10

The key areas of biomedical engineering are:

Bioinformatics

Bioinformatics involves developing and using computer tools to collect and analyze data related to medicine and biology.

BioMEMS

Bio Micro-electromechanical systems (MEMS) are the integration of mechanical elements, sensors, actuators, and electronics on a silicon chip. For examples: development of micro-robots to perform surgery inside the body, and a device that could be implanted inside the body to deliver drugs on the body's demand.

11

BiomaterialsBiomaterials are substances that are engineered for use in devices or implants that must interact with living tissue.

Example:Coatings that fight infection common in artificial joint implants.Coatings that fight infection common in artificial joint implants.

BiomechanicsBiomechanics is the mechanics applied to biology. This includes the study of motion, material deformation, and fluid flow.

Examples: Fluid dynamics involved in blood circulation and the development of artificial hearts.

12

Biotechnology

Biotechnology is a set of powerful tools that employs living organisms (or parts of organisms) to make or modify products, improve plants or animals, or develop micro-organisms for specific usage. micro-organisms for specific usage.

For examples:

The earliest efforts in biotechnology involved traditional animal and plant breeding techniques, and the use of yeast in making bread, beer, wine and cheese.

13

Neural Systems and Engineering

This emerging interdisciplinary field involves study of the brain and nervous system and encompasses areas such as the replacement or restoration of lost sensory and motor abilities, for example, retinal implants to and motor abilities, for example, retinal implants to partially restore sight.

Electrical stimulation of paralyzed muscles to assist a person in standing.

Robot arms that are controlled by signals from the motor cortex in the brain.

14

Physiological Systems Modeling

Many recently improved medical diagnostic techniques and therapeutic innovations have been a result of physiological systems been a result of physiological systems modeling. In this field, models of physiological processes (e.g. the control of limb movements, the biochemistry of metabolism) are developed to gain a better understanding of the function of living organisms.

15

Clinical Engineering

Clinical Engineers support and advancepatients’ care by applying engineering andmanagerial skills to healthcare technology.managerial skills to healthcare technology.

Clinical engineers can be based in hospitals,where responsibilities can include managingthe hospitals’ medical equipment systems forsafety and effectiveness.

16

Genomics

Genomics is a new discipline that involves the mapping, sequencing, and analyzing of mapping, sequencing, and analyzing of genomes - the set of all the DNA in an organism.

A full understanding of how genes function in normal and/or diseased states can lead to improved detection, diagnosis, and treatment of disease.

17

Micro and Nanotechnology

These fields include the development of microscopic force sensors that can identify changing tissue properties as a way to help changing tissue properties as a way to help surgeons remove only unhealthy tissue, e.g. using nanometer length cantilever beams that bend with cardiac protein levels in ways that can help doctors in the early and rapid diagnosis of heart attacks.

18

Rehabilitation Engineering This is the application of science and technology to

improve the quality of life for people with disabilities. This can include designing augmentative and alternative communication systems for people who alternative communication systems for people who cannot communicate in traditional ways, making computers more accessible for people with disabilities, developing new materials and designs for wheelchairs, and making prosthetic legs for runners in the Paralympics.

19

ERGONOMICS

Ergonomics, is the engineering science concerned with the physical and psychological relationship between machines and the people who use them.

The field of ergonomics is also sometimes called human or human-factors engineering, engineering psychology, and biotechnology.

20

Robotics in Surgery

Robotics in surgery includes the use of robotic and image processing systems to interactively assist a medical team both in planning and executing a surgery. medical team both in planning and executing a surgery.

These new techniques can minimize the side effects of surgery by providing smaller incisions, less trauma, and more precision, while also decreasing costs.

21

RadiologyIt refers to the use of radioactive substances such as x-ray, magnetic fields as in magnetic resonance imaging, and ultrasound to create resonance imaging, and ultrasound to create images of the body, its organs and structures. These images can be used in the diagnosis and treatment of disease, as well as to guide doctors in image-guided surgery

22

Nuclear Medicine

Nuclear medicine scans the detected radiation coming from a radiopharmaceutical that is inside a patient’s body. In contrast, other imaging procedures (such as X-ray and CT scan) obtain images by using devices that send CT scan) obtain images by using devices that send radiation through the body.

Nuclear medicine is also different from other imaging procedures in that it determines the presence of disease based on biological changes in tissue rather than changes in anatomy.

23

Radiotherapy

Radiotherapy treatment of a patient requires an individual planning, which includes mainly two individual planning, which includes mainly two areas: the medical and physical treatment planning taking into account of radiobiological aspects that; all body cells can be damaged or killed by radiation, but tumor cells are more sensitive to radiation than normal cells.

24

Radiotherapy equipment such as Linear Accelerator (LINAC) uses this principle to damage beyond repair; or kills the abnormal cancer cells in a tumor.

This equipment is used in successful radiation therapy to deliver a dose of radiation to the tumor while ensuring minimum radiation to the normal tissue.
