includes first and second aperture engines coupled to an engine controller, which provides aperture assignments to the first and second aperture engines. The aperture engines receive the assignment and a portion of A-line data, perform one or more focusing process on the received A-line data, and produce focused data in accordance with the aperture assignment. In some embodiments, once an aperture engine has produced focused data, the engine controller clears the aperture engine and assigns another aperture.
