adj. (in computerized tomography or magnetic resonance imaging) denoting the acquisition of data when the slice thickness is similar in size to that of an individual *pixel in all planes, i.e. the *voxel is a cube. Computerized reconstruction in any plane will not suffer any loss of detail. The concept is particularly applicable for *multidetector computerized tomography, in which slice thickness of less than 1 mm is used.
(MDCT) a development of *spiral CT scanning that uses more than one array of detectors opposite the X-ray tube, so that more tissue can be included, with thinner cuts, in a single rotation of the machine. This is particularly important for three-dimensional reconstruction of tissues. It also allows volumetric scanning or *isotropic imaging, which are best achieved when the thickness of the slice is similar to the size resolution of the detectors in the other two planes. Modern CT scanners are now usually equipped with between 16 and 640 detector arrays. The technique is particularly valuable for imaging fast-moving structures, such as the heart.... multidetector computerized tomography
