By a News Reporter-Staff News Editor at Journal of Technology -- New research on X-Ray Technology is the subject of a report. According to news reporting from Beijing, People's Republic of China, by VerticalNews journalists, research stated, "Fast-continuous-rotation is an effective measure to improve the scanning speed and decrease the radiation dose for cone-beam CT. However, because of acceleration and deceleration of the motor, as well as the response lag of the scanning control terminals to the host PC, uneven-distributed and redundant projections are inevitably created, which seriously decrease the quality of the reconstruction images."
The news correspondents obtained a quote from the research from the Beijing University of Aeronautics and Astronautics, "In this paper, we first analyzed the aspects of the theoretical sequence chart of the fast-continuous-rotation mode. Then, an optimized sequence chart was proposed by extending the rotation angle span to ensure the effective 2?-span projections were situated in the stable rotation stage. In order to match the rotation angle with the projection image accurately, structure similarity (SSIM) index was used as a control parameter for extraction of the effective projection sequence which was exactly the complete projection data for image reconstruction."
According to the news reporters, the research concluded: "The experimental results showed that SSIM based method had a high accuracy of projection view locating and was easy to realize."
