Ultrasonic measurement analytical system for bone substance density

Abstract

The invention discloses an ultrasound bone density measuring and analyzing system. The system comprises an ultrasound parameter measuring apparatus, a communication interface and a human machine interaction device, wherein the ultrasound parameter measuring apparatus comprises transmitting unit consisting of a pulse generator, a high-voltage pulse excitation module and a transmitting probe, an ultrasound receiving unit consisting of a receiving probe, a simulation pretreatment module, a gain adjustable amplifier, a phrase comparator, a high-speed ADC and an asynchronous FIFO, and a central processor, a power supply control module and a structural body. the human machine interaction device controls the ultrasound parameter measuring apparatus through the communication interface to measure the width of a calcaneus of a detected person, the transmission speed of an ultrasound wave in the calcaneus, broadband ultrasonic attenuation to calculate the bone intensity indexes and the bone density, so a medical report can be made according to diagnostic standards of osteoporosis and a special data base can be built for long term use. The system adopts wet or dry coupling and other technologies to improve the precision and accuracy of measure and has the advantages of easy carrying, low cost, no damage caused by radiation and can be use in long term monitoring of bone condition of the detected person.

Description

[0001] Field [0002] The invention relates to ultrasonic sensor technology and information analysis technology and their application fields on medical devices, and particularly relates to an ultrasonic bone density measurement and analysis system for diagnosis and monitoring of osteoporosis. Background technique [0003] Osteoporosis is a systemic bone metabolism disorder that seriously endangers human health. It is estimated that there are currently about 200 million people suffering from osteoporosis in the world, and more than 90 million people in my country also suffer from osteoporosis, and these numbers are increasing. At the same time, osteoporosis is constantly losing bone mineral components and bone matrix in the same proportion, bone thinning, bone density and quality decline, bone strength decline, bone fragility increases and fracture risk increases (especially lumbar spine, hip Fractures of the hip and wrist) are characteristic, and bone loss can last for many years ...

AI Technical Summary

Problems solved by technology

The patent No. CN2891973 "ultrasonic bone density measurement and analysis device" discloses a device for measuring ultrasonic sound velocity SOS and ultrasonic amplitude attenuation to judge osteoporosis. There is no coupling method between the contact surface of the probe and the measured part to detect the interface acoustic wave. Decoupling is only an implementation on the hardware framework. The technical solution in the device lacks specific analysis and implementation, and the measurement accuracy and accuracy cannot be guaranteed.
