The invention relates to a method and system for automatically identifying video content within source video and transmitting the video content to an electronic mail client. The graphical code reader includes control circuitry for the graphical code reader and a multi-functional optical element in electronic communication with the control circuitry. Acquisition of projection images and construction of three-dimensional images is continued during the insertion of the needle into the breast, during positioning the needle towards the coordinate point, during the sampling and after the sampling. 29n1n2, where n1 is the refractive index of the diffraction grating and n2 is the refractive index of the embedding layer.
