Magnetic induction tomography (MIT) is a non-invasive modality for imaging the complex conductivity (σ) or the magnetic permeability (μ) of a target under investigation. The critical issue in the clinical application of the detection of cerebral hemorrhage is the determination of intracranial hematoma status, including the location and volume of intracranial hematoma. In MIT, the reconstruction image is used to reflect intracranial hematoma. However, in medical applications where high resolutions are sought, image reconstruction is a time- and memory-consuming task because the associated inverse problem is nonlinear and ill-posed. The reconstruction image is the result of a series of calculations on the boundary detection value, and the color of the reconstructed image is the relative value. To quantitatively and faster represent intracranial hematoma and to provide a variety of characterization methods for MIT dynamic monitoring, one-dimensional quantitative indicators are established. Our experiment results indicate that there is a linear relationship between one-dimensional quantitative indicators. The change of the detection value can roughly determine the location of the hematoma. Graphical Abstract.
磁感应断层成像（MIT）是一种用于对目标的复杂电导率（σ）或磁导率（μ）进行成像的非侵入性方法。在脑出血检测的临床应用中，关键问题是确定颅内血肿状态，包括颅内血肿的位置和体积。在 MIT 中，重建图像用于反映颅内血肿。然而，在寻求高分辨率的医学应用中，图像重建是一项耗时且耗内存的任务，因为相关的逆问题是非线性和不适定的。重建图像是对边界检测值进行一系列计算的结果，而重建图像的颜色是相对值。为了更定量、更快地表示颅内血肿，并为 MIT 动态监测提供多种特征化方法，建立了一维定量指标。我们的实验结果表明，一维定量指标之间存在线性关系。检测值的变化可以大致确定血肿的位置。图摘要。
