摘要： An ultrasound imaging system transmits two beams in succession in the same beam direction, the waveform of the second beam being a phase inverted form of the first waveform, and each waveform containing first and second major frequency components. Echoes are received from along the beam direction in response to each beam transmission, and are processed by additively and subtractively combining the two echo sequences on a common depth basis. The echo components resulting from this processing extend from high frequencies for good near field resolution to low frequencies for good depth penetration, and include fundamental, harmonic, and sum or difference frequency components. The linear and nonlinear echo signal components may be frequency compounded for speckle reduction.

摘要： A system and method for ultrasonic imaging utilizing multiple sets of transmit pulses differing in amplitude, frequency, phase, and/or pulse width. One embodiment has phase differences between the k transmit signal as 360 k degrees providing for constructive interference of the kth order harmonic pulse, while an amplitude modulation of each transmit profile is constant between sets. These sets of pulses are transmitted into media of interest and received echoes from these pulses are combined to form an averaged signal. The averaged pulses represent the net common mode signal received from each of the transmit sets. This combined signal set is used to reconstruct an ultrasound image based on broad beam reconstruction methodology.

摘要： An ultrasound diagnostic apparatus according to an embodiment includes an ultrasound probe and processing circuitry. The ultrasound probe sequentially executes sets of ultrasound transmission respectively along a plurality of scan lines, the sets each being composed only of transmission of first ultrasound having a first phase and transmission of second ultrasound having a second phase that is substantially 90 degrees different from the first phase. With respect to a first echo signal and a second echo signal that have been obtained via the ultrasound probe and correspond to the first ultrasound and the second ultrasound, respectively, the processing circuitry generates a subtraction signal by subtracting the second echo signal from the first echo signal. The processing circuitry generates an ultrasound image based on the subtraction signals generated for the scan lines.

摘要： The composite wave obtained by combining a fundamental wave having the center frequency f1 and a fundamental wave having the center frequency f2 is transmitted at least twice for each scanning line while performing phase modulation, and received an echo signal corresponding to each transmission for each scanning line. An echo signal in which harmonic components are canceled out, is extracted for each scanning line, by performing subtraction processing between echo signals which are obtained in this manner and respectively correspond to at least two transmissions. A signal strength difference (or a signal ratio if logarithmic compression is not performed) at each position on the scanned cross-section is calculated by using the f1 frequency component and f2 frequency component contained in the extracted echo signal. An attenuation image representing the signal strength difference at each position on the scanned cross-section is generated by using the calculated signal strength difference.
