奈米磁粒腫瘤熱療是將磁性奈米粒子注射到腫瘤細胞中，並在體外以高週波加熱器提供交變磁場，使奈米磁粒升溫，達到殺死腫瘤細胞的效果。本研究目的在建立數位監控系統於高週波加熱器，使加熱參數數據化，有利於加熱實驗的控制及結果分析。本監控系統以德州儀器生產的數位控制晶片(TMS320F28235)為核心，輔以CPLD (EPM3256)和感測電路組成。此系統能在高週波加熱器運作過程中，即時傳回加熱器的輸出電壓，輸出電流和操作頻率等參數。經實驗結果證實可於加熱過程中量取頻率、電壓、電流等大小，轉為數值後，作為調整輸出的控制信號的依據，並在加熱器發生錯誤時即時做出反應，以保證其控制和安全性都能達到醫療設備的標準。

Tumor hyperthermia by magnetic nanoparticles (MNP) is a therapy method by injects magnetic nanoparticles to the tumor cells and provides alternative magnetic field using high frequency induction heating machine which induced heats on the nanoparticles to kill the tumor cells. The main goal of this thesis is to design a DSP-based digital monitoring system for electromagnetic heating machine. In this system, the critical heating parameters are acquired and converted to digital values which are conducive to the control of heating experiments and for further results analysis. The digital monitoring system utilizes a digital microcontroller (TI TMS320F28235) as the core, supplemented with CPLD (EPM3256) and sensing circuits. This system is designed to be operated during the thermotherapy and provides instant feedback signals, such as voltage, current, and frequency. The experimental results show that the system function properly via the control signals, and respond to errors in a timely fashion that fulfill the controllability and safety of medical equipments.
