摘要： An ultrasonic diagnostic imaging system is described which quantifies regurgitant flow through a plurality of pinhole leaks or a slit leak of a mitral valve. A plurality of orifice locations of a leaking valve are identified and Doppler values obtained from a flow velocity field proximal each orifice. The Doppler values of each flow velocity field vectorially relating to the orifice location are processed to produce a measure of flow through the orifice. The flow measurements for a plurality of such orifices are summed to produce a quantified measure of regurgitant flow through a plurality of pinhole leaks or along a slit leak.

摘要： An ultrasound flow measurement system converts each of plural groups of reflection sample values from scatterers, into baseband complex data values and enables a velocity determination from just two lag samples. A cross correlation function derives a first cross-correlation value between a first set of complex data values that are derived at a first common sample time, during succeeding transmit events, and a second set of complex data values that are derived at a second common sample time, during succeeding transmit events. A second cross-correlation function derives a second cross-correlation value between the first set of complex data values and a third set of complex data values that are derived at the common second sample time. A local oscillator synchronizes both the baseband conversion and cross-correlation operation, and exhibits a rate of change of phase per sample time. A processor relates the rate of change of phase of the local oscillation signal, the first cross-correlation value and the second cross-correlation value to derive the velocity of the ultrasound scatterers. In particular, the first and second cross-correlation values enable establishment of a linear function defining the phase of the cross-correlation function of the complex data values. The rate of change of phase of the local oscillation signal enables establishment of a further linear function. The intersection of the two linear functions identifies the time at which a maxima occurs of the cross-correlation function, thereby enabling derivation of the velocity of the scatterers.

The method further involves receiving a first, second, third, and fourth composite signals, where each of the composite signals includes a return signal and a reflected component.

摘要： The disclosed ultrasound imaging apparatus and method use a transducer array with a very large number of transducer elements or a transducer array with many more transducer elements than beamformer channels. The imaging apparatus includes a transmit array including a multiplicity of transducer elements allocated into several transmit sub-arrays, and a receive array including a multiplicity of transducer elements allocated into several receive sub-arrays. The apparatus also includes several intra-group transmit processors, connected to the transmit sub-arrays, constructed and arranged to generate a transmit acoustic beam directed into a region of interest, and several intra-group receive processors connected to the receive sub-arrays. Each intra-group receive processor is arranged to receive, from the transducer elements of the connected sub-array, transducer signals in response to echoes from the transmit acoustic beam. Each intra-group receive processor includes delay and summing elements constructed to delay and sum the received transducer signals. The apparatus also includes a receive beamformer including several processing channels connected to the intra-group receive processors, wherein each processing channel includes a beamformer delay constructed and arranged to synthesize receive beams from the echos by delaying signals received from the intra-group receive processor, and a beamformer summer (a summing junction) constructed and arranged to receive and sum signals from the processing channels. An image generator is constructed and arranged to form an image of the region of interest based on signals received from the receive beamformer. The apparatus is practical in size, cost and complexity and is sufficiently fast to provide two-dimensional or three-dimensional images of moving body organs.

摘要： In a phased array ultrasound imaging system, a high quality image is obtained by a combination of line splicing and parallel receive beamforming. Two transmit pulses, one focused in the near field and one focused in the far field, are transmitted sequentially at each steering angle. The transmitted ultrasound energy is preferably focused both in azimuth and in elevation. Ultrasound echos are simultaneously received along two receive scan lines spaced angularly on opposite sides of each transmit scan line. Signals received in response to the near field and far field transmit pulses are spliced together to provide signals that represent a high quality image throughout the region of interest. Image artifacts are reduced by blending the received signals near the splice between the near field and the far field, by dynamically steering the receive scan lines to reduce the effect of line warping, and by weighted averaging of adjacent scan lines.
