Abstract

The invention discloses a pulmonary nodule detection method and device. The method comprises the steps of inputting a to-be-detected image; outputting a pulmonary nodule candidate region through a preset candidate region network containing a three-dimensional convolutional feature pyramid; and eliminating the non-nodule region of the pulmonary nodule candidate region to obtain a pulmonary nodule detection result. According to the application, the technical problem that the pulmonary nodule detection effect is poor is solved. According to the method and the device, the candidate region relatedto the pulmonary nodules can be obtained under appropriate resolution, the non-pulmonary nodule region can be eliminated, and the training speed of a detection model can be remarkably increased by adopting a course learning strategy.

Description

technical field [0001] The present application relates to the fields of medical treatment and computer graphics, and specifically relates to a method and device for detecting pulmonary nodules. Background technique [0002] Pulmonary nodules are one of the most important signs of lung cancer. Computed Tomography (abbreviation: CT) is the most effective way to detect pulmonary nodules. Therefore, a lung nodule detection algorithm based on computerized tomography is studied. Very necessary. [0003] The inventors found that the current pulmonary nodule detection method uses a deep convolutional neural network to extract discriminative features, but cannot handle the actual detection scenarios of nodules of different sizes well. [0004] Aiming at the problem of poor detection effect of pulmonary nodules in related technologies, no effective solution has been proposed so far. Contents of the invention [0005] The main purpose of the present application is to provide a meth...
