A clinical hyperthermia system using a 915 MHz microwave generator and incorporating multipoint thermocouple thermometry is described. Temperatures can be monitored simultaneously at 16 points and measurements displayed on a visual display unit and a plotter. The power output of the generator is adjusted under computer control to maintain a constant predetermined temperature in a chosen control channel. A clinically useful feature of the system is the ability to determine the effective cumulative thermal dose delivered to the tissue at points monitored in real time. The basis for the thermal dose calculation is discussed in detail. The calculated dose parameter is displayed for each of the 16 channels during the treatment and updated every 30 s. This real-time display of a thermal dose parameter has made possible a more homogeneous heating of tumours.
描述了一种使用915兆赫微波发生器并结合多点热电偶测温法的临床热疗系统。可同时在16个点监测温度，并在可视显示单元和绘图仪上显示测量结果。发生器的功率输出在计算机控制下进行调整，以在选定的控制通道中维持恒定的预定温度。该系统的一个临床有用特性是能够实时确定在监测点传递到组织的有效累积热剂量。详细讨论了热剂量计算的基础。在治疗期间，为16个通道中的每个通道显示计算出的剂量参数，并每30秒更新一次。这种热剂量参数的实时显示使肿瘤加热更加均匀成为可能。
