Embodiment Construction

[0026] The following describes the images in the accompanying drawings in conjunction with specific processing steps:

[0027] 1. The overall implementation process of the processing method of the present invention

[0028] See figure 1 , the overall implementation process of the image processing method of the present invention to automatically measure the thickness of the nape of the fetus from the ultrasound image is:

[0029] Step 1: Input of images collected by the ultrasonic instrument and import of shooting parameters. The format of the input image is a common raster image, such as jpg, bmp format, and the source of the image is collected by a medical ultrasound instrument. Get the scale, brightness, and contrast parameters of the original image. Some medical ultrasound instruments can provide certain parameters (such as scale), which can be directly imported into the system of this method.

[0030] Step 2: Evaluation of the quality of ultrasound images of fetal nape...

Abstract

The invention provides an image processing method for automatically measuring the thickness of a fetal nuchal translucency from an ultrasonic image. The image processing method comprises the following steps that an ultrasonic instrument collects the input of an image and the importing of shooting parameters; quality analysis of an ultrasonic image to be detected of the fetal nuchal translucency based on Gabor feature matching is carried out; the ultrasonic image which accords with a measurement condition is screened according to a Gabor feature matching degree of the images in an image region and a training set; with regard to the ultrasonic image which accords with the measurement requirements, the position of the NT in the ultrasonic image is detected; a partial image of a clear NT line can be measured by a final output of the step through gradually-iterative threshold segmentation, canny operator edge detection and hough transform line detection; an NT target in the ultrasonic image can be measured; a K-MEANS method is used for classifying lines of NT target positions and upper and lower two clusters of line sections are aggregated to find out two measurement lines of the NT positions, and measuring a maximum pixel distance between the two lines; and the pixel distance of the NT is converted into a real length value according to a measuring scale of the shooting parameters.

Description

technical field [0001] The invention relates to digital image target measurement technology, in particular to automatic analysis of obstetric ultrasound images and image target measurement technology. Background technique [0002] Ultrasound imaging plays an important role in medical imaging technology. The physical characteristics of ultrasound imaging hardware lead to a low signal-to-noise ratio of ultrasound images, which adversely affects the quantitative analysis of images. At present, the feature extraction and analysis methods for ultrasound images still lag behind the development of ultrasound imaging technology itself. It is of great significance to introduce automated target measurement and analysis methods in ultrasound image analysis. [0003] Ultrasound image analysis in obstetrics is an important means to evaluate the growth and development of fetus in uterus, which has the advantages of non-destructive, cheap and real-time. In the analysis of obstetric ultr...
