The Linear Dependence of Rows in a System Matrix Generated by the Strip-Based Projection Model in CT
Let Cu = h be a linear system generated along two distinct scanning directions by the strip-based projection model in CT, where C is a binary row-rank deficient matrix. We identify the linearly dependent rows explicitly. The removal of these linearly dependent rows results in a full-rank matrix. Consequently, the computational cost for image reconstruction is reduced. An open problem will be given.
