Summary
A new continuous line scanning system (CLSS) for prostate cancer treatment was developed. This system precisely delivers radiation doses, meeting clinical requirements for effective cancer therapy.
Area of Science:
- Medical Physics
- Radiation Oncology
Background:
- Proton therapy offers precise radiation delivery for cancer treatment.
- Advanced beam delivery systems are crucial for optimizing dose distribution.
Purpose of the Study:
- To develop a continuous line scanning system (CLSS) prototype for prostate cancer treatment.
- To leverage the high-intensity, continuous proton beam from the cyclotron at the National Cancer Center Hospital East.
Main Methods:
- The CLSS modulates dose distribution by adjusting scanning speed at different beam energies.
- A beam-intensity control and rapid on/off switching system maintain constant beam intensity.
- A beam alignment system enhances positional accuracy, and a scanning control system manages patterns and data acquisition.
Main Results:
- The CLSS demonstrated beam size, position, intensity, and scanning speed within clinical requirements.
- The system achieved accurate 3-dimensional dose distribution suitable for clinical treatment planning.
Conclusions:
- The developed CLSS meets clinical performance standards for prostate cancer treatment.
- The system has been in clinical use for prostate cancer therapy since October 2015.
