    Abstract: An ultrasound imaging system includes an ultrasound probe having an array of transducer elements divided into a plurality of contiguous transmit sub-apertures. A plurality of transmitters coupled to the sub-apertures of the ultrasound transducer apply respective transmit signals to the sub-apertures at different frequencies and with delays that cause respective transmit beams emanating from the sub-apertures to overlap each other in a region of interest. A multiline beamformer coupled to the transducer elements processes signals corresponding to ultrasound echoes to output image signals. A processor receives the image signals from the multiline beamformer and outputs image data corresponding to the image signals. The image data are processed by an image processor to output corresponding display signals that are applied to a display.

    Abstract: An ultrasonic diagnostic imaging system and method are described for performing nonlinear echo signal imaging with harmonic and intermodulation product (sum or difference frequency) components. Both the harmonic and the intermodulation products are produced by nonlinear effects of tissue or contrast agents and both are advantageously separated from the fundamental transmit components of the echo signals by pulse inversion processing. The use of both nonlinear components can improve the signal to noise ratio of the ultrasonic images, and the two types of components can be blended or used in different regions of an image to offset the effects of depth dependent attenuation.

    Abstract: When an ultrasound transducer is driven by a signal that contains a relatively wide range of frequencies, the frequency-dependent attenuation characteristics of the subject being imaged can be relied on to simultaneously provide, using only a single pulse per line of the image, (a) a return from the deeper portions of the image that is dominated by lower frequencies and (b) a return from the shallower portions of the image that is dominated by higher frequencies. These returns are processed into an image with higher resolution in the shallower parts, and lower resolution with adequate SNR in the deeper parts.
