Method and apparatus for two dimensional ultrasonic imaging

摘要

A method and device for ultrasonically imaging a body that includes a movable ultrasonic transducer capable of imaging a scanline wherein the scanline is fixed in orientation and spatial position relative to the movable transducer. The device contains a means for sensing transducer position information wherein the sensing means is in communication with an ultrasound console. A computing means computes the spatial position and the orientation of each scanline as the transducer is moved. The scanlines are then presented as a complete image. Alternatively, an electromagnetic transmitter and receiving sensor determine the spatial orientation and position of each scanline in free space. The method of generating a two dimensional ultrasonic image is also disclosed.
