X-Ray Luminescence and X-Ray Fluorescence Computed Tomography: New Molecular Imaging Modalities

open access: yesIEEE Access, 2014
X-ray luminescence and X-ray fluorescence computed tomography (CT) are two emerging technologies in X-ray imaging that provide functional and molecular imaging capability. Both emission-type tomographic imaging modalities use external X-rays to stimulate

Meaning of Interior Tomography [PDF]

open access: yes, 2013
The classic imaging geometry for computed tomography is for collection of un-truncated projections and reconstruction of a global image, with the Fourier transform as the theoretical foundation that is intrinsically non-local. Recently, interior tomography research has led to theoretically exact relationships between localities in the projection and ...

Ring artifacts removal in X-ray-induced acoustic computed tomography

open access: yesJournal of Innovative Optical Health Sciences, 2022
X-ray-induced acoustic computed tomography (XACT) is a hybrid imaging modality for detecting X-ray absorption distribution via ultrasound emission. It facilitates imaging from a single projection X-ray illumination, thus reducing the radiation exposure ...

Two-view topogram-based anatomy-guided CT reconstruction for prospective risk minimization

open access: yesScientific Reports
To facilitate a prospective estimation of the effective dose of an CT scan prior to the actual scanning in order to use sophisticated patient risk minimizing methods, a prospective spatial dose estimation and the known anatomical structures are required.
