|6||7||X-ray microtomography is a powerful tool to analyze and understand internal otherwise invisible mechanisms in small animals. Resolution and duration of experiments with living specimens are currently limited by radiation damage. The quality of reconstruction is also significantly affected by the motion of the objects during the data acquisition. The compressed sensing theory has demonstrated the feasibility to recover signals from the under sampled data and, hence, opens up the possibility to reduce the radiation dose. These reconstruction techniques are computationally very demanding and have, therefore, been not used for synchrotron experiments up to now.
