Quizplus · Accepted Answer

Scanning a slice of tissue from multiple angles with a narrow x-ray beam,then calculating a relative linear attenuation coefficient (representing the amount of radiation absorbed in tissue for the various tissue elements in the section),and finally displaying the computed reconstruction as a gray-scale image on a television monitor is CT.
