Abstract

The application discloses a kind of ultrasonic phased array encoding scanning three-dimensional real-time imaging method, comprising the following steps: step one: setting scanning parameter and imaging parameter;Let i=1;Step two: drive ultrasonic phased array array probe along the scanning direction moves, when encoder triggers data acquisition, the ultrasonic detection data of the i scanning position is collected, obtains the i S scanning imaging;Step three: the i S scanning imaging is converted into the i slice data, to update the i slice of volume data with the i slice data;Step four: based on the relative position relationship between observation point, volume data and projection plane, using ray casting algorithm processing volume data, obtains the real-time three-dimensional imaging based on ultrasonic phased array encoding scanning;Step five: judge whether need to continue to be measured object ultrasonic scanning: if yes, then execute step six;If not, then execute step seven;Step six: let i=i+1, step two is executed cyclically;Step seven: end ultrasonic scanning.
