Abstract

The invention discloses a coding device and a coding method of a color doppler ultrasonic diagnostic apparatus; wherein, the coding device consists of a variable selection module, a double-threshold control module and a coding module; the variable selection module and the double-threshold control module are respectively connected with the coding module; the variable selection module is used for determining corresponding imaging variables according to a selected color blood flow imaging mode and outputs the imaging variables to the coding module, the double-threshold control module is used for setting a velocity threshold and a gray threshold and for comparing the absolute value of input average velocity data as well as two-dimensional gray value data with the velocity threshold and the gray threshold respectively to form a color code index which is output to the coding module, and the coding module is used for color-coding the imaging variables according to the color code index or performing gray code to the two-dimensional gray value data.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a coding device and method for a color Doppler ultrasonic diagnostic instrument. Background technique [0002] The color Doppler ultrasonic diagnostic instrument uses the Doppler principle to obtain the average velocity, variance and energy of the blood flow in the color blood flow imaging area, and obtains a two-dimensional color image representing the blood flow after color coding. The process of color Doppler imaging is: the excitation is emitted to make the probe emit pulsed sound waves, and the beam emitted by the probe is reflected by the inspected part to produce a frequency shift and then received by the probe. After receiving amplification and beam synthesis, the echo signal is orthogonally resolved. The demodulated signal is divided into two channels, one is B-mode imaging processing to obtain a two-dimensional grayscale image, and the other is wall filtering ...
