If frequent medical supervision is required for safe treatment, then treatment safety is improved, but treatment cost and time consumption increase
Solution Approach 1:
The control unit continuously monitors treatment parameters including irradiation duration, intensity, and patient position, providing real-time feedback to ensure safety. The system can automatically adjust or terminate treatment based on monitored parameters, eliminating the need for frequent medical supervision while maintaining safety standards.
Solution Approach 2:
The device performs self-monitoring and self-regulation of treatment parameters, with the control unit autonomously managing irradiation delivery based on predefined safety thresholds and treatment protocols, freeing patients from the need for frequent medical visits.
3Ease of operation
If irradiation intensity and duration are not precisely controlled, then ease of operation is improved, but treatment effectiveness and safety deteriorate
Solution Approach 1:
The control unit continuously monitors irradiation delivery parameters and provides real-time feedback to maintain precise control.

The device allows dynamic adjustment of irradiation parameters during treatment based on real-time monitoring and patient response. The control unit can modify intensity and duration within safe limits to optimize treatment effectiveness while maintaining safety, providing both flexibility and precision.
4Ease of operation
If a simplified device is used for home treatment, then ease of operation and cost are improved, but treatment precision and safety deteriorate
Solution Approach 1:
The device is designed for patient self-administration with automated control of irradiation parameters. The control unit manages treatment delivery, monitors safety parameters, and can interrupt treatment if thresholds are exceeded, providing both ease of home use and safety through autonomous operation.
Solution Approach 2:
The control unit continuously monitors treatment parameters during home use and provides real-time feedback to ensure safety. The system tracks irradiation delivery and can automatically adjust or terminate treatment based on monitored parameters, maintaining safety standards even in unsupervised home environments.
