Abstract

The invention provides a pulmonary nodule detection method and system, and belongs to the technical field of image recognition, and the method comprises the steps of obtaining a to-be-detected lung CT scanning image; performing resampling and normalization on the obtained lung CT scanning image to be detected, and performing expansion operation processing on the mask; processing the processed to-be-detected lung CT scanning image by using the trained detection model to obtain a detection result, wherein the detection result comprises whether the pulmonary nodule exists in the to-be-detected lung CT scanning image and the calibration position and the area size of the pulmonary nodule, the trained detection model is obtained through training by using a training set, the training set comprises a plurality of lung CT scanning images and labels for labeling positions and areas of pulmonary nodules in the images. According to the invention, accurate detection of the pulmonary nodule area is realized, the detection efficiency is improved, the detection quality is ensured, and the stability and efficiency of assisting doctors in disease diagnosis are improved.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a method and system for detecting pulmonary nodules. Background technique [0002] Early detection and treatment of potential small lesions of lung cancer play an important role in reducing the morbidity and mortality of lung cancer patients. At present, low-dose computed tomography (LDCT) is mainly used for lung nodule screening, and enhanced CT images are the direct basis for doctors to diagnose lung cancer through direct observation. The type, structure, size, and location of pulmonary nodules in CT images are different. It is difficult for doctors to process and analyze image data in screening slices, and they are more easily affected by the subjectivity of doctors. At the same time, the number of enhanced CT images is also increasing. work poses great challenges. [0003] Obviously, it is extremely difficult to observe and find tiny pulmonary nodules in slices on...
