Main Fields of Biomedical Engineering
37
Medical Instrumentation:
Medical instrumentation is the application of electronics and measurement techniques to develop devices used in diagnosis and treatment of disease. Computers are an important and increasingly essential part of medical instrumentation, from the microprocessor in a single-purpose instrument to the microcomputer needed to process the large amount of information in a medical imaging system. Examples of medical instrumentation include: heart monitors, microelectrodes, defibrillators and glucose monitoring machines
38
Biomaterials Biomaterials is the use of materials, both living tissue and artificial materials, for implantation. Understanding the properties of the living materials is vital in the design of implant materials. The selection of an appropriate material to place in the human body may be one of the most difficult tasks faced by the biomedical engineer. Certain metal alloys, ceramics, polymers and composites have been used as implant materials.
39
Biomaterials (cont) Biomaterials must be
nontoxic, non-carcinogenic, chemically inert (not reacting violently with the body's chemical composition), Stable mechanically strong enough to withstand the repeated forces of a lifetime of use. Newer biomaterials even incorporate living cells in order to provide a true biological and mechanical match for the living tissue.
40
Biomaterials (cont) Examples of biomaterials include Dental adhesives,
Bone cement, Replacement bones/joints, Heart prosthetics, Heart replacement valves Artificial lungs Artificial kidneys.
41
System Physiology and Modeling
The use of scientific and engineering principles to predict the behavior of a system of interests. Systems of interest may include the human body, particular organs or organ systems and medical devices.
42
System Physiology and Modeling (cont)
Modeling is used in the analysis of experimental data and in formulating mathematical descriptions of physiological events. In research, modeling is used as a predictive tool in designing new experiments to refine our knowledge. Examples are the biochemistry of metabolism and the control of limb movements
43
Signal processing Collection and analysis of data from patients or experiments in an effort to understand and identify individual components of the data set or signal. The manipulation and dissection of the data or signal provides the physician and experimenter with vital information on the condition of the patient or the status of the experiment. Biomedical Engineers apply signal-processing methods to the design of medical devices that monitor and diagnose certain conditions in the human body. Examples include heart arrhythmia detection software and brain activity
44
Medical Imaging Medical Imaging combines knowledge of a unique physical phenomenon (sound, radiation, magnetism etc.) with high-speed electronic data processing, analysis and display to generate an image. Often, these images can be obtained with minimal or completely non-invasive procedures, making them less painful and more readily repeatable than invasive techniques. Examples include Magnetic Resonance Imaging (MRI), ultrasound and computed tomography (CT).
45
Biomechanics Biomechanics applies both fluid mechanics and transport phenomena to biological and medical issues. It includes the study of motion, material deformation, flow within the body, as well as devices, and transport phenomena in the body, such as transport of chemical constituents across biological and synthetic media and membranes. Efforts in biomechanics have developed the artificial heart, replacement heart valves and the hip replacement.
