- Radiation Oncology
Background:
- Radiosurgery is a key treatment for intracranial lesions.
- Animal models are vital for advancing radiosurgery techniques.
- Developing precise tools for animal radiosurgery is essential.
Purpose of the Study:
- To create a versatile stereotactic device for rats.
- To enable radiosurgery using a Gamma Knife in animal models.
- To facilitate research for improved radiosurgery strategies.
Main Methods:
- Modified an existing stereotactic frame design for rat use.
- Adapted the device for Gamma Knife models B and C.
- Developed an auxiliary tool for precise target point alignment.
Main Results:
- Verified device reliability through radiation profile and dose analysis.
- Demonstrated the device's utility in experimental irradiations.
- Confirmed usefulness in both normal and tumor-bearing rats.
Conclusions:
