    Abstract: PROBLEM TO BE SOLVED: To clearly display thick blood vessels in capillary vessels by differentiating a coherent echo signal received from two pulse transmissions and detecting the differentiated signal and displaying it in an ultrasonic diagnostic apparatus for detecting coherent of an ultrasonic contrasting agent. SOLUTION: An ultrasonic probe 10 has an array 12 of an ultrasonic converter and an ultrasonic echo is transferred to a divided channel of a beam generator 16 through a transmitter/receiver 14 to form a sequence of a coherent echo signal in accordance with the depth of receiving in the body of a patient. After this echo signal is demodulated to a rectangular phase by means of an I/Q demodulator 18, it is filtered and detected and transferred to a scanning converter 40 through a B mode processor 37. I and Q signal components are transferred to a pulse-pulse differentiating circuit 24 and the differentiated signal is transferred to an event identifying tool 27 through an amplitude detector 20 and a micro-bubble destroying event is identified there and an image obtd. by an operation converter 40 is displayed on a displaying apparatus 50.

    Abstract: An ultrasonic diagnostic imaging system and method are provided for producing harmonic contrast images with harmonic components produced by the contrast agent with little interference from nonlinear tissue interaction. A method is described for developing predistorted ultrasonic transmit signals, the predistortion of which will be counteracted by the nonlinear effects of tissue and result in substantially linear waveforms at the location of the contrast agent. The echoes returned by the contrast agent will contain nonlinear components resulting from the interaction of a linear waveform with the agent, with reduced nonlinear components from nonlinear tissue effects.
