1. A computed tomography method, comprising: determining a maximum Z location error; determining a weighted average Z location error; selecting a threshold value associated with the maximum Z location error and the weighted average Z location error; prescribing an N+1 sector reconstruction algorithm; if the maximum Z location error is less than the threshold value or the weighted average Z location error is less than the threshold value, performing an N+1 sector reconstruction; and if the maximum Z location error exceeds the threshold value or the weighted average Z location error exceeds the threshold value, prescribing an N sector reconstruction.
