  • It is needless to say that the hemodynamic variables estimation is a very important study or the artificial heart. Even though its importance there have not been satisfactory results which can be applied to the real-world situations. In this paper, we propose a practical afterload model ( AoP, PAP) which can be applied to the real-world situation.

  • The quantitative comparison of brain architecture across different subjects requires a common coordinate system, with respect to which the spatial variability of features form different individuals can be expressed. We have developed and implemented an image warping technique which is based on an elastic body deformation. The resulting 2D deformation map can be used to quantify anatomic differences between subjects. The technique's accuracy is tested, by warping 2D magnetic resonance images of age seventies into Talairach atlas.

  • This paper presents the development of depth extraction algorithm or the 3D Endoscopic Data using a stereo matching method and depth calculation. The purpose of other's algorithms is to reconstruct 3D object surface and make depth map, but a one of this paper is to measure exact depth information on the base of [cm] from camera to object. For this, we carried out camera calibration.

  • Various Endoscope Video System have been introduced and used at wide fields in our country. But this system doesn't have fuction available for recording of Video and Audio data at a time. So many problems were caused by this point, like loose of data accuracy, time and manpower consumption for re-editing prodedure and so on. For solving these problems, we made and modified some systems considering economical and practical aspects and tried to lift up efficiency of clinical usage.
