Paper/Project: 

The objective of this task is to develop a measurement protocol of a clinical/dosimetric interest. Start with identifying a project/problem by searching an electronic publication database available through the University of Toledo library or other on-line resources such as ScienceDirect . Examples of relevant publications can be found on the Z drive (Z:\RadiationOncology\Common\Education materials\RD-II papers\). Next, briefly discuss a topic of your interest with me through email or in person to finalize the proposal. Project proposal should be completed by March 15th.

For the implementation part, you are expected to compose a protocol (using MS Word or similar software), consisting of the following sections:
1. Problem statement
2. General approach
3. Required equipment
4. Step-by-step measurements/procedure instructions
5. Expected results, with any relevant equations, graphs, etc.
6. References

Alternatively, you can create a spreadsheet (using MS Excel or similar) with detailed instructions on how to perform measurements. If you follow this path you could use an existing published protocol, e.g., one of the TG protocols (has to be sufficiently different from any of the spreadsheets used in our clinic). The deadline for the project is May 3rd.
