METHOD AND APPARATUS FOR COLLECTING PER- FECT RADON DATA FOR THREE-DIMENSIONAL CALCULATOR TYPE TOMOGRAPHIC IMAGE REPRODUCION

摘要

PURPOSE: To precisely regenerate the image of a part of concern without lowering the quality by performing a scanning along the upper limit and lower limit of a support area within an object space surrounding a part of concern, partitioning an integrated surface corresponding to data, and selectively operating the collected data. CONSTITUTION: According to whether an optional integrated surface, for example, a flat surface, crosses a part of concern and either one of the upper area from an upper limit boundary and the lower area from a lower limit boundary, data are selectively ignored by the operation of partitioned data, whereby an undesirable contribution is removed. Further, according to whether the optional integrated surface, for example, the flat surface crosses the part of concern and both the upper area from the upper limit boundary and the lower area from the lower limit boundary, the data are selectively combined, whereby the contribution which is lost in other cases is recovered. In this way, the undesirable contribution is removed, and the fallen out information is recovered, whereby the radon space is precisely filled to form a prefect data assembly.
