Method for calculating and processing image of sample three-dimensional body by conic projection of, for example, x rays and three-dimensional reconstruction for inspected body utilizing the same calculating method
专利汇可以提供Method for calculating and processing image of sample three-dimensional body by conic projection of, for example, x rays and three-dimensional reconstruction for inspected body utilizing the same calculating method专利检索，专利查询，专利分析的服务。并且PURPOSE: To speedily generate a sharp image representing a threedimensional body which is being inspected by using a Gaussian weighted function instead of a function representing a support line.
CONSTITUTION: A detection cell (i) of a multidetector D decomposes a three-dimensional body as a sample as to the space of a Gaussian basic function by conical projection using an X-ray source S which irradiates the body C by a method capable of securing measuring the attenuation of radiation having passed through the body C. Then the contribution of the basic function corresponding to a volume element projected on each projection image element is calculated and each contribution is equal to the integration of the product of the basic function regarding the volume element and a function representing a support line for irradiating the corresponding image element; and the Gaussian weighted function is used for a method which processes the projected image instead of the function representing the support line. Consequently, the superior quality of the obtained result and extremely-short-time calculation are both made secure.
