    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: SE MUESTRAN METODOS Y UN APARATO PARA LA DETECCION Y VISUALIZACION DE AGENTES DE CONTRASTE ULTRASONICO. SE PROPORCIONA UN APARATO ULTRASONICO PARA LA VISUALIZACION COHERENTE DE AGENTES DE CONTRASTE ULTRASONICO, Y PARA LA DETECCION DE AGENTES DE CONTRASTE ARMONICOS. EL APARATO DE ESTA INVENCION INCLUYE UNA VISUALIZACION DUAL PARA LA VISUALIZACION SIMULTANEA DE UNA IMAGEN EN TIEMPO REAL QUE PERMITE VER LA LOCALIZACION DEL AGENTE DE CONTRASTE Y LA IMAGEN DE CONTRASTE MOMENTANEA. LOS METODOS DE DETECCION DEL AGENTE DE CONTRASTE Y VISUALIZACION INCLUYEN LA MEDICION DE LAS TASAS CARACTERISTICAS DE PERFUSION, LA VISUALIZACION DE CONTRASTE EN MULTIPLES ZONAS, LA VISUALIZACION DEL CONTRASTE EN MULTIFRECUENCIA, LA VISUALIZACION DE LA PERFUSION DEL TEJIDO, LA ELIMINACION ARTIFICIAL DE LA VISUALIZACION DEL CONTRASTE PRF, Y LA ADQUISICION DE POLARIDAD ALTERNA DE EFECTOS DE CONTRASTE NO ALTERNOS.
