Typically in optical microscopy, the signal-to-noise ratio (SNR) is calculated to quantify the image contrast which indicates how well different regions of interest in the image can be differentiated.
Ultrawidefield fundus (UWF) images have a wide imaging range (200° of the retinal region), which offers the opportunity to show more information for ophthalmic diseases. Image quality assessment (IQA) ...
Although contrast agents have an essential role in non-invasive imaging techniques, potential side effects limit their use. For example, both low- and iso-osmolar iodinated contrast media used in ...
