Revitalized old technology spurs new interest, applications

August 01, 2007 | Musculoskeletal Imaging [1], Vendors [2] Although the roots of traditional geometric x-ray tomography date back to the 1930s, the technique was not practical at that time because image receptors could not provide large-area dynamic scanning. The technique, renamed tomosynthesis in the 1970s, acquired only one imaging section at a time, requiring additional time and radiation dose to obtain more imaging sections. It's not hard to understand why, therefore, plain-film tomosynthesis fell by the wayside as soon as CT came along.
