Ct scan porosity

WebFor instance, the porosity values calculated from CT images with resolutions of 224 nm and 63 nm were 20.4% and 27.8%, respectively, inferring that low-resolution scanning underestimates porosity (Iacoviello et al., 2024). Moreover, nano-CT could not resolve microscopic pores that are widely distributed in shales (<50 nm).
