Hard-Tissue Debris Accumulation Analysis by High-Resolution Computed Tomography Scans

Hard-tissue debris accumulation analysis by high-resolution computed tomography scans.

INTRODUCTION Hard-tissue debris accumulation is a potential side effect of root canal instrumentation that has not been systematically investigated. In the current communication, a method to assess this debris using high-resolution microcomputed tomography (microCT) is presented. METHODS Based on prescans, mandibular molars with joining mesial root canals and isthmuses between these were sele...

High resolution pulmonary computed tomography scans quantified by analysis of density distribution: application to asbestosis.

A new method for quantitative evaluation for high resolution computed tomography (HRCT) of the lungs was developed by assessment of the distribution of radiological densities within the lung slices. To enable effective reduction of data and improve the sensitivity of detection of abnormalities, the density distributions were analysed by curve fitting through the gamma variate model. The output ...

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...
