摘要： The present invention is directed to a system and method which makes a phased array look like a curved array for purposes of performing spatial compounding calculations. In one embodiment, the phased array is treated as though it were a curved array by creating both a virtual apex and a virtual radius of curvature. Based on this transformation, standard spatial-compounding resampling tables can be used just as they are with curved arrays. In one embodiment, after the data is compounded to form the target image, certain data is removed prior to the actual display. This removed data represents data generated by virtual rays the prior to the physical skin line of the phased array.

摘要： The present disclosure is directed to systems and methods which allow for ultrasound parameter estimation to occur at specific advantageous sets of points in a two- or three-dimensional field of view within re-configurable, massively parallel, programmable architectures that can accommodate the input/output streaming, data movement or storage, and computation requirements. In one embodiment, a power efficient system is used for processing the data thereby increasing the ability of the system to be used for hand carried or mobile ultrasound applications. One aspect of the concepts discussed herein is the architectural aspects which provide the ability to simultaneously accept a large number of channels of data characterized by a continuous, simultaneous flow at high sample rates. The input data is routed at high rates to a distributed and large number of processing elements, memory, and connections for simultaneous parameter estimation at multiple points in the field of view. The ability to route the same data to multiple places enables high frame rates and allows for the streaming of data through the architecture.

摘要： A system and method are provided for producing a signal filter to block clutter. An embodiment includes the steps of acquiring samples of a clutter signal, calculating eigenvectors and eigenvalues representing the clutter signal, comparing said eigenvalues to a threshold to distinguish between eigenvectors representing clutter and those representing noise or signal, and determining filter parameters using the comparison results. Embodiments of the invention allow for optimization of wall filters for different anatomical applications, such as different body parts, in ultrasound imaging. The clutter signal may include Doppler data, and may be acquired using a pulsed wave (PW) mode, although the filter itself may be used in scanning Doppler color mode. The resulting wall filter is optimized for blocking clutter that is comparable to the clutter of the sampled clutter signal.

摘要： An ultrasound imaging system and method employs hardware and/or software to monitor values indicative of analog-to-digital converter (ADC) saturation for each channel as a function of depth. Any of a number of actions may be performed based on the monitored values. For example, analog amplification or TGC may be adjusted to enhance the use of a dynamic range of ADCs while reducing or eliminating ADC saturation. A TGC profile may be adjusted. An alert may be provided. A power consumption may be adjusted.
