• MR compatible SPECT
• CdTe/CZT
• Hybrid pixel-waveform readout
• System development

In this paper, we will report the development of an ultrahigh resolution MR-compatible SPECT system that can be operated inside a pre-existing clinical MR scanner for simultaneous dual-modality imaging of small animals. This system is constructed with 40 small-pixel CdTe detector modules assembled in a fully stationary ring SPEC geometry. We have experimentally demonstrated that this system is capable of providing an imaging resolution of <500 mu m when operating inside MR scanners. We will report the design, construction of the MRI-compatible SPECT system, including the detector technology, collimator, system development and so on The first imaging results obtained with this newly constructed SPECT system will also be reported.
