Cancellous bone diagnosis system based on ultrasound backscattering signal parameters

Abstract

The invention belongs to the technical field of medical ultrasonography, and particularly relates to a cancellous bone diagnosis system based on ultrasound backscattering signal parameters. The system comprises an ultrasound backscattering signal acquisition module, a pretreatment module, a backscattering parameter calculation module and a cancellous bone state evaluation module. In the invention, an ultrasound transceiver probe is used to acquire ultrasound backscattering signals from the calcaneus of a human body; effective cancellous bone ultrasound backscattering signals are extracted; the calculation module is used to calculate four parameters, i.e. backscattering coefficient, apparent integration backscattering coefficient, spectral centroid shift and mean trabecular bone spacing; and finally, the health state of the cancellous bone is analyzed by comparing the four parameters with standard values stored in an internal standard database in the system. Compared with the traditional ultrasound transmission diagnosis system based on broadband ultrasound attenuation and ultrasound propagation velocity, the diagnosis system provided by the invention can obtain the complete information of the cancellous bone structure, thereby better detecting the health state of the cancellous bone of a human body.

Description

Technical field [0001] The invention belongs to the technical field of medical ultrasound, and specifically relates to a cancellous bone ultrasound diagnosis system. Background technique [0002] With the increasing aging of the population, osteoporosis has become one of the important issues affecting public health. When suffering from osteoporosis, it will cause the patient's bone mineral density to decrease and bone microstructure degradation. At present, the commonly used method for diagnosing osteoporosis is dual-energy X-ray measurement of bone density, but because it has ionizing radiation and the cost of the instrument is relatively expensive, it cannot be used as a daily detection method. Ultrasound diagnosis has the advantages of no ionizing radiation, convenience, fast speed, low price, etc., and has attracted more and more attention. [0003] At present, the commonly used method is the ultrasonic transmission method, which uses dual probes to obtain the ultrasonic tran...
