1. a ultrasonic imaging apparatus, is characterized in that, possesses:

  • Ultrasonic transmission/reception mechanism, it is sent ultrasound wave and receives ultrasound wave tested having a medical check-up by ultrasound probe, and described ultrasound probe possesses;

    relative to pressing contact surface between vertically disposed and described tested the having a medical check-up of direction and by making described contact surface move in the described direction of pressing the compression mechanism of using the pressure stipulated to oppress described tested imaging object position of having a medical check-up;

    Ultrasonic transmission/reception controlling organization, it is controlled described hyperacoustic transmission and reception;

    Tomoscan mechanism, it adopts from the reflection echo signal of described ultrasonic transmission/reception mechanism output, and the cycle in accordance with regulations repeats to obtain and comprises the ultrasound wave reception signal frame data of motor tissue interior tested having a medical check-up in;

    Signal processing mechanism, its carry out by described tomoscan mechanism, obtain by a plurality of ultrasound wave of seasonal effect in time series, receive the signal processing of signal frame data;

    Black and white monochrome information mapping device, it will be transformed into black and white faultage image data by seasonal effect in time series tomography frame data from described signal processing mechanism;

    Ultrasound wave receives signal frame data selection mechanism, and it is from receiving signal frame data set by a plurality of ultrasound wave of seasonal effect in time series of obtaining by described tomoscan mechanism, and the ultrasound wave that is selected to the object of displacement measurement receives the group of signal frame data;

    Displacement measurement mechanism, its group based on receive signal frame data selection mechanism selected ultrasound wave reception signal frame data by described ultrasound wave, measures the amount of movement of each point on faultage image or displacement;

    Pressure measxurement mechanism, its body intracavity pressure to described tested imaging object position of having a medical check-up is measured or is inferred;

    Distortion and elastic modelling quantity arithmetical organ, it is based on by the measured described displacement of described displacement measurement mechanism and by the measured described body intracavity pressure of described pressure measxurement mechanism, distortion and the elastic modelling quantity of each point generate the first elasticity frame data on faultage image described in computing;

    Elastic data processing mechanism, it carries out signal processing and generates the second elasticity frame data described the first elasticity frame data that generated by described distortion and elastic modelling quantity arithmetical organ;

    Hue information mapping device or black and white monochrome information mapping device, described the second elasticity frame data that its input generates by described elastic data processing mechanism are also given hue information or black and white monochrome information;

    Switch adding mechanism, it is by the black and white faultage image data from described black and white monochrome information mapping device, be added or send separately with color elastic view data from hue information mapping device or from the black and white elastic image data of black and white monochrome information mapping device;

    WithImage indication mechanism, it shows the view data of switching adding mechanism from this,According to described ultrasound wave, receive the cycle information of signal frame data, control the pressing action of described compression mechanism.
