The images and position and orientation data are thereafter recorded.

Abstract: A method of transmitting scan data from an ultrasonic scanning device to a computer. A desired number of individual scan images are acquired as frames within a buffer, after which the contents of the buffer are frozen. The number of frames in the frozen buffer are counted, and the dimensions and pixel format of each frame in the frozen buffer are determined. The frames from the scanning device are transmitted to the computer via a connection device, and the transmitted frames are written to an image file in a sequential manner.
