摘要： An X-ray CT apparatus comprising a scanner that includes an X-ray source and an X-ray detector having two-dimensionally arranged X-ray detector elements, disposed on the opposite side of the subject to the X-ray source and carries out helical scanning around the revolving axis and an image processor for creating a tomogram of the subject from the data collected by helical scanning using the X-ray detector, wherein the image processor creates a tomogram by reconstructing an image from data on the subject including a plurality of sets of projection data of different phases of helical scanning at the same point on the revolving axis and adding the reconstructed images of different phases, whereby a good image is created while suppressing aritifacts.

摘要： A multi-slice x-ray CT apparatus has detectors arranged in rows, and projection data on a cross section of an object can be simultaneously measured, wherein the spiral pitch can be arbitrarily determined. A virtual detector row is virtually defined to compensate for lack of lines if the spiral pitch is larger than the number of pitches, so as to always create a high-quality image even if the relationship between the number of rows of detectors and the spiral pitches changes. The weight determined for the virtual detector row is distributed to the weights of projection data on the actual detectors used when the projection data on the virtual detector row is determined.
