COMPUTERIZED METHOD AND DEVICE FOR TOMOGRAPHIC IMAGE PICKUP
Document Type and Number:
Japanese Patent JPH07178079
Kind Code:
A
Abstract:
PURPOSE: To eliminate the problem of introduction errors in a scanner by collecting and interpolating views around a cubage at a remarkable point in the patient during axial motion of an object to be irradiated in order to cyclic motion of an X-ray source so as to reconstitute the views as a three-dimensional image reemergence. CONSTITUTION: The relationship between a radioactive ray source 12 and an object to be irradiated, are interchanged so as to irradiate the object to be irradiated by a radioactive ray detector 24, along a spiral locus, spiral data sets each including a plurality of a progressive and temporal and alternative view of image data is obtained. In a time in which a plurality of temporal and alternative spiral data sets of thus obtained respective data sets are produced, the above-mentioned steps are repeated so as to reconstitute a three- dimensional image reemergence which is spatially, interpolatively and temporally alternated. A temporal interpolation with respect to data selected from three image reemergence which has been temporally distorted is selected in consistent with a common time.
