The invention relates to a three-dimensional ultrasonography-based early liver cancer diseased tissue target detection method. The method comprises the following steps of: (1) scanning a three-dimensional ultrasonic reconstruction C surface by using a free arm; (2) scanning a target by a coordinate displacement method or a sector scanning method, and observing the C surface of an image in a minimum three-dimensional reconstruction mode; (3) amplifying and observing the shape, brightness, distribution condition and internal structure of an actual image of the target; (4) effectively reflecting the valuable ultrasonographic information in a three-dimensional mode; and (5) enabling the display precision of the image of the target to reach 0.1 millimeter-scale level sampling thickness. The three-dimensional ultrasonography-based early liver cancer diseased tissue target detection method has the advantages that: the imaging mode breaks through the limit of the action of an ultrasonic physical principle, a diseased tissue of which the minimum size is about 0.1mm can be observed, and an effect similar to a microscopic observation effect is achieved; a brand new image structure is generated to ensure that the information content of an ultrasonic image is greatly enriched and the objectivity and accuracy of image analysis are obviously improved; and the method lays a novel important basis for early diagnosis and treatment of various liver diseases.
