WebApr 19, 2024 · For each HSV-2 capsid, we calculated the particle defocus using two different methods—(i) by fitting the Thon rings calculated from the image of the whole virus and (ii) … The contrast transfer function (CTF) mathematically describes how aberrations in a transmission electron microscope (TEM) modify the image of a sample. This contrast transfer function (CTF) sets the resolution of high-resolution transmission electron microscopy (HRTEM), also known as phase contrast TEM. By … See more The contrast in HRTEM comes from interference in the image plane between the phases of scattered electron waves with the phase of the transmitted electron wave. When an electron wave passes through a sample in … See more The contrast transfer function determines how much phase signal gets transmitted to the real space wavefunction in the image plane. As the modulus squared of the real space … See more • Airy disk, different but similar phenomena in light • Optical transfer function • Point spread function See more Contrast transfer theory provides a quantitative method to translate the exit wavefunction to a final image. Part of the analysis is based on See more If we incorporate some assumptions about our sample, then an analytical expression can be found for both phase contrast and the phase contrast transfer function. As discussed earlier, when the electron wave passes through a sample, the electron beam … See more The previous description of the contrast transfer function depends on linear imaging theory. Linear imaging theory assumes that the transmitted beam is dominant, there is … See more • Contrast transfer function (CTF) correction • Talk on the CTF by Henning Stahlberg See more mercedes a class android screen
