Study Notes
What is Biomedical Engineering?
- Biomedical Engineering encompasses a broad range of applications, from biosensors and instrumentation to artificial organs and medical imaging.
- Biosensors and biomedical instrumentation: Focuses on detecting, measuring, and monitoring physiological signals.
- Signal processing: Analyzes and interprets bioelectric data for diagnostic purposes.
- Artificial organs: Develops devices to replace bodily functions.
- Medical informatics and artificial intelligence: Utilizes computer analysis of patient data for clinical decision making.
- Medical imaging: Creates graphical representations of anatomical details and physiological function.
- Biotechnology and tissue engineering: Involves the creation of new biological products.
Roles of Biomedical Engineers
- Biomedical engineers play a crucial role in research, development, and application of biomedical technology.
- They are responsible for developing materials for implanted organs, designing diagnostic instruments, analyzing medical data, ensuring product safety, designing imaging systems, creating patient monitoring systems, crafting biomedical sensors, and developing disease diagnosis and treatment systems.
- They also work to model physiological systems, design communication aids for disabled individuals, and study the mechanics of the human body.
Example - Study of Cardiac Function
- Biomedical engineers can develop mathematical models to explore fluid flow through the human heart.
- These models help understand complex dynamics and create simulations to test and refine the model.
- Simulations are used to:
- Understand complex features.
- Design experiments on actual biological systems.
- Amend the model based on experimental results.
- Predict the effect of changes on a biological system.
Evolution of the Health Care System
- Before 1900, illnesses unsolvable by home remedies were often fatal.
- The 20th century marked significant advances in the basic sciences, leading to advancements in medical technology.
- Key milestones include:
- 1903: First electrocardiograph.
- 1930s: X-ray visualization of all organ systems, development of hematology.
- 1950s: Electron microscope, PET scans, increased use of electronics in healthcare.
- After WWII: Focus on rehabilitation engineering, prosthetics, and the first successful kidney transplant.
- 1970s: Development of CT and MRI, functional MRI.
- 21st century: Robotics in surgery.
Recent Advances
