Automatic measuring method and device for volume change of skeletal muscle

Abstract

The invention provides an automatic measuring method and device for the volume change of a skeletal muscle. The device includes a data acquisition module, an image preprocessing module, a measurement module and a quantitative evaluation module, wherein the data acquisition module is combined with ultrasonic imaging equipment and collects a skeletal muscle cross-sectional ultrasound image, the image preprocessing module is used for reducing big speckle noise in the ultrasound image and enhancing the interest region contour of the image, the measurement module is used for extracting the interest region contour of the preprocessed ultrasound image, and the quantitative evaluation module is used for the quantitative analysis of the automatically extracted regional contour. The method and the device can automatically measure the volume change of the skeletal muscle, and have important clinical application value, for example, and a quantitative basis can be provided for the clinical diagnosis and rehabilitation evaluation of patients with sarcopenia.

Description

technical field [0001] The invention relates to a method and a device for measuring changes in skeletal muscle volume. Background technique [0002] Clinically, doctors use a tape measure to measure the limb circumference of patients with sarcopenia as a qualitative assessment method for skeletal muscle changes. Currently, the main quantitative diagnostic methods for sarcopenia include dual-energy x-ray absorptiometry (DXA), CT, MRI, and muscle strength measurement. [0003] The qualitative evaluation method of measuring the girth of the affected limb with a tape measure is highly subjective and imprecise. The dual-energy x-ray absorptiometry measurement system is complex and has radiation, and cannot accurately measure the cross-sectional area of ​​​​muscle and fat composition; CT and MRI are the measurement of muscle mass, muscle density and adipose tissue in vivo, and the assessment of muscle area. Currently the most accurate measurement method can be used as the gold s...

[0003] The qualitative assessment method of measuring the circumference of the affected limb with a tape measure is highly subjective and imprecise

The dual-energy x-ray absorptiometry measurement system is complex and has radiation, and cannot accurately measure the cross-sectional area of ​​​​muscle and fat composition; CT and MRI are the measurement of muscle mass, muscle density and adipose tissue in vivo, and the assessment of muscle area. Currently the most accurate measurement method can be used as the gold standard for diagnosis, but the inspection cost is expensive, the measurement analysis is complicated, and the radiation dose of CT is higher than that of dual-energy X-ray, so it is not suitable for frequent use, which limits its clinical application

The method of measuring muscle strength is imprecise and does not reveal morphological information about the muscle
