| 摘要 |
In one embodiment, the present invention is a method for positioning an x-ray beam on a multi-slice detector array of an imaging system in which the detector array has rows of detector elements and is configured to detect x-rays in slices along a z-axis. The method includes steps of comparing data signals representative of x-ray intensity received from different rows of detector elements in first and second element subsets where the first and second subsets are located at opposite ends of the detector array and positioning the x-ray beam in accordance with a result of the comparisons.
