Differences between our THT-based and CS-based interior tomography techniques.
| A priori image model | Precisea priori knowledge | Computational essence | Angular sampling rate | Current maturity | |
|---|---|---|---|---|---|
| THT-based interior tomography | Quite general | A subregion | Inversion of truncated Hilbert data | Normal | High |
| CS-based interior tomography | Piecewise constant | Unnecessary | Minimization of total variation | Potentially low | Low |
