US Patent 7555100 Long length imaging using digital radiography

A method for long length imaging with a digital radiography apparatus. Setup instructions are obtained for the image and a set of imaging positions is calculated for an exposure series according to the setup instructions. An operator command is obtained to initiate an imaging sequence. The imaging sequence is executed for each member of the set of imaging positions in the exposure series by automatically repeating the steps of positioning a radiation source and a detector at a location corresponding to the specified member of the set of imaging positions and obtaining an image from the detector at that location and storing the image as a partial image. The long length image is generated by combining two or more partial images.
