International Journal of Biomedical Imaging, 2014 Objective. Sentinel node biopsy in patients with cutaneous melanoma improves staging, provides prognostic information, and leads to an increased survival in node-positive patients. However, frozen section analysis of the sentinel node is not reliable and

Multispectral Live‐Cell Imaging [PDF]
Current Protocols in Cell Biology, 2018 AbstractFluorescent proteins and vital dyes are invaluable tools for studying dynamic processes within living cells. However, the ability to distinguish more than a few different fluorescent reporters in a single sample is limited by the spectral overlap of available fluorophores.

Multispectral imaging the sun in the ultraviolet [PDF]
2009 First Workshop on Hyperspectral Image and Signal Processing: Evolution in Remote Sensing, 2009 Solar images in the ultraviolet (UV) are the key to the understanding of the highly dynamic and energetic solar atmosphere. Nowadays, several missions provide simultaneous observations in multiple wavelengths. Such multispectral images have traditionally been used as inputs to physical models.
