摘要： A phased array ultrasonic imaging system including a transducer array for transmitting pulses of ultrasound energy in a transmitting mode and for receiving reflected ultrasound energy in a receiving mode, a transmit control circuit, coupled to and controlling the transducer array, for selecting an angle and a focus to steer a transmitted pulse of ultrasound energy in a desired direction in the transmitting mode, and a receive focusing circuit, coupled to the transducer array, for dynamically varying a receive steering angle and focus in real time during reception of ultrasound energy to focus the received ultrasound energy along at least one virtual scan line that is not required to pass through a center of mass of an applied apodization function. The at least one virtual scan line may originate at a virtual apex that is disposed at a location other than on a face of the transducer array.

摘要： A method of volume rendering includes obtaining data representative of a first composited plane of one or more anatomical structures and calculating data of a second composited plane as a function of a first composited plane. The data of the second composited plane is indicative of a measure of depth of the one or more anatomical structures along respective ray cast lines. The method also includes determining depth weighted color values between two different colorization palettes as a function of the measure of depths of the second composited plane. The determined depth weighted color values are applied to the first composited plane for producing a volume rendering image with depth weighted colorization.

摘要： This invention relates generally to an improved system and method that combines enhancing and mitigating techniques for speckle tracking, for obtaining a series of images of the movement of a target, such as tissue, over time. The method comprises steps of transmitting sound waves into the human body and outputting echoes of these sound waves; receiving and beamforming the echoes to produce scan line data; processing scan line data to display anatomical information using a method which reduces speckle; processing scan line data using a method or procedure which does not reduce speckle, and during one scan sequence, simultaneously acquiring the two scan line data, that data processed reducing speckle and that data processed without reducing speckle.

摘要： The present invention allows one to reconstruct high quality velocity waveforms using data collected at comparatively slow frame rates, such data would have otherwise resulted in non-diagnostic and non-clinically useful waveforms. The invention is directed to reconstructing a high quality “continuous” velocity waveform, and uses instantaneous measures of acceleration in addition to velocity to reconstruct such a waveform. By simultaneously detecting the velocity and acceleration of a fixed point in space, one can more faithfully reproduce the corresponding velocity waveform using significantly lower sample rates. If images are acquired, then the velocity sample rate corresponds to the image frame rate. Also, depending on the number of looks or scan lines contained in an ensemble, double interleaving of the raw data is used.

摘要： Ultrasound image data representative of three-dimensional volume segments of an image volume of interest is acquired in synchronism with corresponding cardiac cycles of a patient. The image data representative of the volume segments is combined to provide image data representative of a three-dimensional image of the image volume. The image data acquisition may be synchronized to a selected phase of the patient's cardiac cycle, so that the image represents the image volume at the selected phase. Image data for a three-dimensional volume segment may be acquired during each of the cardiac phases of a cardiac cycle.

摘要： In a technique for suppression of mirroring in a system which utilizes discrete Fourier transformation of an input signal, a correction apparatus adjusts the observed forward velocity spectrum by a first correction function and adjusts the observed reverse velocity spectrum by a second correction function to provide corrected velocity spectra. The first and second correction functions are representative of mismatches between the in-phase and quadrature channels of the signal processor. The correction functions are obtained during a calibration period in which calibration signals are applied to the signal processor. A first calibration signal contains frequencies of only forward velocities, and a second calibration signal conmtains frequencies representative of only reverse velocities. The correction functions are calculated from the spectra that were measured during calibration. In many cases, the first and second correction functions are the same.

摘要： This invention provides an ultrasonic transducer system which utilizes a reconfigurable delay line to perform a variety of processing functions. In particular, for a preferred embodiment, the delay line utilized to sum the outputs of transducer elements is reconfigurable to provide serial processing of image scan lines while providing parallel processing of Doppler color flow scan lines. More particularly, the echo signals generated in response to the packet of color flow lines utilized to generate color flow information are applied in a predetermined way to two separate portions of the delay line, the portions of the delay line having different delay profiles, the resulting outputs being focussed to slightly different points in the image and thus providing color flow packets for two separate points in response to the transmission of a single packet of color flow lines. This results in a substantial enhancement of the system frame rate.Other possible applications of the reconfigurable delay line in an ultrasonic scanning system are also discussed, and a packet serializer is disclosed which buffers, sequences, and preprocesses the received packet data.
