  The dynamic analysis of erythrocyte deformability is used as an important
means for early diagnosis of blood diseases and blood rheology. Yet no
effective method is available in terms of three-dimensional reconstruction of
erythrocytes in a capillary. In this study, ultrathin serial sections of
skeletal muscle tissue are obtained from the ultramicrotome, the tomographic
images of an erythrocyte in a capillary are captured by the transmission
electron microscope, and then a method to position and restore is devised to
demonstrate the physiological relationship between two adjacent tomographic
images of an erythrocyte. Both the modeling and the physical verification
reveal that this method is effective, which means that it can be used to make
three-dimensional reconstruction of an erythrocyte in a capillary. An example
of reconstructed deformation of erythrocyte based on the serial ultrathin
sections is shown at the end of this paper.
