DOI: 10.1002/nbm.3711
Abstract: Diffusion MRI has been proposed as a non‐invasive technique for axonal diameter mapping. However, accurate estimation of small diameters requires strong gradients, which is a challenge for the transition of the technique from preclinical to… read more here.

DOI: 10.1016/j.pacs.2020.100191
Abstract: The spatial resolution achievable in photoacoustic imaging decreases with the imaging depth, resulting in blurred images for deeper structures. Apart from technical limitations, the ultimate resolution limit results from the second law of thermodynamics. The… read more here.

DOI: 10.1038/s41467-019-08689-x
Abstract: The resolution of an imaging system is a key property that, despite many advances in optical imaging methods, remains difficult to define and apply. Rayleigh’s and Abbe’s resolution criteria were developed for observations with the… read more here.

DOI: 10.1038/s41598-020-73584-1
Abstract: Optical resolution of far-field optical microscopy is limited by the diffraction of light, while diverse light-matter interactions are used to push the limit. The image resolution limit depends on the type of optical microscopy; however,… read more here.

DOI: 10.1103/physreva.103.033519
Abstract: A general analytical model is established to study the change in the signal-to-noise ratio (SNR) of the spatially noisy optical signal after passing through a subwavelength-aperture system. The corresponding spatial resolution limit is redefined based… read more here.
