Embodiment Construction

[0043] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0044]Please refer to Figure 6 , the present invention provides a blood vessel modeling method, the method comprising the steps of: constructing a sphere, a column and a target volume density distribution; using the constructed sphere to generate a tubular target; using Gaussian noise to simulate the target background; using Markov statistics The model generates the texture of the background; the background and object are fused to form a simulated image using a proportional control method. Here the target can be a spherical or cylindrical target, a tubular target and an arterial tree target. The blood vessel modeling method uses the formed non-...

Abstract

The invention relates to a blood vessel modeling method, which comprises the following steps of: constructing density distribution of spherical bodies, cylindrical bodies and target bodies; using the constructed spherical bodies to generate a tubular target; using Gaussian noise to simulate a target background; using a Markov statistical model to generate textures of the background; and using a proportional control method to fuse the background with the target to form a simulated image. The blood vessel modeling method can provide a systematic simulation training dataset for mathematic split models of various medical images such as computerized tomography (CT) or magnetic resonance (MR) angiograms.

Description

【Technical field】 [0001] The invention belongs to the field of medical image processing, in particular to a blood vessel modeling method. 【Background technique】 [0002] Computer modeling and simulation is a very broad technical field. From the perspective of computer modeling and simulation of medical organs (such as the heart), it can be roughly divided into: shape modeling, structural data modeling, function and system Modeling and more. Among them, the modeling of structural data is of great significance to the analysis and research of medical images. Structural data modeling usually has the following approaches: (1) Manually or semi-automatically generate simulation data; (2) Obtain image data after imaging natural objects or specimens with similar shapes and adding some imaging agent; ( 3) Computer simulation data. Among them, the advantage of computer simulation data is that it can avoid the shortcomings of other methods that are difficult to control the proportion...
