Abstract
Nowadays multi-modality imaging has gained great interest in biology research by offering complementary information. In this paper, a modularly designed fluorescence molecular tomography (FMT) system has been developed, which can be not only used as a standalone imaging device, but also feasibly integrated with other imaging modalities, such as X-ray computed tomography (X-CT), single photon emission computed tomography (SPECT) and positron emission tomography (PET), to perform multi-modality imaging in a sequential manner. The system rotates the CCD camera and the excitation light source in the vertical plane, while the animal is stationed on a horizontally moveable transparent animal holder at its natural prone position. FMT and other imaging modalities are co-registered automatically. Phantom and animal experiments have been carried out to demonstrate the performance of the system. The accurate results show that this innovative flexible FMT system has a great potential to be a powerful tool for the study of small animal disease models.
