Fundamental Concepts Related to Laser Molecular Imaging

Laser molecular imaging deals with analyzing the spatial distribution and temporal variation of biomolecules in a human body and samples of a biological origin. Similar studies are associated with the discovery and analysis of biomarkers. Suitable biomarkers are vital for monitoring a person’s current metabolism and disease detection, but the dependence of a disease, a shift in metabolism, and registered spectral data are latent and complicated. Accordingly, specific methods of spectral data analysis are necessary. Currently, artificial intelligence is the most promising approach in this field. This chapter gives general information about the biomarker conception, molecular laser imaging, and artificial intelligence, including machine learning. The basic concepts introduced here are described in detail in Chapters 2–4.
