1 McGill University Medical Physics Unit Radiotherapy Lab: MDPH 603 (2 credits) Winter 2017 Coordinators: Marija Popovic, Steve Davis Office hours: Monday 15:00-16:00, DS1.5116, McGill University Health Centre (Glen site), x44160 Grading: Lab reports: 75% Final exam: 25% Pass mark is 65%. In the event of extraordinary circumstances beyond the University s control, the content and/or evaluation scheme in this course is subject to change. Lab format: Students will be assigned to groups, and will follow the attached lab schedule. Dates and times are subject to change depending upon machine availability. Labs will not be repeated. Please remember that the rooms and instruments are also used to treat patients, many of whom have compromised immune systems. Please keep the rooms clean, tidy and germ-free. Prepare for your lab by reading up on the subject. Bring a notebook with fixed, numbered pages and calculator to note down measurements and experimental setup descriptions. Report instructions and format: Reports are to be ed in PDF format to Marija and Steve within two weeks after that lab. Late reports will not be accepted. Each student will prepare his or her own lab report, and all labs have an individual report. Except for the measurement data, which is common to the group, all written text in the report must show individual comprehension of the material covered. Raw measurement data must be included in the main body of the report or in an appendix. Copying and plagiarism will not be tolerated, and references should be used.

2 McGill University values academic integrity. Therefore, all students must understand the meaning and consequences of cheating, plagiarism and other academic offences under the Code of Student Conduct and Disciplinary Procedures(see for more information). In accord with McGill University s Charter of Students Rights, students in this course have the right to submit in English or in French any written work that is to be graded. In a similar way to published papers or a thesis, the report should contain the following sections: Introduction, Methods and Materials, Results, Discussion, Conclusion, and References. Reports should also answer all questions and tasks provided in each lab outline. The reports will be prepared on a computer and printed single-sided. Complex figures can be hand-drawn but must be legible. The lab report should be written in the form of a paper as if it were to be submitted for a peer-reviewed journal. This consists of: 1. Introduction Describe the context and the purpose of the lab/theme. Describe how your work fits in the complete picture of clinical radiation physics. 2. Methods and Materials Describe all hardware, software, equipment and procedures used for the work. Be very specific in this. Someone reading this must be able to reproduce what you have done. 3. Results Describe the results of the measurements and calculations done. Limit this to describing the results with little or no interpretation except when necessary for the flow of the paper or when the Results section is combined with the Discussion section (see below). 4. Discussion

3 Discuss the results, describe anomalies, discuss the questions posed in the lab instructions or during the lab. Sometimes, when appropriate, this section is combined with Results to form Results and Discussion. 5. Conclusion Draw main conclusions of the lab and work that is needed to clarify any unresolved issues. 6. References Present all literature cited; use Harvard-style referencing (see, e.g., 7. Appendix (if necessary) Raw measurement data from the laboratory presented in an organized manner. Each report will be around 6-7 pages (unless otherwise specified by the lab instructor), excluding cover page, tables, graphs and figures, references, and appendix. Each report will use 1.5 line spacing, 12 pt font size, Times New Roman font (such as this text is written, or similar acceptable font), and have 2.5 cm (or 1 inch) margins all around.
