Called dynamic digital radiography (DDR), DDR is an enhanced version of a standard DR system designed to acquire up to 15 sequential radiographs per second for up to 20 seconds of physiological movement. The result is 300 x-ray images acquired with a dose equivalent to approximately two standard x-rays. The goal is to allow clinicians to observe the dynamic interaction of anatomical structures, such as soft tissue and bone, with physiological changes over time.
DDR may be particularly promising for use in thoracic imaging because it allows clinicians to observe chest wall, heart, and lung motion during respiration, the company said. Konica Minolta is also exploring the technology in orthopedic applications for the spine and extremities.
DDR can also perform conventional x-ray studies, along with the radiographic studies with motion. The technology has not yet received clearance from the U.S. Food and Drug Administration (FDA).
