ABSTRACT:
An imaging method of an X-ray computerized tomography (X-ray CT) comprising the steps of reconstructing a partial region including a region of interest from penetrating data of an object, extracting only shape information from the reconstructed image, setting a threshold function determined by resolution to the reconstructed image information which is equivalent to linear absorption coefficient distribution (density), extracting the reconstructed image information by making the information into bi-values or tri-values based on the threshold function or by differentiating the information, and extracting and imaging only a portion where the linear absorption coefficient distribution (density) changes stepwise.
