摘要:
A method and apparatus are provided to reconstruct projection data obtained from CT imaging devices with offset detector geometries. According to one aspect of the present invention, a method is provided to reconstruct projection data obtained from CT imaging devices with offset detector geometries that includes the following steps: (i) matching projection data measured at opposing sides of the acquisition trajectory and splicing them together to generate a full, non-truncated projection data set (ii) differentiation of the projection data (iii) filtering the differentiated projection data with a filter, such as for example a Hilbert filter (iv) applying redundancy weighting to the filtered projection data and (v) back-projecting the redundancy weighted projection data to generate image data.
