Abstract: Embodiments of the present disclosure provide a method for constructing brain templates. First, thousands of brain MRI images are collected. Then, the collected brain MRI images are preprocessed and normalized to construct brain templates. Further, the constructed brain templates include brain templates corresponding to different age and gender groups and brain tissue probability maps corresponding to different age and gender groups. Therefore, embodiments of the present disclosure can construct brain templates by using the large sample size of brain MRI data, and support clinical applications and brain researches.

Abstract: The present invention relates to an X-ray line array detector in which a bundle of light-guide fibers is provided between an emergent surface of a scintillator and an incident surface of an array of photosensors, and the bundle of light-guide fibers has at least one bend, or an incident direction and an emergent direction are not in a same line, so that X-rays transmitting through the scintillator can not irradiate photosensors and integrated circuits behind them, and that damage resulting from long-term use or a large dose of X-ray radiation can be avoided, thereby prolonging lifetime of the line array detector.

Abstract: The present invention relates to an X-ray line array detector in which a bundle of light-guide fibers is provided between an emergent surface of a flicker body and an incident surface of an array of photosensors, and the bundle of light-guide fibers has at least one bend, or an incident direction and an emergent direction are not in a same line, so that X-rays transmitting through the flicker body can not irradiate photosensors and integrated circuits behind them, and that damage resulting from long-term use or a large dose of X-ray radiation can be avoided, thereby prolonging lifetime of the line array detector.
