Title:
IMAGE RECONSTRUCTION METHOD AND X-RAY CT APPARATUS
Document Type and Number:
Japanese Patent JP2006034865
Kind Code:
A
Abstract:
To acquire a CT image of a desired cross section even if internal organs of a subject carry out position slippage by inertia according to acceleration or deceleration of table transfer at the time of a helical scan.
Image reconstruction is carried out by rectifying a reconstruction aspect P to a reconstruction plane R according to position slippage by the inertia of the internal organs I of the subject H which rides on a cradle 12 which carries out straight line transfer at the time of the helical scan. According to this invention, the CT image of the desired cross section can be acquired even if the internal organs of the subject carry out the position slippage by the inertia.
