  Computerized Tomography assembly and system configuration are optimized for
enhanced invertibility in sparse data reconstruction. Assembly generating
maximum principal components/condition number of weight matrix is designated as
best configuration. The gamma CT system is used for testing. The unoptimized
sample location placement with 7.7% variation results in a maximum 50% root
mean square error, 16.5% loss of similarity index, and 40% scattering noise in
the reconstructed image relative to the optimized sample location when the
proposed criteria are used. The method can help to automate the CT assembly,
resulting in relatively artifact-free recovery and reducing the iteration to
figure out the best scanning configuration for a given sample size, thus saving
time, dosage, and operational cost.
