A prototype table-top inverse-geometry volumetric CT system.
A table-top volumetric CT system has been implemented that is able to image a 5-cm-thick volume in one circular scan with no cone-beam artifacts. The prototype inverse-geometry CT (IGCT) scanner consists of a large-area, scanned x-ray source and a detector array that is smaller in the transverse direction. The IGCT geometry provides sufficient volumetric sampling because the source and detector...
متن کاملHolography and the inverse source problem . Part II : Inhomogeneous media
The inverse source problem for a monochromatic source imbedded in a nonabsorbing inhomogeneous medium is investigated within the framework of the reduced scalar wave equation. The Porter-Bojarski integral equation previously formulated for sources imbedded in vacuum is generalized to this case, as are the class of nonradiating and minimum-energy sources considered in Part I [J. Opt. Soc. Am. 72...
متن کاملEvaluation of the Effect of Source Geometry on the Output of Miniature X-ray Tube for Electronic Brachytherapy through Simulation
Objective: The use of miniature X-ray source in electronic brachytherapy is on the rise so there is an urgent need to acquire more knowledge on X-ray spectrum production and distribution by a dose. The aim of this research was to investigate the influence of target thickness and geometry at the source of miniature X-ray tube on tube output.Method: Five sources were simulated based on problems e...
متن کاملExploiting Multiple View Geometry in X-Ray Testing: Part II – Applications
In this paper we present four applications reported in the literature that use the theory of multiple view geometry in X-ray testing. Multiple view analysis offers advantages not only in 3D interpretation. Two or more views of the same object taken from different viewpoints can be used to confirm and improve the diagnostic done by analysing only one image. The key idea of the multiple view anal...
متن کاملDesign and Fabrication of the Mechanical Part of a Prototype Multileaf Collimator System
Introduction: Multileaf collimator (MLC) is state of the art among the radiation field shaping systems for conformal radiotherapy techniques. Some advantages of this system are as follow: reduction of treatment time, higher precision in conforming the radiation field to the projection of the target volume and lowering the chance of errors made by technologists. The purpose of this research was ...
