A method and system for an improved data acquisition system with an image
detector array and an image processing system which finds a
malfunctioning cell, interpolates a signal for the malfunctioning cell
using neighboring channels of the cell, and corrects the interpolation
with an error rate found in performing interpolations on neighboring rows
with cells which are not malfunctioning. The image processing system may
include a DAS and a reconstruction system. The step of finding a
malfunctioning cell may be accomplished through a variety of methods,
such as measuring discrepancies between a cell's and its neighboring
cell's average readings over time and exposing the cells to x-rays which
should produce similar readings in all the cells and comparing the cells'
signals, looking for discrepancies. The step of interpolating and the
step of correcting may take into consideration cells within the same
projection view as the malfunctioning cell.
