<p><P>PROBLEM TO BE SOLVED: To provide an accurate measurement of pulmonary peripheral airway with a sufficient resolution without increasing the number of images. <P>SOLUTION: An imaging system 10 includes a static member, and a rotating member rotatably connected to the static member and approaching to a rotating shaft to have an open area. The system also includes an X-ray source 14 provided in the rotating member, an X-ray detector disposed in the rotating member and constituted to receive X rays from the X-ray source, and a processor 36 communicated and connected to at least one of the X-ray source and the X-ray detector. The processor is so constituted as to, after receiving image data on an object, reconstruct a first image using the received image data 304 at a first resolution. The processor determines at least one volume of interest in the formed image and reconstruct a second image of at least one determined volume of interest at a second resolution 314. The second resolution is higher than the first resolution for promoting the quantification of the image structure. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
