ABSTRACT:
Projection data is repeatedly acquired by a helical scan operation. Tomographic image data is repeatedly reconstructed on the basis of projection data. Generally, in a helical scan operation, in order to reduce the artifact, interpolation processing of projection data is indispensable. Tomographic image is reconstructed on the basis of acquired original projection data without performing this interpolation processing so as to meet the condition that the time required to reconstruct tomographic image data on the basis of one set of projection data required for the reconstruction of tomographic image data be shorter than that required to acquire one set of projection data. The real-time mode can therefore be introduced into a helical scan operation.
