Description

technical field [0001] The invention relates to an ultrasonic imaging module and method, in particular to a color Doppler ultrasonic imaging module and method. Background technique [0002] Color Doppler is the use of autocorrelation technology for Doppler signal processing. The average velocity, variance and energy of blood flow obtained by autocorrelation technology are color-coded and superimposed on the two-dimensional grayscale image in real time to form a color Doppler image. Ultrasound blood flow images. [0003] In a color Doppler image, blood flow toward the probe is shown as a red signal, and blood flow away from the probe is shown as a blue signal. In addition to the above information, color Doppler images can also display information such as the speed of blood flow and reflect the nature of blood flow. [0004] Although the color Doppler technology plays an important role in the diagnosis of the patient's blood flow or moving tissue, there are still the followi...

Problems solved by technology

[0004] Although the color Doppler technology plays an important role in the diagnosis of the patient's blood flow or moving tissue, there are still the following deficiencies: First, in the color Doppler mode of the current ultrasonic diagnostic instrument, the doctor manually selects the corresponding Knob or button to determine whether to display color blood flow imaging, velocity variance imaging or energy imaging; secondly, in the color Doppler display, the displayed velocity range is determined by the pulse wave repetition frequency (PRF), while At the beginning of the examination, the speed range of the blood flow cannot be predicted accurately, and the doctor often sets a certain initial speed range based on experience, and then must be in the best state by continuously adjusting various parameter values ​​during the examination

In this way, on the one hand, the doctor has a large manual workload during the entire examination process. When there are a large number of patients diagnosed, it is inevitable that due to human factors, improper adjustment of the instrument may occur, so that some artifacts may appear during the application of color Doppler. , making it difficult to make correct diagnostic conclusions. On the other hand, there are many parameters that need to be adjusted manually, which is time-consuming and reduces the work efficiency of doctors to a certain extent.
