1. , for analyzing a ultrasonic diagnosis imaging system for blood flow, comprising:

  • Transducer array, it for transmitting and receiving ultrasonic signal on the volumetric region that there is blood flow;

    Be coupled to the B-mode processor of described transducer array, it is for generating the B-mode data of described volumetric region;

    Be coupled to the doppler processor of described transducer array, it is for generating the flow data of described volumetric region;

    The grayscale map that the reversion generating described B-mode data maps, wherein, described reversion mapping pair echoless inverse signal highlights;

    Be coupled to the volume renderer of described processor, it is for generating the volume drawing to the B-mode data through reversing and described flow data;

    Image merge processor, the flow data through volume drawing and the B-mode data set synthesis through reversion are contained the composograph of the feature of two kinds of data sets by it;

    AndBe coupled to described image merge processor, for showing the display of described composograph,Wherein, described image merge processor also comprises the comparator that the B-mode data through reversion and threshold value for making the pixel at Given Graph image position place compare, and, if the described B-mode data through reversion are on described threshold value, then to described pixel distribute described pixel through reversion B-mode data and described flow data value and, and wherein, the described flow data through volume drawing and the described B-mode data set through reversion are synthesized described composograph also based on the position in the gray level surface described by gray level and color image pixel and the described volume that is derived from of coloured surface.
