摘要： An apparatus (402) includes an analog beamformer (414) that receives a set of analog RF signals. The set of analog RF signals are generated by a corresponding set of transducer elements (406) receiving ultrasound echo signals. The analog beamformer includes a delay network (416) with a set of phase shifting networks (506). Each phase shifting network of the set of phase shifting networks processes a different one of the analog RF signals of the set of analog RF signals. Each phase shifting network of the set of phase shifting networks adds a delay to the corresponding analog RF signal, producing a set of delayed analog RF signals that are aligned in time. The set of phase shifting networks does not use an inductive element to determine or add the delays. The analog beamformer further includes a summer (504) that sums the delayed analog RF signals, producing an analog beam sum.

摘要： The present disclosure in one or more embodiments provides a scan converter, an ultrasound diagnostic apparatus, and a method capable of performing real-time interpolation without directional distortion. An embodiment of the present disclosure prevents directional distortion of velocity data by performing vector interpolation by using a weight according to distances of four adjacent complex signals in color flow-mode (C-mode) and achieves real-time scan conversion by constructing a lookup table for vector interpolation.

摘要： Display or pixel values are scan converted from ultrasound data on the fly. As each pixel is to receive display values, the display value is determined. Scan conversion is performed sequentially, with each new value being determined in synchronization with reading display values out to the display. Rather than storage in a raster buffer, scan converted display values are output to the display while other display values for a same image are being converted.

摘要： Beamforming for N elements in performed in log(N) steps of complexity O(N). The signals measured at each element are treated as a receive beam formed by that element with a beam width equal to the element pattern or the width of the transmit illumination. In each of multiple stages, the number of elements is halved by effectively doubling the pitch. The number of beams formed by each element is doubled by narrowing the beam width by a factor of 2 in sin(θ). Since steering and focusing are separated, a single set of delays are applied to each element signal individually prior to the multi-stage beam forming for each finite depth. The data is in a sector format, but by using two beamforming steps, data in a Vector® format is provided.

摘要： A method of forming ultrasound image is disclosed. A first, image data described with a cylindrical coordinate in a space domain is formed from receiving signals provided by a probe. A scan-converted Fourier transformation described with a rectangular coordinate in a frequency domain is applied to the first image data to form second image data described with the rectangular coordinate in a frequency domain. An inverse Fourier transformation is applied to the second image data to form a third image data described with the rectangular coordinate in the space domain. An ultrasound image is formed with the third image data.

摘要： A method and apparatus are provided for reducing distortion in a dynamically delayed digital sample stream of an imaging system. The method includes the steps of delta-sigma modulating an input analog signal of the imaging system at a frequency above the Nyquist frequency of the input analog signal to generate a digital sample stream and changing a length of the sample stream to delay a portion of the sample stream while maintaining synchronism between a delta-sigma modulator and a demodulator of the system.

摘要： An ultrasound imaging system includes a transducer, an ultrasound module, and a computer. The ultrasound module provides signal pre-processing and is highly programmable. The ultrasound module has several independently programmable functional units. The computer performs real-time scan conversion, display, data collection, user interface and input and output data exchange. The operational mode of the ultrasound module can be set under software control from the computer. The ultrasound imaging system is versatile, software-upgradable, and can perform a wide range of imaging applications in real-time. Several ultrasound imaging systems can be integrated as clients in a network of ultrasound devices having a client/server architecture for archiving, reporting and remote-control purposes.
