High-resolution computed tomography imaging: a virtual bone biopsy

High-resolution Computed Tomography for Clinical Imaging of Bone Microarchitecture

BACKGROUND The role of bone structure, one component of bone quality, has emerged as a contributor to bone strength. The application of high-resolution imaging in evaluating bone structure has evolved from an in vitro technology for small specimens to an emerging clinical research tool for in vivo studies in humans. However, many technical and practical challenges remain to translate these tech...

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...

Acute temporal bone trauma: utility of high-resolution computed tomography.

OBJECTIVE To determine the clinical utility of high-resolution computed tomography (HRCT) for temporal bone trauma evaluation and management. STUDY DESIGN Retrospective review. SETTING Level I trauma center. PATIENTS Patients (n = 105) with evidence of temporal bone trauma. MAIN OUTCOME MEASURES Statistically significant associations between HRCT, clinical, audiometric, and head CT find...
