GS02-1093 - Introduction to Medical Physics I
Basic Interactions

Schedule - Fall 2014

last revised 10/29/2014

Objectives:

The purpose of this course is to provide the medical physics student with an introduction to ionizing radiation and its use in medicine. Topics covered include production of radiation, interactions of radiation with matter, and measurement of radiation. This course is a prerequisite for subsequent courses in medical physics.

Lectures:

Mondays, Wednesdays, and occasional Fridays 2:30 - 3:30 pm
Imaging Physics Classroom (FCT14.5059)

Problem Sessions:

Thursdays 2:30 - 3:30 pm
Imaging Physics Classroom (FCT14.5059)

Required texts:

The required text for the course is The Physics of Radiology, 4th edition, by H.E. Johns and J.R. Cunningham [link]. A discussion of texts for this course can be found in a handout written by Dr Willliam Hanson for a previous incarnation of this course. [link]

Problem Sections:

On Thursdays, we shall go over problems. These sessions will be jointly run by Drs Melancon and Nishino.

Grading:

Grading will be based on the following formula:

40% - in-class quizzes
40% - final examination
10% - classroom participation
10% - homework

The need for care:

Medical physics is a discipline in which care and meticulousness is essential, with dire consequences for sloppy work. In order to provide you with some feel for the consequences that may arise when one is not careful, the following link is provided. Please view these presentations at your earliest convenience. [link] In addition a series of articles in the New York Times is a resource for finding out about what can go wrong with radiation. [link]

Before each class:

In order to make most effective use of class time, it is essential for you to come to class prepared to discuss the class material. Before class begins, please download the lecture notes and listen to the recorded class lecture. In addition, please read the reading assignment. Before 9 am the day of each class you are to take the online pre-test. The pre-test should be relatively easy and is just to ascertain whether or not you have prepared for class on that day. It is an open-book, open-notes examination. Be sure to include your name on the pre-test so you can get credit for doing it. Doing and submitting the pre-tests will count toward your classroom participation credit.

During class:

This class is going to be somewhat different from most classes you have experienced previously. It is taught using a method called "Peer Instruction," developed by Dr Eric Mazur, a physics professor at Harvard University. Using this technique, I present a multiple-choice question to the class. The question generally illustrates a concept presented in the lecture. Hence it is called a "ConcepTest question." You will have a few minutes to determine the answer to the question. Generally the answer to a ConcepTest question will require neither memorization of facts nor extensive computation, but rather understanding of a concept. When you have determined the answer, you will hold up a card with the correct answer (A, B, C, or D) in such a way that only I can see your answer. Everybody must vote for an answer, even if you have to guess. If everyone has the correct answer, we will briefly discuss the answer, and then we will go on to the next concept. More often than not, some of you will understand the concept and get the correct answer, while others will not have the correct answer. When this occurs, you will gather into groups of 4-5, and each one of you will be charged with convincing the others in the group that your answer is correct. After several minutes of disciussion, you will be asked to vote again on the correct answer. We will then discuss the answer and the concept that has been presented. Participation in these discussions will count toward classroom participation credit.

Follow this link to see an example of a ConcepTest question (in another branch of physics): [link to ConcepTest question]

After each class, the ConcepTest questions for that class will be posted on the website.

If you are interested in finding out more about Peer Instruction, here is a link to a YouTube video of a presentation given by Dr Mazur: [link to Peer Instruction presentation]

End of class:

At the end of class, you will be asked to answer a short questionnaire that asks you to identify the key points of the class and any points that remain unclear. Be sure to bring a WiFi-enabled mobile device (smart phone,iPad, laptop) to class, as the questionnaire is online. If you don't have such a device or forget to bring it to class, I can provide hardcopy versions of the questionnaire. The questionnaire is to be completed before you leave the classroom.

At some point after class, hopefully immediately, but more likely a few hours later, I will post your unclear points on Facebook (see below). These questions will be posted under my name, so you need not be embarrassed if you do not understand something and wish to have a point clarified. Other students in the class will have 24 hours after posting to respond to your questions. If you provide a good response, you will receive additional classroom participation credit towards your final grade. After 24 hours, if a resonable response has not been posted, I will post a response.

To access WiFi in the classroom, you might try uthsc-guest or mdaguest.

After each class:

Most lessons are associated with problem sets. These problem sets will be due at 4 pm one week after assignment. They may either be emailed to me, handed in during class on the day they are due, or placed in my mailbox after class. Solutions to problem sets will be posted after they are due. Problem sets will be graded, and the grades counted toward your final grade.

Guesstimation:

A skill important for medical physicists to possess is the ability to estimate an answer when you have no idea what the answer is. Many problem sessions will begin with a guesstimation problem. Follow this link to see an example of a guesstimation problem. [link]

Course Evaluation:

After the orientation lecture, I would like to know something about your expectations regarding this course. Please access this evaluation form [link] and fill it out. We may discuss your expectations in class.

Later in the semester, I would like to know how you perceive the course is coming along. Please access this second evaluation form [link] and fill it out.

At the end of the semester, you will be asked to fill out two evaluation forms. One is provided by the GSBS, and is filled out online, the other is provided by the course coordinator and is accessible from this link. Please access this evaluation form and fill it out at the end of the semester. This evaluation form was developed by your fellow students and goes into somewhat more detail than the GSBS form. It also asks for more in the way of free-form answers. Please take the time to fill this form out, as it will be very helpful to me to make this a better course.

Facebook:

A Facebook group has been set up to support communication in this course. Please go onto Facebook and request that I friend you. My email address is gstarksc@mdanderson.org. Once I have friended you, I will add you to the 2014 Med Phys I group.

I will be using Facebook to communicate information to you. Please use Facebook to ask questions regarding this course. Questions regarding course management will be answered when I see them. I will defer answering questions pertaining to course content to give your fellow students first shot at providing an answer. Correct answers to Facebook questions will be counted positively toward your final grade, i.e., you may gain extra credit, and they will also help your friends understand the course material.
