Abstract:
Objective: High Intensity Focused Ultrasound (HIFU) is classified as the third category medical instruments, which means it require much more attention on its safety to patient. Methods: To achieve this goal, a safety monitor system was applied on “High Intensity Focused Ultrasound therapeutic equipment for Shallow tissue”. To design parallel port-based safety monitor method for high intensity focused ultrasound therapeutic system and make the bidirectional data flow. Results: By using parallel computation of FPGA, the safety monitor independently monitor several modules of the “Ultrasound therapeutic equipment”, and handles mal-function. A new EPP-Parallel port basic intelligent watchdog was introducing to monitor PC working state. Conclusion: The safety monitor system enhances the safety and reliability of the equipment, and provides helpful information for malfunction diagnose.
