DSP-based reconstruction of temperature field

In order to achieve real-time temperature reconstruction,high-end digital signal processor(DSP) was used as the computing core of simultaneous iterative reconstruction technique reconstruction algorithm.Emission spectral tomography (EST) real-time reconstruction of the temperature field was achieved.Through the experiment, the data was obtained that reconstruction algorithm needs different time under DSP system and PC system.The results indicate that using DSP as computing core,real-time EST reconstruction of temperature field can be achieved.DSP-based temperature reconstruction algorithm combined with a generic PC's control and display function is a good method for EST temperature field reconstruction.
