Problems solved by technology
[0007] There are several shortcomings in this traditional design method. First, the data obtained from the analog-to-digital converter needs to undergo a large amount of calculation processing to obtain the required useful signal, and the realization of these processing is to use a large number of dedicated digital At the expense of signal processing chips and other chips, this increases the cost of the product on the one hand, and on the other hand virtually increases the power consumption and volume of the product; another disadvantage is that the color ultrasonic imaging produced by this method System, its function is subject to the hardware circuit, if you want to add a new function, it is likely to redesign the circuit board, thus prolonging the development cycle of this function, but also increasing the development cost

Description
technical field [0001] The invention belongs to the technical field of color ultrasonic imaging, in particular to a data direct input color ultrasonic imaging system. Background technique [0002] Ultrasonic diagnostic technology is one of the three modern medical diagnostic technologies. It is a method and technology that uses ultrasonic methods to diagnose diseases by detecting and displaying the acoustic characteristics of human tissues and organs. The currently popular B-ultrasound and color Doppler ultrasound are all ultrasound diagnostic techniques. A general color ultrasonic diagnostic instrument includes main functions such as B-mode, Color-mode, M-mode, and Doppler-mode. [0003] B-mode, that is, B-type display mode, which uses brightness (Brightness) modulation to display the intensity of echo signals, and what it displays is a two-dimensional cross-sectional view of human organs. [0004] Color-mode, that is, the color flow mapping display method, is a method of...
