Problems solved by technology

However, this algorithm has the following disadvantages: (1) Different objects have different data characteristics, so that different 3D reconstruction methods can be used correspondingly, but this article does not give how to choose different methods according to different objects. It is very important in 3D rendering; (2) This article uses a single rendering channel, which requires a lot of calculation when rendering 3D objects, and is not suitable for use on ordinary personal computers; (3) The 3D images drawn by this algorithm The object is a unified whole, and the internal structure of the object cannot be observed intuitively

Embodiment Construction

[0024] The following examples are provided in conjunction with the specific content of the method of the present invention:

[0025] The two-dimensional image sequence of human organs collected by the nuclear magnetic resonance equipment is a two-dimensional tomographic image sequence that satisfies various complex features. In practical application, the doctor judges the position of various tissues and organs of the human body by observing the characteristics of each image in the sequence, focusing on determining the position of the diseased tissue, so as to formulate a plan for radiation therapy and surgery. The present invention can be applied to such occasions.

[0026] The two-dimensional image sequence used in this example is the leg of a 17-year-old boy (including osteosarcoma) collected by a certain hospital using a 1.5T nuclear magnetic resonance imaging device (Eclipse 1.5T, Marconi Medical Systems, Inc,). ) of two-dimensional image sequences.

Abstract

The invention is a three-dimension reconstruction method for two-dimension image series, which is applied to image processing technology field. The steps are: carries on partition to two-dimension image series, cuts out the interest parts in image series, and the partition image series is constructed into a three-dimension data, nd they are classified according to the character of object, constructs the object table; according to the processed image series, creates the total painting model and local painting model of the three-dimension display; carries on three-dimension reconstruction to the two-dimension image series according to the models, and carries on global painting model to each object in the table; paints the three-dimension object with computer painting meanings and displays it on the computer screen; places two cutting planes, free shift and rotating cut planes in the three-dimension object, realizes the partition in any direction to the three-dimension object.

Description

technical field [0001] The present invention relates to an image reconstruction method used in the technical field of image processing, in particular to a three-dimensional reconstruction method of a two-dimensional image sequence. Background technique [0002] A two-dimensional image sequence refers to a series of two-dimensional images representing cross-sectional information at different positions of an object. Their size, resolution and color information are the same, and the positions represented by the images are spatially adjacent, so the two-dimensional image sequence It has some three-dimensional features of the object, such as the tomographic image sequence of human organs collected by nuclear magnetic resonance equipment. The three-dimensional reconstruction of the two-dimensional image sequence is to construct the three-dimensional data of the tissue to be constructed after segmentation and extraction according to the input tomographic image sequence. This can r...
