Ultrasonic diagnosis system of cancellous bone based on backscattered signal

Abstract

The invention belongs to the technical field of medical ultrasonic diagnosis, in particular to an ultrasonic diagnosis system for cancellous bone based on backscattering signals. The ultrasonic diagnostic system includes a power module, an ultrasonic signal transceiver, a communication interface, and a data processing and display system. The power supply module provides multiple power supplies for the system; the ultrasonic signal transceiver equipment includes: a central controller, a transceiver integrated probe, a pulse excitation unit, etc.; the data processing and display system controls the ultrasonic signal transceiver equipment to collect Ultrasonic backscatter signal, calculate ultrasonic backscatter coefficient, apparent integral backscatter coefficient, spectrum centroid offset and average trabecular spacing and other parameters; establish a database of corresponding parameters, and give a diagnosis according to the corresponding diagnostic criteria for osteoporosis Report. The invention uses the backscattering method to diagnose the cancellous bone, which can not only detect the amount of the cancellous bone, but also better reflect the microstructure of the cancellous bone. The invention is light and portable, has low production cost, simple operation and no radiation damage.

Description

technical field [0001] The invention belongs to the technical field of medical ultrasonic diagnosis, and in particular relates to an ultrasonic diagnosis system for cancellous bone based on backscattering signals. Background technique [0002] Osteoporosis, a skeletal disease caused by decreased bone strength, is a major health concern today. At present, about 200 million people in the world suffer from osteoporosis; there are now 143 million elderly people over 60 years old in China, and more than 100 million osteoporosis patients. Among the elderly over 60 years old, the incidence rate of osteoporosis is about 50%. Femur fracture is the most serious disaster of osteoporosis. The mortality rate after 6 months of fracture is 20%-24%, and 50% of the survivors cannot take care of themselves. Bone ultrasound diagnostic equipment can be used to frequently assess the bone condition. Therefore, the diagnosis of osteoporosis has been paid more and more attention by domestic and ...

Problems solved by technology

[0004] Currently the most commonly used diagnostic method is dual-energy X-ray (DXA) measurement of bone mineral density (BMD), but it cannot characterize cancellous bone microarchitecture; on the other hand , DXA is radioactive and expensive
