7/22/2008 · Even where specimens have already been isolated, tomographic methods remain of use for investigating internal structures (e.g. Donoghue et al. 2006). Additionally, ‘virtual fossil’ reconstructions have many attractions as tools for the study of three-dimensional form, even where it is accessible through conventional means.

★ ★ ★ ★ ☆

11/15/2004 · The inflection points of the pressure–volume curve have been used for setting mechanical ventilation in patients with acute lung injury. However, the lung status at these points has never been specifically addressed. In 12 patients with early lung injury we traced both limbs of the pressure–volume curve by means of a stepwise change in airway pressure, and a computed tomography (CT) scan ...

★ ★ ★ ★ ☆

A CT scan, also known as computed tomography scan, and formerly known as a computerized axial tomography scan or CAT scan, makes use of computer-processed combinations of many X-ray measurements taken from different angles to produce cross-sectional (tomographic) images (virtual "slices") of specific areas of a scanned object, allowing the user to see inside the object without cutting.

Single-photon emission computed tomography - Wikipedia

★ ★ ★ ★ ★

Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy). but is able to provide true 3D information. This information is typically presented as cross-sectional slices through the patient, but can ...
