A kind of hybrid imaging system includes that the first imaging system is configured to obtain the low resolution anatomical data anatomical structure of the first visual field. Second imaging system is configured as obtaining the anatomical structure of the first visual field of functional data. Reconstruction processor is configured as the image that Reconstruction of The Function data are converted into correction for attenuation based on attenuation data. In response to showing the described through correction for attenuation of area-of-interest, the first imaging system or another imaging system obtain one or more parts of high-resolution data, and the first visual field includes area-of-interest. Reconstruction processor rebuilds high-resolution anatomical data to one or more high-resolution area-of-interests.
