| 摘 要： | 设计一种能以时间一温度阈值控制间质热消融治疗的MR兼容性测温系统。硬件部分由MR兼容性热敏电阻探针、温度巡检仪和计算机构成。温度信号经传感器输入，经过选择、滤波、放大、模／数转换进入CPU处理，由巡检仪显示并经通讯接口输入计算机。软件设计有时间一温度阈值报警功能，一且消融条件满足Moritz阈值，计算机自动报警。

| Abstract: | Developing a MR-compatible thermometry system for using time-temperature thresholds to control interstitial thermal ablation. Its hardware consist of MR-compatible thermistor probes, a temperature circuit detector and a computer. The signal of temperature imputed from sensors, pass through the stages of selection, filtering, amplification, A/D convert, entering the CPU, displaying by temperature circuit detector and inputed computer by interface.Its software have the function of alarm, the computer is alarm as soon as the condition of ablation meet the Moritz's thresholds. |
