Problems solved by technology

[0004] Bone density testing is used to understand the patient's bone density status and check whether the patient is suffering from osteoporosis. The detection rays cannot penetrate the inspector's body very well, and the obtained detection results are blurred, and the results cannot be clearly analyzed, which is not conducive to the doctor's treatment of the patient's illness

Abstract

The invention discloses an ultrasonic-based tibial bone mineral density detection system and method. The system comprises an ultrasonic transmission driving circuit, an ultrasonic probe, a receiving circuit and a data acquisition card, wherein the ultrasonic transmission driving circuit transmits a control signal to drive the ultrasonic probe to work; the ultrasonic probe generates pulsed ultrasonic waves which are coupled and enter the cortical layer of the middle section of a tibia; the ultrasonic reflection signal of the coupled pulsed ultrasonic waves is received by the ultrasonic receiving probe and converted into a weak electric pulse signal by a piezoelectric wafer; then the weak electric pulse signal is amplified by the receiving circuit and then filtered and transmitted to an oscilloscope; processing is performed on the weak electric pulse signal so as to obtain a usable electrical signal; and the data acquisition card acquires the usable electrical signal to a PC for data processing. In virtue of an ultrasonic technology, the data acquisition card acquires date according to the actual need for an ultrasonic propagation velocity in detection of the cortical bone of the tibia, the time value of the ultrasonic propagation in the tibia is extracted based on the acquired signal, and the value of bone mineral density is calculated according to a formula. The entire operation system is simple in structure; and the calculation method is easy and has high accuracy.

Description

technical field [0001] The invention relates to the technical field of bone density detection, in particular to an ultrasound-based tibial bone density detection system and method. Background technique [0002] The human skeleton is composed of many bones, and the functions of each bone are different. Whether it will affect the hardness of each bone, that is, bone density; and whether the bone density is normal or not can also be a sign of whether the bone is healthy, so bone density Measurement is even more important. Osteoporosis is a disease of bone metabolism. When the bone loss is too fast or the synthesis is abnormal, the bone will become loose and fractures will occur easily. [0003] The tibia is one of the two bones of the lower leg. It is located on the inner side of the lower leg and plays an important role in supporting body weight. It can be divided into one body and two ends. The upper end expands to form the medial and lateral bones, and forms the knee joint...
