Abstract

The invention provides a pulmonary tuberculosis positioning and screening device and a computer device, and relates to the field of medical image processing. A method comprises: obtaining a to-be-processed orthotopic chest radiography image through the chest radiography image processing module; preprocessing the chest radiography image to obtain a target chest radiography image; extracting a lungfield foreground image from the target chest radiography image by adopting a lung field segmentation model through a lung field image extraction module; then, using a pulmonary tuberculosis segmentation screening model in a lung field distribution area of the lung field foreground image through a pulmonary tuberculosis screening module; positioning and segmenting a lesion area of the suspected pulmonary tuberculosis; calculating the diagnosis probability that the corresponding lesion area is screened as pulmonary tuberculosis; obtaining the pulmonary tuberculosis screening heat map and the pulmonary tuberculosis diagnosis probability, so that the pulmonary tuberculosis screening operation of the to-be-processed orthotopic chest radiography image is completed through the computer device, the pulmonary tuberculosis missing detection phenomenon in the pulmonary tuberculosis screening process is improved, the manual participation degree in the tuberculosis screening process is reduced, andthe pulmonary tuberculosis screening efficiency is improved.

Description

technical field [0001] The present application relates to the field of medical image processing, in particular, to a tuberculosis localization and screening device and computer equipment. Background technique [0002] In the medical field, tuberculosis is currently one of the infectious diseases with the highest fatality rate. At present, doctors use the naked eye to locate and identify tuberculosis-related lesions in the target orthotopic chest radiograph image to complete the tuberculosis screening operation. During this process, the screening scheme can usually only screen the obvious lesions in the frontal chest radiograph, but cannot screen the tiny lesions in the frontal chest radiograph, and tuberculosis is prone to missed detection. At the same time, the screening program has extremely high requirements on the medical quality of doctors, and the corresponding screening operations need to be completed manually by doctors, and the overall screening efficiency is not hi...
