激光热疗光源控制系统的研制

Development of illuminant control system of laser thermotherapy

研制了多波长的激光消融控制系统,该系统可单独或组合输出多种波长激光,在MRI实时影像引导下,将激光经磁兼容光路导入病灶,实现肿瘤消融。本文设计的系统可控制激光功率、脉宽、时间、温度等多种参数,并通过动物实验提出一种行之有效的治疗方案及参数,在激光消融肿瘤及相关领域具备进一步丰富现有医疗方案的潜力。

In this paper,a multi-wavelength laser ablation control system is developed,which can output multiple wavelength lasers individually or in combination,and under the guidance of MRI real-time image,the laser is introduced into the lesion via magnetically compatible optical path to realize tumor ablation.The system designed in this paper can control various parameters such as laser power,pulse width,time,temperature,etc.,and propose an effective treatment plan and parameters through animal experiments,which has the potential to further enrich the existing medical solutions in the field of laser ablation of tumors and related fields.
