Description
Laboratory to accompany BIOE 414. The goal of the course is to provide students with laboratory experience to test the principles, design, and applications of medical instrumentation. This course also provides exposure to clinical applications of medical instrumentation. Same as ECE 415. Prerequisite: Credit or concurrent registration in BIOE 414.
Course Objectives
- Analyze, design, and construct operational amplifier and instrumentation amplifier circuits to amplify biosignals (a,b,c,d).
- Analyze, design, and construct filter circuits to filter unwanted signals from biosignals (a,b,c,d).
- Acquire electrical and biological signals by implementing virtual instruments with Agilent VEE, LabView, or amplifiers coupled to a computer with other software (b,c,d,k,m).
- Understand biosensor and electrode design and apply them for signal acquisition (a,c,e,m).
- Understand the limitations of instrumentation in terms of accuracy, resolution, precision, and reliability (l,m).
- Understand the origin of cardiac and muscle biosignals and acquire data using ECG and electromyogram electrodes (a,c,d,e,k,m).
- Determine and characterize the factors that limit ultrasound and other imaging methods in biological tissue (b,m).
- Describe the requirements and limitations of bioinstrumentation in the clinical environment (f,h,i,j).
- Function and interact cooperatively and efficiently as a team member in completing laboratory projects (d,f,g).
- Present laboratory data in a written format (f,g).
Required Textbook
There is no required textbook. All lab procedures will be available from this website in PDF format. Students may find "Medical Instrumentation: Application and Design" to be a useful reference.
Grading
Student grades will be based on twelve labs, a safety quiz, a practical exam, and a final exam. The following grading scale will apply (>97% A+, >93-97% A, >90-93% A-, >87-90% B+, >83-87% B, >80-83% B-, >77-80% C+, >73-77% C, >70-73% C-, >67-70% D+, >63-67% D, >60-63% D-, 0-60% F). Grades will be maintained on Illinois Compass.
Labs
Students will do eleven labs and turn in a report detailing their findings and answering questions. Each lab has a pre-lab assignment. In total, labs determine 55% of the course grade. Teaching assistants will give due dates for pre-lab assignments and reports, but in general pre-labs are due a few days before lab and reports are due a week after the lab.
Making up labs: Students who know that they will be missing their lab section must contact the course TAs to arrange attendance at a different section. If this is not possible, students can make up the lab during the following week. Students must contact the TAs ahead of time and not simply show up at a different section.
Safety quiz
The Safety Quiz will be based on information in NIOSH's Electrical Safety: Safety and Health for Electrical Trades Student Manual. The Safety Quiz will be worth 10% of the final grade.
Practical exam
Students will take a lab practical exam mid-semester. Without their lab partner, students will be expected to build some circuits and take measurements from them. The practical exam will be worth 15% of the final grade.
Final exam
The final exam will be open note, will cover the entire course, and will be worth 20% of the final grade.
