EE210220 Bio Medical Instrumentation L-T-P-Cr: 3-0-0-3
Objectives:
1. With widespread use and requirements of medical instruments, this course gives knowledge of the principle of
operation and design of biomedical instruments.
2. It attempts to render a broad and modern account of biomedical instruments.
3. It gives the introductory idea about human physiology system which is very important with respect to the
design considerations.
4. It gives an idea about the application of instruments in the diagnostics and therapeutic area.
Pre-requisites: None
Outcome:Upon completion of the course, the student will be able to:
1. Possess a clear knowledge about human physiology.
2. Know the principle of operation and design of different biomedical sensors and instruments.
3. Understand specific applications of biomedical engineering and measurement techniques.
4. An idea about the application of instruments in the diagnostics and therapeutic area.
