Embodiment 1

[0084] The correction method of the correction module 3 provided in the embodiment of the present invention includes:

[0085] (1) Through the detection circuit, the imitation blood is driven to move at a certain flow rate in the circulatory system through the circumferential pump, and the entire circulatory system squeezes the pipeline through the circumferential pump, so that the imitation blood starts from the liquid storage tank and passes through the circumferential pump, buffer tank, electronic The flow meter and phantom membrane are finally returned to the liquid storage tank.

[0086] (2) Feedback the collected flow rate information to the control system through the electronic flow meter of the flow meter, the system will compare the flow rate with the flow rate collected by the electronic flow meter according to the preset flow rate, and the control system will adjust the speed of the peripheral pump according to the comparison result to make the circulation The flow ...

[0090] Image optimization module 5 optimization methods provided by the present invention include:

[0091] 1) The image signal is obtained through the image optimization program, the R, G, and B data signals are obtained by analysis, and the corresponding grayscale images of the R, G, and B data signals are generated.

[0092] 2) After the error diffusion algorithm calculation and color quantization processing are performed on each grayscale image, the image data with reduced image signal bits is generated.

[0093] The calculation of the error diffusion algorithm provided by the present invention is to compare the pixel value of the current pixel point of the grayscale image with a threshold T to obtain a binary output. Then the input and output pixel error values ​​are diffused to the unprocessed area with a certain regularity. The error diffusion process of each pixel includes three steps: First, the pixel value of the original grayscale image at this pixel point is added...

Abstract

The invention belongs to the technical field of color ultrasound, and discloses a combined type detection and diagnosis color ultrasound system and detection method for ultrasonography department. Thedetection method comprises the steps of collecting ultrasound image data of a patient through an ultrasonic probe; rectifying color ultrasound diagnosis equipment through a rectifying procedure; performing color coding on blood flow signals through a coding algorithm, and overlaying the blood flow signals after being subjected to color coding on a two-dimensional image; performing optimization treatment on the collected ultrasound images through an optimizing procedure; extracting ultrasound image characteristic elements through an extraction procedure; performing diagnosis and analysis on the extracted characteristics through a diagnosis procedure; and displaying the ultrasound image data after being subjected to color coding through a displayer. Through a rectifying module, a lot of abuses of detecting equipment which is used at present can be effectively overcome, the detection time can be effectively shortened, the detection demands can be reduced, the detection items can be developed, and the mobility is improved. Besides, through an image optimization module, the signal digits of the ultrasound images can be reduced to be adapted to displaying demands of the displayer, the infidelity of image treatment is small, and ultrasound images excellent in quality can be obtained.

Description

technical field [0001] The invention belongs to the technical field of color ultrasound, and in particular relates to a combined detection and diagnosis color ultrasound system and detection method of the ultrasound department. Background technique [0002] Color ultrasound is usually composed of probes (phased array, linear array, convex array, mechanical sector scan, three-dimensional probe, endoscopic probe, etc.), ultrasonic transmitting / receiving circuits, signal processing and image display. Using ultrasonic Doppler technology and the principle of ultrasonic echo, it is a device for simultaneously collecting blood flow movement, tissue movement information and human organ tissue imaging. It is used for ultrasonic imaging, measurement and blood flow movement information collection for clinical ultrasonic diagnostic examination. The probe can pass through the esophagus, in the blood vessel, through the internal tissue of the human body during operation, and / or be used i...
