Bone detection device and bone detection method

Abstract

The invention provides a bone detection device and a bone detection method. The bone detection device includes a transmitter, a receiver and a processor, wherein the transmitter is used for transmitting ultrasonic signals to a bone area; the receiver is used for receiving ultrasonic signals propagated from the bone area; the processor is used for calculating the included angle Phi between the detection surface, associated with the transmitter and the receiver, and the bone surface of the bone area at least based on the propagation time of the ultrasonic signals from the transmitter to the receiver. According to the bone detection device and bone detection method, provided by the invention, the included angle between the detection surface and the bone surface can be calculated and provided in a real-time manner, so that an operator of the bone detection device can know the included angle timely and adjust the detection surface according to the included angle, and the improvement of the efficiency and correctness of the bone mineral density detection is facilitated.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a bone detection device and a bone detection method. Background technique [0002] Bone strength is an important indicator for evaluating human health status. Clinically, bone mineral density (abbreviated as "bone density") is usually used to characterize the health of bones. Ultrasonic bone density detection technology has attracted widespread attention due to its non-radiation and sensitivity to diagnosis of fractures. Studies have shown that the propagation speed of ultrasonic waves in bones is positively correlated with bone density, and the bone density can be known by detecting the propagation speed of ultrasonic waves in bones. [0003] For bone density detection based on ultrasonic axial conduction technology, long bones such as radius and tibia are usually selected as detection objects. A bone density probe generally includes multiple ultrasonic transmitters (referred to...

AI Technical Summary

Problems solved by technology

However, in the actual detection process, due to the cover of soft tissue, the operator cannot intuitively understand the angle between the probe surface and the bone surface, so the process of adjusting the angle of the probe surface will be time-consuming

Moreover, because the soft tissue itself is relatively soft, it is difficult to maintain a parallel state for a long time, which will also lead to a longer detection time
