EIT装置を用いた生体組織解凍過程の3次元モニタリング

抄録

In this study, thawing of biological tissue was tried monitoring using three dimensional electrical impedance tomography (EIT). To measure three dimensional throwing process, a printed circuit board was developed. It contained a circular measurement hole with 5mm in diameter and included four layers of eight electrodes arrays individually. A frozen columned beef was set at the center of the measurement hole and thawing process could be observed real-timely. The EIT measured from bottom layer showed the fastest throwing of frozen columned beef where had highest thermal conductivity. And other EITs from upper layers showed slower thrawing. Results showed feasibility of three dimensional monitoring of thawing using EIT.
