A real image is the collection of focus points actually made by converging/diverging rays, while a virtual image is the collection of focus points made by extensions of diverging or converging rays. In other words, a real image is an image which is located in the plane of convergence for the light rays that originate from a given object.
Non-contact thermography, is the field of thermography that derives diagnostic indications from infrared images of the human body. Nuclear medicine, uses administered radioactive substances to create images of internal organs and their function. Optical imaging, using light as an investigational tool for biological research and medical diagnosis

This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Biophotons may be detected with photomultipliers or by means of an ultra low noise CCD camera to produce an image, using an exposure time of typically 15 minutes for plant materials. [ 9 ] [ 3 ] Photomultiplier tubes have been used to measure biophoton emissions from fish eggs, [ 10 ] and some applications have measured biophotons from animals ...
Biochemistry, or biological chemistry, is the study of chemical processes within and relating to living organisms. [1] A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology, and metabolism.
Another example is that when many images of a model animal (e.g. C. elegans or Drosophila brain or a mouse brain) are collected, there is often a substantial need to register these images to compare their patterns (e.g. those correspond to the same or different neuron population, those share or differ in the gene expression, etc.).
Image from Andreas Vesalius's De humani corporis fabrica (1543), page 206. Historically, biological illustrations have been in use since the beginning of man's exploration and attempts to understand the world around him. The paleolithic cave paintings were so detailed that we can even recognize species and breeds of many of the depicted animals ...
