A SYSTEM AND METHOD FOR DETECTION OF MOTION |
摘要 |
As part of the present invention, a motion detector (1) for detecting motion inside of a body (30) may include a first oscillator (16) to produce electrical scanning signal and a second oscillator (14) to produce an electrical Doppler signal. A vibrating element may vibrate in response to the scanning and Doppler signals. A vibration transducer may receive vibrations reflected from a structure inside the body (30) and may convert the reflected vibrations into an electrical signal. Doppler shifts between the transmitted and received vibrations may be used to estimate the velocity of the structure inside the body (30). |
