Abstract

It is needless to say that the nonlinear hemodynamic variables estimation is a very important study for the artificial heart. Even though it is important, there have not been satisfactory results which can be applied to the real world situations, In this paper, the problem of hemodynamic variables estimation for the moving-actuator type total artificial heart(MA-TAH) was studed. Multidimensional linear interpolation(MDI)scheme was used for the estimation. Proposed method was verified by in vitro test and showed good performance.

인공 심장의 연구에 있어서 혈류 역학 변수의 추정은 두말할 필요도 없이 매우 중요하다. 그러나 이 중요도에 견주어 볼지라도 실세계에 적용될 수 있는 연구 결과는 희박하다. 본 논문에서는 이동 작동기형 완전 인공 심장을 위한 혈류 역학 변수 추정 문제가 연구되었다. 추정 방법론으로서 다차원 선형 보간 기법을 이용하였다. 모의 순환 장치의 실험으로 제안된 방법을 검증하였으며 좋은 성능을 보였다.
