Control system of space and time distribution of laser radiation on the basis of liquid crystal modulator for diagnostics and treatment of malignancies with the aid of photodynamic therapy method

摘要

Abstract: The complex for tumor diagnostics and therapy on the basis of spatial-temporary light modulators (STLM) conjugated with laser, gastroscopy, videocamera on the base of CCD- matrix and computer is assembled. The choice of modulator operating mode permits us to achieve many effects, in particular, to make a contour radiating area, to provide a more intensive effect on the border of the center of pathology and to redistribute the emission intensity on the surface of pathologic tissue. The work of STLM and dependencies its characteristics from different parameters in full is described.!10
