Title:
SIMULATED AND MEASURED DATA-BASED MULTI-TARGET THREE-DIMENSIONAL ULTRASOUND IMAGE SEGMENTATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/023819
Kind Code:
A1
Abstract:
Simulated and measured data-based multi-target three-dimensional ultrasound image segmentation method, comprising the following steps: presetting a conventional acoustic parameter; collecting raw 3D data; employing an initial segmentation algorithm for segmenting the raw 3D data; substituting with the conventional acoustic parameter on the basis of probability to form a transitional image model comprising multiple complete target tissues; performing a simulation operation; transforming to produce simulated data; performing a comparison operation; adjusting corresponding magnitude of probability in each probability variable, and returning to the step of substituting with the conventional acoustic parameter. On the basis of the probability, the conventional acoustic parameter is substituted into an incomplete target tissue model, the simulation operation is then performed, the probability is adjusted on the basis of the degree of fit between the simulated data and the raw 3D data, this is performed repeatedly, corrections are made continually by iterative convergence until all incomplete target tissues are substituted by a certain normal tissue or lesion tissue, thus producing a complete image model, solving the shortcoming of a prior segmentation algorithm in which image segmentation is prevented by a shadow.
