【摘要】 光学医学成像方法可分为两大类，即直接法和间接法。对于厘米级以上的软组织，由于早期到达光的比例极小，因此在安全曝光量下直接法是不现实的。目前广泛流行的间接法则利用全部可探测到的光能，通过求解特定光子模型的逆问题实现图像的重建，是有望实现临床光学医学成像的方法之一。本文综述了近红外光辐射医学成像研究中间接成像法所涉及的实验技术更多还原

【Abstract】 The methodologies of diagnostic optical imaging can be divided into two categories:direct method and indirect method.For the soft tissue with a thickness greater than 1 cm,the direct method using a safe dose of radiation is inappropriate for the scarcity of early arrived photons.The flourishing indirect method employs the whole profiles of the measured TPSFs to accomplish a tomographic imaging by solving the inverse problem of a given photon propagation model,and is regarded as one of the most promising method for clinic implementation to optical tomography.This paper addresses the experimental schemes of indirect optical imaging.更多还原
