Abstract

The embodiments of the invention provide a chromaticblood flow imaging noise suppression method and device.Thechromaticblood flow imaging noise suppression method comprises the steps thatanultrasonicecho signal is received, and a complex signal and a first energy component are generated according to theultrasonic echo signal; the complex signal is subjected to a two-way treatment, a first image comprising a first velocity image component and a first variance image component and a second image comprising a second velocity image component and a mode image component are obtained respectively, the first image and the second image are marked respectively to obtain a first marked image and a second marked image, and the first marked image and the second marked image are treated according to a preset policy to obtain a binary image; a third image is generated according to the first energy component and the first image; the third image is subjected to mask calculation according to the binaryimage to obtain achromaticblood flow image. According to the chromaticblood flow imaging noise suppression method and device, blood flow interference noise can beeffectively suppressed, and thus accuracy of chromaticblood flow imaging is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of blood flow imaging, and in particular, to a method and device for suppressing noise in color blood flow imaging. Background technique [0002] Color blood flow imaging in ultrasonic diagnostic equipment is obtained by detecting the Doppler frequency shift of blood flow. In blood flow detection, the ultrasonic equipment transmits ultrasonic waves to the subject through the probe, then receives the echo of the subject, and performs quadrature demodulation, low-pass filtering, wall filtering, and autocorrelation estimation on the received radio frequency echo data And so on, the speed, variance and energy of the detected part are generated. Pure color blood flow images can display blood flow at all flow velocities and energies without any interference noise, including tissue movement interference, electronic noise interference, and probe movement interference. [0003] In the prior ar...
