Embodiment Construction

[0017] An embodiment of the present invention provides a method for segmenting a three-dimensional target object in a medical ultrasound image.

[0018] In order to make the advantages of the technical solution of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] Such as figure 1 As shown, the segmentation method of the medical ultrasound image three-dimensional target object includes:

[0020] S101. Reorganize and rearrange the original scattered image data to obtain a regular body data set.

[0021] The original scattered image data is the original medical ultrasound image data containing the three-dimensional target object of the medical ultrasound image, and the spatial relative position of the original medical ultrasound image data is irregular, which is a scattered and irregular data set. By reorganizing and rearranging the original scattered image data, the ori...

Abstract

The embodiment of the invention discloses a segmentation method of a medical ultrasonic image three-dimensional target object, which is invented for solving the problems of low segmentation precision or nonideal time performance or low automation degree in the prior art. The segmentation method comprises that initial scattered medical ultrasonic image data including the medical ultrasonic image three-dimensional target object is restructured and a regular data set is obtained and segmented on the basis of a contour line. The concepts of keyframe and middle frame are led into the segmentation based on the contour line. A topological self-adaption deformation model and an interpolation based on shape are applied. The contour of the medical ultrasonic image three-dimensional target object can be obtained quickly and accurately. The invention is applicable to not only the segmentation of the medical ultrasonic image three-dimensional target object but also the segmentation of CT, MRI and other medical image order three-dimensional target objects.

Description

technical field [0001] The invention relates to the technical field of medical ultrasound image analysis and processing, in particular to a method for segmenting a three-dimensional target object of a medical ultrasound image. Background technique [0002] In the field of medical ultrasound image analysis and processing technology, the segmentation of three-dimensional target objects has important clinical application value. However, due to the constraints of the medical ultrasound imaging mechanism, the technical performance indicators such as signal-to-noise ratio, spatial resolution and contrast of the image are not ideal, which makes the segmentation of 3D target objects more difficult. The existing segmentation methods mainly include the method of manually marking the boundary, the method based on region growing and the method based on the traditional active contour model. [0003] Among them, the segmentation method of manually calibrated boundaries requires the opera...
