Abstract
An imaging system is provided which comprises: a CT scanner; a first storage unit storing a plurality of transverse images taken by the CT scanner; an image conversion unit producing a two-dimensional cross sectional image on the basis of the transverse images, for which the transverse images are arranged in a direction perpendicular to a transverse plane; a second storage unit storing the cross sectional image; a peak detection unit extracting an outline of the cross sectional image for detecting peaks or troughs of the outline; a peak interpolation unit carrying out interpolation on the basis of a specified standard for an outline between the peaks or between the troughs detected by the peak detecting unit; and an image construction unit reconstructing the cross sectional image stored in the second storage unit using the outline interpolated by the peak interpolation unit. The imaging system makes it possible to improve a precision and to increase a speed in peak detection when reconstructing a coronal image produced from a plurality of transverse images taken by a CT scanner.
