Glossary of Terms
- Changing the function of a cell using chemical, protein or even mechanical force. Most commonly, a cell, like a skin cell, may be treated with protein factors that reprogram it to become a stem cell that can then be reprogrammed, with various protein or chemical factors, to function as a different type of cell such as a liver, heart or nerve cell.
- The amount of a chemical changes over a specified distance, generally increasing from a lower to higher amount. The gradual increase in the amount of a chemical drives many processes in our body that allow cell growth.
- An interactive software-based system designed to assist physicians and other health professionals as well as patients with diagnostic and treatment decisions and reminders. The system compiles and analyzes medical information from raw data, health observations, and other medical information sources.
- The use of mathematics, statistics, physics and computer science to study the mechanism and behavior of complex systems by computer simulation. A computational model contains numerous variables that characterize the system being studied. Simulation is done by adjusting these variables and observing how the changes affect the outcomes predicted by the model.
- A computerized X-ray imaging procedure in which a narrow beam of X-rays is aimed at a patient and quickly rotated around the body, producing signals that are processed by the machine’s computer to generate cross-sectional images—or “slices”—of the body. These slices are called tomographic images and contain more detailed information about the internal organs than conventional X-rays.
- A substance used to enhance the imaged appearance of structures, processes or fluids within the body in biomedical imaging.
