Description
Introduction to engineering aspects of the detection, acquisition, processing, and display of signals from living systems; biomedical sensors for measurements of biopotentials, ions and gases in aqueous solution, force, displacement, blood pressure, blood flow, heart sounds, respiration, and temperature; therapeutic and prosthetic devices; medical imaging instrumentation. Same as ECE 414. Prerequisite: ECE 205 or ECE 210.
Course Objectives
- Understand the limitations of instrumentation in terms of accuracy, resolution, precision, and reliability (l,m).
- Analyze and design operational amplifier and instrumentation amplifier circuits to amplify biosignals (a,b,c,d).
- Analyze and design filter circuits to filter unwanted signals from biosignals (a,b,c,d).
- Understand the origin of cardiac and muscle biosignals and how they are acquired using ECG and electromyogram electrodes (a,c,d,e,k,m).
- Understand electrode circuit models and how they effect signal acquisition (a,c,e,m).
- Understand they physical modes of operation of various biosensors (amperometric, enzymatic, optical, resistive, capacitive) (a,k).
- Describe and compare methods and instrumentation needed to measure pressure and flow in the body (a,e).
- Determine and characterize the factors that limit medical 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 a project (d,f,g).
- Present work in both written and oral reports (f,g).
Required Textbook
"Medical Instrumentation: Application and Design, Fourth Edition," John Webster, Editor, published by Wiley 2009. This is the latest edition of the book with the blue and brown cover. Changes from the Third Edition are minimal, but end-of-chapter problems have different numbers. Students who use the Third Edition are advised to check the Fourth Edition before starting homework assignments.
Grading
Student grades will be based on 5 homework sets (5% each), two midterm exams (25% each), and a final project (25%). 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.
Homework
Homework problems will be taken from the textbook or based on journal articles. Students can work with a partner and turn in only one assignment - be sure that both students' names are included. Homework will be accepted up to three days late for half credit.
Exams
Each exam will cover approximately one-half of the lecture material. Exam scores may be curved.
Final Projects
For the final project, student teams will investigate one medical instrument. Teams will use journal articles, textbooks, patents, and company websites to learn more about it. They must also interview a user of the instrument and observe it being used. Grades will be based on an online report. More information on the project will be presented in class.
