Part 1.

1. Why do you think IGRT may be a better way to check the delivery of radiation therapy? Explain IGRT.

2. Discuss the application and use of super?cial and orthovoltage treatment in radiation therapy. What energy ranges are used? What type of cancers are treated?

3. Why must a monthly calculation correction be made for the 6000 treatment? How is Cobalt different than external beam radiation therapy?

4. Discuss the major components of the linear accelerator, including the klystron, waveguide, circulator, electron gun, accelerator guide, and bending magnet. Explain what each component does.

5. Describe the difference between a beam-flattening filter and a scattering foil. Which is used for electrons and which for photons? What cancers do we treat with electrons? Why?

6. Describe the advantages of a treatment couch with 6 degrees of freedom. How is it different than a standard treatment couch?

Part 2.

Create a chart for DMAX for all beam energies from superficial to 25mv. Explain what dmax is and illustrate it going into a patients body based on the energy of the beam.
