0602957HeThe project proposes to develop a novel non-ionizing, cost effective and high resolution imaging modality for imaging electrical impedance by integrating ultrasound with electromagnetism (Magnetoacoustic tomography with magnetic induction or MAT-MI). The specific aims are to: 1) develop theoretical foundations for MAT-MI imaging, and novel image reconstruction algorithms for high-resolution imaging of electrical impedance within biological tissue; 2) conduct well-controlled computational simulation studies to evaluate and test the performance of MAT-MI in reconstruction of electrical impedance from the acoustic signals; 3) develop a novel 3-D MAT-MI system for imaging electrical impedance in biological tissues; and 4) conduct well-controlled experimental studies to assess the feasibility of MAT-MI to obtain high resolution images of electrical impedance.

0602957 He该项目提出开发一种新型的非电离、成本效益高的高分辨率成像模式，通过将超声与电磁相结合（磁感应磁声断层扫描或MAT-MI）来成像电阻抗。具体目标是：1）开发MAT-MI成像的理论基础，以及用于生物组织内电阻抗的高分辨率成像的新型图像重建算法; 2）进行良好控制的计算模拟研究，以评估和测试MAT-MI在从声信号重建电阻抗中的性能; 3）开发用于生物组织中电阻抗成像的新型3-D MAT-MI系统;以及4）进行良好控制的实验研究以评估MAT-MI获得高分辨率电阻抗图像的可行性。
