電気・超音波マルチイメージングにおけるインピーダンス推定精度の向上

抄録

Electrical impedance imaging is an emerging medical imaging technique which can produce tomographic images of impedance properties. Many fusion systems in which impedance imaging combined other modalities are developed, but no technique currently exists the multi imaging system that could simultaneous imaging of the same region. To realize the multi-imaging systems, an improved fusion impedance imaging technic with electrical and ultrasonic multi-imaging system is developed. Especially, this paper investigates the accuracy effects against the increasing sensor number and proposes an improved parameter adjustment method. The numerical simulation and the practical experiment are conducted on the assumption the breast cancer. The imaging result shows the accuracy of estimating impedance can be improved by the increasing the sensor number and the modification of the parameter setting.
