Medical Imaging refers to the techniques and processes used to create images of the human body for clinical purposes.

Medical Imaging refers to the techniques and processes used to create images of the human body (or parts thereof) for clinical purposes (medical procedures seeking to reveal, diagnose or examine disease) or medical science (including the study of normal anatomy and function). It is a part of biological imaging and incorporates radiology, radiological sciences, endoscopy, thermography, medical photography and microscopy . Measurement and recording techniques which are not primarily designed to produce images, such as electroencephalography (EEG) and magnetoencephalography (MEG) and others, but which produce data susceptible to be represented as maps (i.e. containing positional information), can be seen as forms of medical imaging. In scientific investigation, medical imaging constitutes a sub-discipline of biomedical engineering, medical physics or medicine. Medical imaging is that the properties of living tissue. In the case of ultrasonography the probe consists of ultrasonic pressure waves and echoes inside the tissue show the internal structure. In the case of projection radiography, the probe is X-ray radiation which is absorbed at different rates in different tissue types such as bone, muscle and fat.

Medical labels are suited to medical/biological research applications where data integrity is critical. The label is unaffected by extremes in temperature and is protected from chemical agents commonly used in laboratory settings. The adhesive is suitable for use in food packaging and for blood bag identification due to the absence of tacking agents that migrate through most substrates.

Medical Lasers affect human tissue by transferring radiant energy to the target cells. The radiant energy turns into heat when the cells absorb it. As the target cells are heated, all their proteins are destroyed and their internal pressure rises rapidly. The cells then explode, giving off smoke-like steam called a laser plume. The major effects of most lasers on tissue are coagulation of blood and protein, and vaporization. Vaporization is the removal of tissue through its conversion from a solid to a gas.In general, there are two types of medical laser systems, contact and non-contact. Contact systems work by sending laser light through a fiber or sapphire crystal tip. The tip absorbs the radiant energy and becomes hot. Direct contact between the tissue and the heated tip causes conduction of the heat energy from the tip to the tissue, resulting in the vaporization of the target cells. In contrast, non-contact laser systems do not directly touch the tissue. Instead, the laser light transfers radiant energy to the tissue. Heat results when the cell absorbs the radiant energy and the molecules in the tissue begin to move. In both types of system, the laser light itself is not hot. Heat is created only after the laser's radiant energy is absorbed, either by the tip or by the tissue.
