In the field of medicine, temperature is a very important physiological parameter. In tumor hyperthermia, real-time monitoring of human body temperature and ablation site temperature is required to ensure accurate and uniform heating of tumor tissue, so that it can reach the critical death temperature and maintain normal tissue without thermal damage. The measurement requires sufficient accuracy, generally reaching ± 0.1-0.2 ℃. 加えて, temperature sensors used in tumor hyperthermia not only measure tissue temperature in real-time, but also eliminate the problem of traditional thermometers being affected by electromagnetic radiation interference. Heat therapy is an emerging technology in the field of tumor treatment, 物理的方法を使用して腫瘍領域を効果的な治療温度まで加熱し、それを一定期間維持します。, 正常組織への損傷を最小限に抑えながら腫瘍細胞を殺すという治療目標を達成する.

温熱療法機器には主に高周波容量性温熱療法機が含まれます, 超音波温熱療法機, およびマイクロ波温熱療法機. 高周波容量性ハイパーサーミアマシンの電場分布を均一に制御するのは簡単ではありません, 深加熱は難しい. 使用時, 脂肪は過熱や痛みを引き起こしやすい, 脂肪が薄い部分にのみ適しています (厚さ ≤ 1.5cm); 超音波温熱マシンはガスを含む空洞を通過できません. マイクロ波温熱療法は比較的理想的な温熱療法です。. The goal of microwave hyperthermia is to obtain a relatively high thermal dose to the tumor target area, avoiding the occurrence of treatment cold spots, while also protecting normal tissues as much as possible to minimize the thermal dose to avoid treatment hot spots and irreversible damage. Temperature measurement is an important technology to ensure the quality of hyperthermia. In order to ensure the therapeutic effect, it is necessary to heat the tumor tissue to an effective therapeutic high temperature zone of 43-45 ℃, without damaging the surrounding normal tissues, and ensure that the temperature of normal tissues is below 40 ℃. In the early days, the heating power was controlled solely based on the patient’s thermal sensation. 最近では, many thermal therapy machines use intermittent shutdown temperature measurement methods, resulting in large temperature measurement errors. The existing microwave hyperthermia technology, due to the inability to synchronously monitor temperature in real-time during the microwave hyperthermia process, results in unsatisfactory hyperthermia effects, and the safety and reliability of microwave hyperthermia are low.

The three-dimensional targeted microwave tumor hyperthermia machine is equipped with fiber optic temperature sensors on the base of the microwave radiators, and the temperature measurement fiber is set on the 光ファイバー温度センサー, achieving the integration of the microwave radiators and temperature measurement fiber. This allows the microwave radiators and temperature measurement fiber to reach the lesion simultaneously, achieving precise temperature monitoring of the hyperthermia process using fiber optic temperature sensors. In addition to ordinary industrial temperature measurement, other fields such as biomedical engineering can also use 光ファイバー温度測定 for detecting the temperature inside the biological cavity.
