Chest imaging by high-resolution computed tomography (HRCT)

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...

Chest High Resolution Computed Tomography Findings in Connective Tissue Diseases

BACKGROUND Lung disorders are important for prognosis of connective tissue disease (CTD). Thus, chest radiography, High Resolution Computed Tomography (HRCT) of the chest and ultrasonic echocardiogram are suggested after the diagnosis of these conditions. The purpose of this study was to evaluate chest HRCT findings in patients with CTD. MATERIALS AND METHODS In this descriptive cross-section...

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...
