An optimal measurement selection strategy based on incoherence among rows (corresponding to measurements) of the sensitivity (or weight) matrix for the near infrared diffuse optical tomography is proposed. As incoherence among the measurements can be seen as providing maximum independent information into the estimation of optical properties, this provides high level of optimization required for knowing the independency of a particular measurement on its counterparts. The proposed method was compared with the recently established data-resolution matrix-based approach for optimal choice of independent measurements and shown, using simulated and experimental gelatin phantom data sets, to be superior as it does not require an optimal regularization parameter for providing the same information.
提出了一种基于近红外漫射光学层析成像灵敏度（或权重）矩阵中行（对应测量）之间不相关性的最佳测量选择策略。由于测量之间的不相关性可以看作是对光学性质估计提供最大独立信息，这为了解特定测量与其对应测量的独立性提供了所需的高级优化。该方法与最近建立的基于数据分辨率矩阵的最佳独立测量选择方法进行了比较，并使用模拟和实验明胶体数据集进行了验证，结果表明该方法更优，因为它不需要最佳正则化参数即可提供相同的信息。
