Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] like figure 1 As shown, the backscattered ultrasonic bone diagnosis system based on the Android platform of the present invention includes: a hardware layer 1, a driver layer, an Android system layer 3, and an application layer 4.

[0025] The hardware layer 1 is located at the bottom layer, and its module block diagram is as follows figure 2 shown. It includes an ARM processor 11, an LCD display 12, an FPGA chip 13, a high-voltage pulse transmitting circuit 14, a high-voltage isolation receiving and analog-to-digital conversion circuit 15, and an ultrasonic transducer 16. In this embodiment, the ARM processor 11 and the FPGA chip 13 communicate through the SPI bus, and other high-speed parallel buses or serial buses may also be used. The ARM processor 11 is connected to a 10-inch LCD display 12 through a video bus. The FPGA chip 13 controls...

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a back-scattering ultrasonic bone quality diagnosis system based on an Android platform. The system is composed of a hardware layer, a driving layer, an Android system layer and an application layer; the architecture combining ARM, an FPGA and an analog circuit is adopted in hardware of the bottom layer, and an Android system runs on an ARM processor and controls the hardware of the bottom layer through the driving layer; the application layer runs on the Android system to achieve all processes and functions of back-scattering ultrasonic bone quality diagnosis; the application layer comprises an ultrasonic measurement module, a parameter setting module, a man-machine interaction module, an algorithm processing module and a database access module, wherein the algorithm processing module obtains parameters such as the back-scattering coefficient (BSC), the apparent integral back-scattering coefficient (AIB) and back-scattering spectral centroid skewing (SCS) through calculation of a signal processing algorithm and evaluates the bone quality by synthesizing the parameters; multi-task scheduling processing is achieved through the Android operation system, and therefore the reliability and the real-time response performance of the system are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a bone diagnosis system based on ultrasonic backscattering. Background technique [0002] Currently widely used bone diagnosis methods are mainly based on X-ray technology, including dual-energy X-ray (DXA) and quantitative CT and other technologies. However, radioactive bone density measurement technology has ionizing radiation on the human body, and the equipment is huge and expensive. Due to the advantages of non-destructive, non-ionizing radiation, low cost and portability, ultrasonic methods are considered to have great application prospects in bone quality evaluation. [0003] Ultrasonic bone diagnosis methods are mainly divided into ultrasonic transmission method and backscatter method. Ultrasonic transmission method was developed earlier and has been clinically applied. Ultrasound transmission generally evaluates the bone condition by measuring parameters s...
