Abstract :
The performance of the MARS-CT has been evaluated and found to be acceptable for our soft-tissue imaging research applications. The spectroscopic response of CT number is characteristic of the relevant test materials. Corrections for beam hardening and ring artefacts are required for accurate results. Further optimization of system parameters will be required for specific applications.
