Nuclear medicine pulmonary perfusion imaging quantitative analysis method and analysis equipment, and storage medium

Abstract

The invention relates to the measurement technology of pulmonary volume and pulmonary perfusion volume, in particular to a nuclear medicine pulmonary perfusion imaging quantitative analysis method andanalysis equipment, and a storage medium. The analysis method comprises the following steps of: preprocessing a patient examination image, and classifying images into dissection images and perfusionimages; and according to different types of images, selecting a corresponding way to process the examination image, obtaining dissected pulmonary net volume and perfused lung net volume, and carryingout calculation to obtain a perfusion effective volume ratio. The analysis method can automatically identify a pulmonary area in the image and can accurately carry out pulmonary perfusion imaging quantitative analysis.

Description

technical field [0001] The invention relates to the measurement technology of lung capacity and lung perfusion capacity, in particular to a quantitative analysis method, analysis equipment and storage medium of nuclear medicine lung perfusion imaging. Background technique [0002] Nuclear medicine lung perfusion imaging has important clinical significance for the correct diagnosis and curative effect evaluation of lung diseases by judging the status of pulmonary blood perfusion. At present, the image analysis of lung perfusion imaging is mainly through visual observation, which is intuitive and simple, but the evaluation is relatively subjective, takes a long time, and the consistency between observers may be mediocre. [0003] In recent years, there has been a semi-automatic image analysis technology to obtain perfusion volume. This technology manually frames images and calculates high-brightness pixels based on images within the frame range; due to the failure to automatic...

Problems solved by technology

At present, the image analysis of lung perfusion imaging is mainly observed by naked eyes, which is intuitive and simple, but the evaluation is relatively subjective, takes a long time, and the consistency between observers may be mediocre

[0003] In recent years, there has been a semi-automatic image analysis technology to obtain perfusion volume. This technology manually frames images and calculates high-brightness pixels based on images within the frame range; due to the failure to automatically frame images and calculate them, and the lack of contrast functions , so that imaging doctors still need to spend a lot of time on operations and calculations to obtain the examination result data

The semi-automatic analysis technology is not yet popular, and the image analysis of lung perfusion imaging is currently mainly observed by the naked eye.
