We present mathematical and numerical models for SPECT imaging, as an example of application where a description in terms of structured matrices seems attractive for reducing the high complexity of the reconstruction problem. We discuss how structures can be incorporated in the models and we suggest some computational techniques in order to exploit them.

Abstract
We present mathematical and numerical models for SPECT imaging, as an example of application where a description in terms of structured matrices seems attractive for reducing the high complexity of the reconstruction problem. We discuss how structures can be incorporated in the models and we suggest some computational techniques in order to exploit them.
