Methods and apparatus for computed tomography scanning using a two-dimensional radiation source |
摘要 |
A method for collecting computed tomography (CT) scan data includes positioning a gantry at a first position, collecting a partial inverted-cone beam projection at a first detector cell at the first gantry position such that the first detector cell defines a focusing position in space, and collecting data from a second detector cell different from the first detector cell as the gantry rotates such that the focusing position remains substantially stationary in space.
