Because tomosynthesis can reconstruct any tomographic image from a series of acquired X-ray images, it can be used to observe bone fractures that are difficult to see with radiography, by avoiding overlapping bones or tissues at any partic-ular height. However, conventional tomosynthesis requires a flat panel detector (FPD) that supports serial radiography and an imaging system with precision mechanical control mechanisms, which limit the number of usable systems. Therefore, to promote the widespread use of tomosynthesis, the “Universal Tomosynthesis” method was developed. It enables tomosynthesis using an X-ray system that does not include a serial radiography-capable FPD or precision mechanical  control, by using the X-ray radiography system in combination with a specialized UT-Phantom positioning phantom that predicts imaging system alignment and dedicated UT-Station tomographic imaging software.
