Functional imaging (or physiological imaging) is a medical imaging technique of detecting or measuring changes in metabolism, blood flow, regional chemical composition, and absorption. As opposed to structural imaging, functional imaging centers on revealing physiological activities within a certain tissue or organ by employing medical image modalities that very often use tracers or probes to reflect spatial distribution of them within the body. These tracers are often analogous to … WitrynaIn this paper, we propose a BCEM with full Stokes polarization imaging function in a wide field of view, the schematic diagram is shown in Figure 1(d). The BCEM consists of a bifocal metalens array, where three bifocal metalens form a sub eye. The three bifocal metalens that make up the sub eye are denoted by the symbols X/Y, 45/135 and R/L ...
