multidetector computerized tomography

multidetector computerized tomography
= 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 multiplanar reconstruction, which is best achieved when the thickness of the slice is similar to the size resolution of the detectors in the other two planes. This is known as isotropic imaging and occurs with slice thicknesses around 1 mm. Modern CT scanners are now usually equipped with at least 16 detector arrays. The technique, which is also called multislice computerized tomography (MSCT), is particularly valuable for imaging fast-moving structures, such as the heart.
