Course description

This course introduces the nonscientist to technologies important to modern medicine, and the basic physical and physiological principles which underlie them. Readings in a text prepared especially for this course, the popular scientific literature, and medical texts will treat both the scientific basis and societal implications of laparoscopic surgery, laser surgery, photodynamic therapy, ultrasound imaging, x-ray and radionuclide imaging, computer tomography (CAT or CT scans), positron emission tomography (PET scans), radiation therapy and magnetic resonance imaging (MRI). Specific medical applications discussed will include (but are not limited to): colon cancer screening, arthroscopic knee surgery, laser eye surgery, dermatological laser surgery, obstetrical ultrasound, cardiovascular ultrasound, mammography, osteoporosis screening, cancer radiation therapy, and applications of PET and MRI brain scans in neuroscience.

Enrollment Limits/Who should take this course: This course is limited to an enrollment of 40. Preference is given to students not already majoring in the natural sciences. Natural science majors may take it as an elective, although they should consult with the instructor before doing so.

Prerequisites: None. Only precalculus-level mathematics will be used.

Textbook & Readings

The main text for the course is Introduction to Physics in Modern Medicine, by Suzanne Amador Kane, Taylor and Francis Publishers, 2003, available at the Haverford Bookstore. Reserve copies are available in White Science and Collier Libraries. Additional reserve readings can be found in the KINSC Science Library.

Class meeting times and location

There will be three one hour lectures every week, MWF 10:30-11:30 in KINSC H108.

You are welcome to attend Physics Clinic every Wednesday and Thursday night 7-10pm in KINSC H107 (the Physics Lounge) to get help with the homework.

You are expected to attend all class meetings and you are responsible for any missed material or announcements. Absences due to athletics, interviews, etc. should be preceded by an email to the instructor to set up a makeup assignment. More than two absences for reasons other than illness per semester would be considered excessive, and may be considered in grading.

Course Requirements

Homework assignments will be distributed roughly every two weeks in class, and due one week later at the beginning of class. See the syllabus below for more details. There will be one take-home midterm exam and a self-scheduled final exam. The homework assignments and exams will contain a combination of short quantitative problem-solving and essay-style questions. There will be one poster session as well (see details below).

Exams must be completed and turned in by the announced deadline unless special arrangements have been made in advance with the instructor, or unless you obtain a Dean's excuse.

Poster Session

There will be one poster session assigned this semester. This presentation will address the topics covered in the course from a perspective chosen by the student in cooperation with the instructor. For the poster presentation, students may work in teams of two people. For example, a student might elect to do a presentation discussing the economic consequences of laparoscopic surgery, an overview of government regulation of the medical instrumentation industry, political issues surrounding access to various medical diagnostic procedures, a discussion of social issues surrounding mammography, or safety concerns surrounding radiation. The expected level and tone is that of a journalist writing a newspaper or news magazine article, although a full bibliography and careful citation of sources is required. The poster session will be described in more detail in class.

Grading

In determining the course grade, the following weighting will be used:

• Exams 35% (Midterm: 15%;Final 20%)
• Poster Session 20%
• Homework 45%

You will be able to view your relative standing and approximate grade throughout the semester.

Late Assignment Policy

You may turn in two homework assignments up to one week late with no penalty. (Save these freebie lates for when you need them!)

Thereafter, late assignments will be graded according to the following formula:
Up to one week late: 75%
Up to two weeks late: 50%

Assignments will be graded up to one month after the due date.

Honor Code Issues

The instructor values Haverford's honor code for the integrity it fosters and the pedagogical flexibility it affords.  I expect your cooperation in respecting the following guidelines.  Please request clarification whenever necessary.

• You may seek assistance from the instructor,ask for help from Physics Clinic TA's, consult other written sources, and work with your fellow students in doing the homework problems.  However, you must write up your own solutions. In particular, direct copying of other solutions, either from other student's, the web, paper sources or from a black/whiteboard, DOES constitute a violation of the Honor Code.
• Solutions to the written exercises will be made available shortly after the assignments are due.  If you are doing a late set, after one week past the due date you may consult the solutions, but you may not copy them.  However, I strongly encourage you to give the problems an honest effort on your own first, so as to learn from them most effectively. Copying a solutions set slavishly IS a violation of the Honor Code.
• You should work alone on the take-home exam.  You are expected to follow all other instructions given on the exams.
• Extensions on taking Exams can only be granted with a Dean's excuse.

Accommodations:

Students who think they may need accommodations in this course because of the impact of a disability are encouraged to meet with the instructor privately early in the semester.  Students should also contact Rick Webb, Coordinator, Office of Disabilities Services (rwebb@haverford.edu, 610-896-1290) to verify their eligibility for reasonable accommodations as soon as possible.  Early contact will help to avoid unnecessary inconvenience and delays.

Resources

List of Possible Poster Topics

The Internet is a valuable and up-to-date resource for information about medical physics, and we will make extensive use of it throughout the semester. This section will contain listings of relevant internet resources for each section of the course. The following were chosen more for their interest to general audiences than for completeness. Let your instructor know of interesting and useful sites you find on your own!

FDA Center for Devices and Radiological Health is a good starting place for examining issues relating to medical device safety and regulation.
