Abstract

The invention provides a lung detection method and device based on PET / CT image features. The method comprises the steps that the local image of a region corresponding to a lesion is acquired from a PET / CT image library as a training image; the PET / CT image library comprises the lung lesion images of multiple types of lesions; the training image is transformed and filtered to acquire a processed training image; the feature information of the processed training image is extracted, wherein the feature information comprises one or combination of texture feature information and color feature information; a lesion detection model is established according to the feature information; and a lung image to be detected is detected based on the lesion detection model to determine the type of the lesion in the lung image to be detected. An image processing technology is used to carry out lesion analysis and identification on a PET / CT image, which improves the accuracy and sensitivity of lesion identification.

Description

technical field [0001] The present invention relates to the technical field of medical digital image processing, in particular to a method and device for lung detection based on PET / CT image features. Background technique [0002] Lung cancer is one of the deadliest cancers worldwide. PET / CT (positron emission tomography / computer tomography, positron emission tomography / computer tomography), as a non-innovative imaging diagnostic technology, has made great progress in the application of lung cancer diagnosis and preoperative staging in recent years . Compared with traditional CT (computertomography, computerized tomography), MRI (Magnetic Resonance Imaging, magnetic resonance imaging) or pure PET (positron emission tomography, positron emission tomography), the advantages of PET / CT technology are very obvious. [0003] In terms of detecting and locating tumor tissue using PET / CT images, there have been some techniques that apply threshold judgment and SUV value comparison...
