Dimensional X-ray Computed Tomography and its Evaluation Method of Measurement Capability

چکیده
An X-ray computed tomography (CT) system that is capable of dimensional measurements is incleasingly propergating in our life because the realization of simultaneous nondestructive dimensional measurements for outward forms and inward forms on dense spatial points in short time duration remarkably facilitates production loop. However, the X-ray CT is still not applicable to all of industrial object to date. National metrology institute of Japan have been continued performance evaluation of Xray CT to understand the dimensional metrology by X-ray CT. Examples of test procedure using simple shaped objects and trial measurements on realistic objects are presented.

Assessment of X-Ray Crosstalk in a Computed Tomography Scanner with Small Detector Elements Using Monte Carlo Method
Introduction: Crosstalk is a leakage of X-ray or light produced in a matrix of X-ray detectors or array of photodiodes in one element to other elements affecting on image contrast and spatial resolution. In this study, we assessed X-ray crosstalk in a computed tomography (CT) scanner with small detector elements to estimate the effect of various parameters such as X-ray tube voltage, detector e...
متن کاملThe Application of Voxel Size Correction in X-ray Computed Tomography for Dimensional Metrology
X-ray computed tomography (CT) is a non-destructive, radiographic scanning technique that enables the visualisation and dimensional evaluation of both internal and external features of a workpiece; it is therefore an attractive alternative for measurement tasks that prove problematic for conventional tactile and optical instruments. The data output of a CT measurement is a volume of grey value ...

Introduction: To date, gold nanoparticles (GNPs) have been demonstrated to have great potential as contrast agent for CT imaging and therapeutics. This study was designed to evaluate any effect on X-ray attenuation that might result from using GNPs with a variety of size, surface chemistries and shapes. Materials and Methods: Spherical GNPs and gold nanorod...

Background: We used a MapCHECK software-based dimensional dose distribution comparison method capable of evaluating point-to-point geometrical dose differences in volume to determine whether doses obtained from an enhanced computed tomography (CT)-based treatment plan, which better defines the target regions and organs at risk, differs from doses obtained from plain CT and then evaluated the fe...
متن کاملAn iterative method to estimate x-ray attenuation coefficients in computed tomography
Introduction: The basis of image formation in Computed Tomography (CT) lies in the x-ray linear attenuation coefficient of the scanned material. Compton scattering and photoelectric effect are the dominant interactions of the x-ray photons with the subject, in the range of diagnostic radiology. These two coefficients are important in tissue characterization by Dual-Energy CT (D...
