Abstract
In conventional computed tomography slices are 10 mm thick and scans are obtained at 10 mm intervals; in high resolution computed tomography slices are 1-2 mm thick and scans are obtained at 10-40 mm intervals. The images therefore represent only one tenth or less of the volume of the lung. This sampling is suited to diffuse processes affecting extensive areas of the lung but will clearly miss small lesions lying between slices. High resolution computed tomography can resolve an object of 0.5 mm diameter and is ideally suited for use in the lungs, where a high contrast between tissue and air exists.2
