Research Abstract |
To reconstruct three-dimensional(3D) structure of proteins, we have developed newly 3D reconstruction algorithm and a high-contrast detection system of the biological samples. Our 3D reconstruction method was composed with the modified Simulated-Annealing algorithm with the high accuracy classification method of the class averages from the protein images by the transmission-electron microscopy. This method enables automatically 3D reconstruction from the protein images. Furthermore, we developed high-contrast and low-damage 3D detection system. This system contains a linear array PD system and new 3D reconstruction method.
