2.1
The EOS 2D/3D imaging system (EOS Imaging – formerly Biospace Med) is a novel device that produces 2D images similar to those derived by conventional means as well as 3D reconstructions for some bony body parts. It differs from conventional film, computed, and digital radiography systems in several respects. First, it uses slot-scan technology (that is, scanning a line at a time rather than taking the entire image at the same instant) to vertically scan all or part of the body in a weight-bearing position. Second, it takes simultaneous images in 2 planes (PA and lateral). Third, by using computer models, it can construct 3D surface images from the simultaneous 2-plane images. Additional details are provided in section 4.
