A method with its corresponding device to produce an image of an area under investigation

摘要

Method and apparatus for the production of an image of an area under investigation.The Method comprises the operations of generating a First Output Signal representing the amplitude information of the signal using an echo amplitude DEMODULATION of a Signal derived from the echo Signal; generating a Second signal that represents the information of frequency or FAS And The Echo Signal through a DEMODULATION Frequency or phase of the signal from the signal andCo; and combining the first and second output signals to generate a signal that can be displayed by means of Image Display to produce the image area. Application of Medical Ultrasonic diagnosis.
