Looking through medical imaging
The main purpose of this unit is to help you understand how we can use different types of radiation and other technologies to obtain information about the internal structures of objects or organisms that are not transparent to visible light.
When we have the ability to see into objects, it gives information that can be used to guide other choices – from determining the safety of a bridge (looking for microfractures in beams), to the integrity of a jet turbine or airscrew (checking to see for weaknesses that may result in catastrophic failure) or to diagnose medical conditions prior to surgery.
Your task for this unit is to select one of the following medical physics technology, and explain the basic physics behind what form of energy is used (define the type), how it is generated (if appropriate), how it interacts with material objects (how it is affected by passing through matter), how it is received (how the energy is collected and transformed so that the internal structure of what it passed through is made visible). You also need to discuss the advantages (what it allows the user to do) and disadvantages (what risks or dangers are inherent in the used of the technology).
Here are the list of available technologies.
- CT scans
- PET scans
- MRI scans
- Nuclear Imaging
- Radiation Therapy
- Laser treatment
This is a matter of first come, first served, so post your selection in the comments below. Everyone must select a different technology. Here is a link to the project sheet, which also includes the marking criteria (Medical Physics Presentation Sheet 2013).
You are required to provide an online response to this, and some level of interactivity is expected. The best option for this is to develop a simple web page, perhaps through Wix. Youtube is an obvious choice (take advantage of annotations linking to other resources for interactivity), but something like Digital Films or Wideo or Voki or Screencast-o-matic would offer other technology.
