A woundless blood cell parameter quantitative determination method adopts optical coherent tomographic (OCT) imaging technology. Living body tissue blood vessel is irradiated with wide band laser source in different depth for local focusing and image infusing reconstruction, 3-D OCT images of various blood cells are obtained in different tomographic depth of vessel. By the analysis and calculation of the OCT images, the characteristic 3-D structure information, and quantized characteristic and parameters of corresponding blood cells, including erythrocyte, leucocyte and blood platelet are obtained. The present invention is favorable to diagnosis and treatment of diseases. |
