Course description and aims
The purpose of this course is to understand the radiation therapy techniques through the practice. It starts from the first step of radiation therapy treatment planning CT process and followed by treatment planning and output measurements of linear accelerator. Finally, dosimetry using radiophotoluminescent glass dosimeter is included in order to understand the recent trend of QA/QC activity in radiotherapy.
Medicine and physics could be regarded distant to each other, however, should be intimate. For example, in order to run safely and update intensively the modern therapy techniques, there is a strong growing demand for the commitment by the medical physicists with higher educational level knowledge in physics. This course can be considered as a case study how to apply physical knowledge to the real clinical situation. We are pleased to offer the opportunity to perform real treatment planning and dosimetry.
Student learning outcomes
By the end of this course, students will be able to:
1) Explain the physical meaning of CT value.
2) Explain the necessity of CT value conversion to stopping power ratio.
3) Understand the strategies and methods to create treatment plan.
4) Acquire the basic skill of dosimeter calibration and dosimetry of linear accelerator outputs.
5) Understand the methodology of dose evaluation using radiophotoluminescent glass dosimeter.
Keywords
radiation therapy, particle radiotherapy, CT value, stopping power ratio, treatment planning, radiation dosimetry, absorbed dose, QA/QC
Competencies that will be developed
| ✔ Specialist skills | Intercultural skills | Communication skills | Critical thinking skills | ✔ Practical and/or problem-solving skills |
Class flow
At the beginning of each class, introduction and theory of practice are given. After the introduction, practice starts with teacher guide using clinically used medical modalities. To prepare for class, students should read the course schedule section and check what topics will be covered. Required learning should be completed outside of the classroom for preparation and review purposes.
