摘要:

报道了一种小动物活体荧光-光热双模成像系统, 其兼具荧光成像和热成像双功能, 具有成像灵敏度高、 采集速度快(≤51 frame/s)、 组织穿透深度大(近红外荧光成像时可达10 mm)以及0.1 ℃的热成像分辨率. 该系统不但能够实现小动物皮下肿瘤和深层组织/器官的荧光成像, 同时集成了热成像, 可实时监测光热治疗中的温度变化以及药物的控制释放过程, 有助于实现精准治疗.

关键词: 荧光成像, 热成像, 药物控制释放, 诊疗一体

Abstract:

This study reports a small animal in vivo fluorescence-photothermal dual-mode imaging system, which has dual functions of fluorescence imaging and thermal imaging. The system has high imaging sensiti- vity, fast acquisition speed(≤51 frame/s), and large tissue penetration depth(near infrared fluorescence up to 10 mm during imaging), and a thermal imaging resolution of 0.1 ℃. The system can not only achieve fluorescence imaging of small animal subcutaneous tumors and deep tissues/organs, but also integrates thermal imaging to monitor temperature changes in photothermal therapy in real time, as well as the controlled release process of drugs to achieve precise treatment.

Key words: Fluorescence imaging, Thermal imaging, Drug controlled release, Diagnosis and treatment integration
