ABSTRACT:
A configuration for three-dimensional cone beam computerized tomography imaging which allows a complete data set to be acquired in a practical manner, while providing fast data acquisition to minimize motion artifacts. An object within a field of view such that every plane passing through the field of view passes through the source scanning trajectory at least once.
