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 nine labs, quizzes, a practical exam, and a project. 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 2g.
Assignments may be turned in up to three days late for 1/2 credit.
Labs
Students will work in teams of two to complete eight labs. Each lab is preceded by a pre-lab assignment. Each group will turn in one prelab assignment and one report after lab. Prelabs are due the day before lab at 10:30am in the Bioengineering department office.
Each pre-lab assignment is worth 1 point. Each lab report is worth 10 points. Thus, labs are worth 88 points in total.
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.
Practical exam
Students will take a lab practical exam. Without their lab partner, students will be expected to build some circuits and take measurements from them. The lab practical is worth 30 points.
Project
Lab groups will spend two lab periods working on a design project. During their last lab period, students will present their project to the TA and instructor. Each lab group will turn in a written report due on the last day of class. In total, the project is worth 30 points.
Quizzes
Quizzes will be worth 20 points in total. Only one take-home quiz is scheduled at the beginning of the semester (the safety quiz). Other quizzes will be unannounced, occur at the start of class, and cover the lab to be covered in that day's lecture.
