In addition to providing useful visual information, computed tomography (CT) can also be
used for estimating tissue density. In the case of the lung, a structure exhibiting a wide …

SUMMARY CT densitometry of the lung is a sensitive and readily available noninvasive
method for determining regional and global lung density. Automated computer analysis …

Computed tomography scanners can be calibrated to provide reproducible measurements
for a quantitative analysis of lung density. Typical histograms for inspiration and expiration …

Lung tissue, blood, and air determine the physical density of the lung and hence the
attenuation measured on CT scans. These components are not homogeneously distributed …

The current level of computed tomography (CT) scanner resolution is such that CT is
possibly the best radiographic procedure available for viewing gross pulmonary anatomy …

Computed tomographic (CT) lung density measurements were prospectively correlated with
pulmonary haemodynamic data in 33 patients with chronic heart disease. Cardiac …

Preliminary work has shown that normal lungs have predictable CT patterns and density
ranges. In emphysema, there are irregular zones of extremely low density as well as an …

We studied 80 subjects (63 M, 17 F; 23-82 yrs) and related lung computerized tomography
(CT) density with age, height, spirometry, lung volumes, diffusing capacity and arterial blood …

Background Objective quantification of emphysema using computerized tomography (CT)
density measurements is rapidly gaining wide acceptance as an in vivo measurement tool …

In order to achieve practical application for the treatment planning of radio therapy, lung
density was assessed by means of CT. Cork phantoms were meas ured 360 times to test the …
