Thoracic Sarcoidosis: Imaging with High Resolution Computed Tomography

Thoracic high resolution computed tomography (HRCT) in asthma.

INTRODUCTION High-resolution computed tomography (HRCT) is a widespread medical imaging method for the study of thoracic diseases. In asthma it is very useful particularly when it is difficult to achieve an effective control of disease, and in severe deterioration. AIM It was intended to evaluate the imaging changes by HRCT in asthmatic patients and to assess the expression according to the s...

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...

Advanced NDT with high resolution Computed Tomography

In today’s quality market, achieving the smallest feature recognition possible in the inspection process has become a higher priority than ever before. Due to complex geometries and miniaturization of many high reliability components in the automotive, electronics and aerospace industries, achieving this level of feature recognition has also become increasingly difficult. Due to inherent limita...
