Design and realization of a miniaturized high resolution computed tomography imaging spectrometer

An all-reflective computed tomography imaging spectrometer

The computed tomographic imaging spectrometer (CTIS) is a passive non-scanning instrument which simultaneously records a scenes spectral content as well as its 2-D spatial. Simultaneously implies a time frame limited only by the frame rate and signal-to-noise of the imaging device. CTIS accomplishes this by feeding incident scene radiation through a computer generated hologram (CGH) in Fourier ...

High Resolution Computed Tomography

High Resolution Computed Tomography

High-resolution computed tomography

This paper investigates high-resolution reconstructions from eeciently sampled data in parallel-beam tomography, in particular local tomography. A class of sampling schemes is deened and characterized, and it is shown that the standard scheme and the interlaced scheme of Cormack are most promising. An error analysis for the ltered backprojection algorithm for both global and local tomography is...

Design of Small Animal Computed Tomography Imaging for in vitro and in vivo Studies

Introduction: Mini Computed Tomography (mini-CT) was suggested in biomedical research to investigate tissues and small animals. We present designed and built a mini x-ray computed tomography (mini-CT) for small animals as well as industrial component imaging. Materials and Methods: The system used in this study includes a X-ray tube 20kV to 160kV and a flat pa...
