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...

Role of High Resolution Computed Tomography in the Diagnosis of Interstitial Diseases of the Lungs

Background: Interstitial lung diseases are a diverse group of diseases that predominantly affect the lung interstitium and share similar clinical and radiological manifestations. Most patients have nonspecific respiratory complaints and the first suggestion of the disease is usually by a chest radiograph. However many patients of interstitial lung disease can have a normal chest radiogram; in t...

Use of high resolution computed tomography of the lungs in patients with rheumatoid arthritis.

OBJECTIVE To assess the usefulness of high resolution computed tomography (HRCT) of the lungs in patients with rheumatoid arthritis (RA) with and without respiratory symptoms. PATIENTS AND METHODS Eighty eight RA patients with a mean duration of disease 12 (SD 8) years were evaluated. Eleven patients were excluded because of previous exposure to silica. The 77 remaining patients formed two gr...
