Methods and apparatus for submillimeter CT slices with increased coverage |
摘要 |
One embodiment of the present invention is a method for imaging an object using a multi-slice computed tomography (CT) imaging system having a radiation source and a detector, the detector having a plurality of detector rows configured to acquire projection data from a scanned object between the radiation source and the detector, wherein each of the detector rows is perpendicular to and has a thickness in a z-direction. The method includes steps of collimating a radiation beam from the radiation source into a plurality of separate beam portions transverse to the z-direction so that the separate beam portions pass through the object and impinge on the detector rows; scanning the object using the plurality of separate beam portions to acquire projection data; and reconstructing an image of the object utilizing the acquired projection data.
