Various methods and systems for color flow ultrasound imaging of arteries and veins are provided. In one embodiment, a method comprises acquiring a color flow image, automatically identifying an artery and a vein within the color flow image, and adjusting at least one imaging parameter responsive to the automatic identification of the artery and the vein. In this way, flow velocities and volume flow in arteries and veins may be measured with minimal adjustments or input by a user, thereby increasing the accuracy and consistency of measurements and reducing the time needed for blood flow measurements.

To prevent or reduce the blurring of the edge of a blood flow in the display of flow velocity data.SOLUTION: The processor removes noise from the power data 110 extracted from the color flow data 100 (block 14), and obtains a gradient at each pixel as the blood flow form information 114 from the power data 112 after noise removal (block 16). Further, the processor performs noise removal on the flow velocity data 120 extracted from the color flow data 100 using the blood flow form information 114 (block 20). In this denoising, the processor uses, for example, a denoising filter that considers, for each pixel, only a pixel group along a direction perpendicular to the gradient at the pixel.SELECTED DRAWING: Figure 2

Blurring of blood flow flanks when displaying flow velocity data can be prevented or reduced. A processor removes noise from power data extracted from color flow data and obtains a gradient at each pixel as blood flow morphology information from the power data after noise removal. Additionally, the processor performs noise removal on flow velocity data extracted from the color flow data using the blood flow morphology information. For example, in noise removal, the processor uses a noise removal filter for each pixel that considers only a group of pixels along a direction perpendicular to the gradient at each pixel.

The invention provides an ultrasound image processing apparatus, a computer program product, and a recording medium. The present invention addresses the problem of preventing or reducing blurring of a blood flow edge in display of flow rate data. A processor removes noise from power data (110) extracted from color stream data (100) (functional module (14)), and finds a gradient in each pixel from the power data (112) after noise removal as blood flow pattern information (114) (functional module (16)). And, the processor uses the blood flow morphology information (114) to noise remove flow rate data (120) extracted from the color flow data (100) (functional module (20)). In the noise removal, the processor uses, for example, a noise removal filter that takes into account only a group of pixels along a direction perpendicular to a gradient in the pixel for each pixel.

The present application relates to a kind of acute leukemia (ALL) high flux flow detection kit, belong to leukemia detection field, the present application is based on the original 8 color flow to increase 16 kinds of ALL cell antigen, can realize the simultaneous detection of 24 kinds of antigens in the same cell, not only greatly improve the detection precision of micro residual lesion (MRD), and by being divided into 12 development stages to ALL cell, can more accurately identify immunotyping when first diagnosis, and immunophenotypic aberration after bone marrow transplantation and after CAR-T cell therapy, this has very important guiding significance to the evaluation of patient treatment effect and the adjustment of treatment scheme.

A processor removes noise from power data extracted from color flow data, and obtains a gradient at each pixel as blood flow morphology information from the power data after the noise is removed. In addition, the processor performs noise removal on flow velocity data extracted from the color flow data using the blood flow morphology information. In the noise removal, the processor uses, for example, for each pixel, a noise removal filter that considers only a pixel group along a direction perpendicular to the gradient at each pixel.
