谐振电路被期望用作癌症热治疗(热疗)的植入物,其通过交变磁场有效地加热。提出了一种利用磁共振成像(MRI)设备作为激励源的热疗新技术。医院临床使用的普通1.5T型MRI设备可使植入物温度升高10 ℃。C.在实验中,在MRI系统的正常诊断程序下将RF脉冲的磁场施加到植入物。商业MRI设备可以用于热疗是有利的,因为在确认来自MRI诊断的结果之后可以重复治疗过程。实现了根据植入物在MRI中的位置控制温升。
A resonant circuit is expected to use as an implant for thermal therapy of cancer (hyperthermia), which is heated effectively by an alternating magnetic field. A new technique for hyperthermia using magnetic resonance imaging (MRI) equipment for the excitation source is proposed. Normal 1.5 T type MRI equipment of clinically used in hospital could rise the temperature of the implant up to 10 deg. C. In the experiments, a magnetic field of RF pulse under a normal diagnosis procedure of the MRI system was applied to the implant. It is advantageous that the commercial MRI equipment can be used for the hyperthermia because the therapeutic procedure can be repeated after confirming results from the MRI diagnosis. The control of the temperature rise depending on the position of the implant in the MRI is achieved.
