Embodiment Construction
[0035] The present invention will be further described below in conjunction with specific examples and accompanying drawings.
[0036] Such as figure 1 As shown, the ultrasonic temperature measurement binary image fuzzy tracking method firstly uses the ultrasonic probe in the ultrasonic thermometer to transmit ultrasonic pulses, and receives the returned ultrasonic echoes after being fed back by human biological tissues. It is characterized in that the method also includes the following steps:
[0037] 1) The sampling frequency of the ultrasonic thermometer is N times the center frequency of the ultrasonic pulse emitted by the ultrasonic probe, where N≥8, where N is 8, and the size of the tracking window is set dx×dy accordingly, and the dx direction is the intra-frame direction. dx takes N / 2~N, so that each tracking window will not overlap in the dx direction, which can prevent some misjudgments and minimize the influence of noise. Here, dx takes 7. The dy direction is the i...
