Abstract

The invention relates to a method for extracting multi-dimensional texture of nodi from medical images. The images are segmented by using a region growing method, content texture characteristic parameters of nodi are extracted by adopting a gray level co-occurrence matrix method, and edge texture characteristic parameters of the nodi are extracted by adopting a Curvelet conversion method. The method can enhance the edge information of the nodi and maintain the edge information thereof better so as to improve the accuracy of judging the properties of the nodi.

Description

Technical field:

[0001] The invention relates to a method for extracting multi-dimensional texture of nodules in medical images, in particular to a method for segmenting CT images of lung nodules and extracting texture features by combining region growth method, gray level co-occurrence matrix method and Curvelet transformation . Background technique:

[0002] In medical image processing containing nodules, it is of great significance to identify the nature of the nodules in the image. However, in the prior art, it is very difficult to determine the nature of nodules with a diameter below 3 cm. For example, in CT images containing pulmonary nodules, small pulmonary nodules (referring to lesions with a diameter of ≤3cm in the lung field) will appear in a variety of situations, including early lung malignant tumors (peripheral lung cancer), tuberculosis, and inflammatory pseudotumors Benign diseases such as hamartoma, pulmonary aspergillosis, etc. all showed small nodules on CT i...
