摘要:
An X-ray imaging apparatus acquiring a differential phase contrast image of a test object without using a light-shielding mask for X-ray. The apparatus includes an X-ray source, a splitting element configured to spatially divide an X-ray emitted from an X-ray source and a scintillator configured to emit light when a divided X-ray beam divided at the splitting element is incident on the scintillator. The apparatus also includes a light-transmission limiting unit configured to limit transmitting amount of the light emitted from the scintillator and a plurality of light detectors each configured to detect the amount of light that has transmitted through the light-transmission limiting unit. The light-transmission limiting unit is configured such that a light intensity detected at each of the light detectors changes in response to a change in an incident position of the X-ray beam.

A simplified X-ray imaging apparatus is capable of computationally determining effective atomic numbers with small error factors even for light elements. In one embodiment, the X-ray imaging apparatus has an X-ray generation unit 101 (400) for generating X-rays and a detector 105 (405) for detecting X-rays transmitted through an object of examination 104 (403). A computing unit 106 (406) computationally determines a quantity of an X-ray phase attributable to the object of examination and an X-ray transmittance of the object of examination from data detected by the detector. The computing unit also computationally determines an effective atomic number of the object of examination from ρet determined from the quantity of the X-ray phase and μt determined from the X-ray transmittance.

An estimation system for estimating an injection-molding related cost comprises an input unit, storage, a data processing unit, and an output unit. The storage stores a mold estimation function for each of cost items of a mold used to produce a molded product, and a mold estimation reference value table for recording mold estimation reference values in association with prescribed conditions. The data processing unit acquires a fabrication condition of the molded product through the input unit, reads the mold estimation function and one of the mold estimation reference values from the storage corresponding to the fabrication condition, and estimates a cost of the mold based on the mold estimation function and the selected mold estimation reference value. The output unit outputs a mold cost estimation result made by the data processing unit.
