Maximizing temperature sensitivity in a one-dimensional photonic crystal thermal sensor

open access: yesScientific Reports
This paper focuses on a defective one-dimensional photonic crystal thermal sensor with fabricated layers of gallium nitride, glycerin, and air. The transmission features of this sensor have been presented based on the transfer matrix approach using ...

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

The effectiveness and cost-effectiveness of computed tomography screening for coronary artery disease : systematic review [PDF]

open access: yes, 2006
Coronary heart disease (CHD) is one of the main causes of mortality and morbidity in the UK and other Western countries. The disease can be asymptomatic until the first event, which may be a fatal myocardial infarction (heart attack).

Inconsistency in 9 mm bullets : correlation of jacket thickness to post-impact geometry measured with non-destructive X-ray computed tomography [PDF]

open access: yes, 2014
Fundamental to any ballistic armour standard is the reference projectile to be defeated. Typically, for certification purposes, a consistent and symmetrical bullet geometry is assumed, however variations in bullet jacket dimensions can have far reaching ...

New Inversion Formula for the X-ray Transform and its Application to CT reconstruction

open access: yes, 2022
S.315-318We present an inversion formula for the X-ray transform that differs in many ways from well-known results: The formula is valid for arbitrary dimensions and provides therefore an uniform approach for fan- and cone-beam Computerized Tomography ...

Fast Projection Matching for X-ray Tomography

open access: yesScientific Reports, 2017
X-ray 3D tomographic techniques are powerful tools for investigating the morphology and internal structures of specimens. A common strategy for obtaining 3D tomography is to capture a series of 2D projections from different X-ray illumination angles of ...
