Along with the raising of people's living standard, people more and more pay attention to the health problem of self, and various medical monitoring equipment emerge in an endless stream.Fracture had ever-increasing trend in recent years, when fracture deal with improperly or the untimely consequence of bringing more serious, especially in old man and these weak populations of child, treatment of fractures causes soft tissue infection, arthritis probably if deal with improperly, severe patient even cacomelia may occur is so become very important to the monitoring of fracture.
The fracture monitoring mainly is the gap size that detects the skeleton place, near situation and the body temperature value of the soft tissue of skeleton, learns the healing state of fracture with this.At present X-rays and the CT of adopting come the situation of skeleton is observed and diagnosed more, and X-ray can obtain the perspective view of skeleton, but it is relatively poor to the resolving power of soft tissue, and human body is had radiation injury; The diagnosis effect of the soft tissue of CT is better, but expense is expensive and equally human body is had radiation injury.
And for the inspection of internal organs, many technology with ultra sonic imaging now are as widely used B ultrasonic.This is because ultrasonicly have a very high soft tissue resolving power.At present, ultra sonic imaging can be obtained the image space resolving power that is better than 1mm at the detection depth bounds of nearly 20cm.But detecting for skeleton, use the method for ultra sonic imaging improper, because ultrasonicly can't penetrate skeleton as X-ray, is not very desirable to the imaging effect of skeleton.Yet the characteristic that but can utilize ultrasonic reflection detects the situation of skeleton.When ultrasound wave to continue extremely short time transmit burst in the human body time because ultrasound wave can't penetrate skeleton, so almost all reflect at skeleton place ultrasound wave, can detect the gap size at skeleton place according to echo.Equally, when the irradiation soft tissue, each layer of soft tissue comprises skin, muscle, blood vessel, and ultrasound wave can reflect when passing different medium faces.As long as soft tissue has 1 ‰ acoustic impedance difference, just can detect its reflection echo.Its acoustic impedance can be obviously different normally with pathological changes the time for some level of soft tissue, cause the decay of ultrasound wave in each layer of soft tissue to change, and the waveform of same echo also corresponding variation can occur.So can analyze the pathologic condition that obtains skeleton and surrounding tissue at the ultrasonic reflection echo at skeleton and different soft tissues interface.
