In this technical report we describe the thermographic setting protocol suitable for the FLIR T650SC thermal imager (FLIR Systems, Inc., Wilsonville, OR), an instrument that detects electromagnetic radiation in the infrared field which is physiologically emitted from the human body. FLIR T650SC thermal imager processes infrared radiations graphically and analyzes them through a specific software. In biomedicine, infrared thermography is a promising technique amongst other conventional methods used for detecting skin temperature differences considered as a possible sign of disturbances in the human body. Currently, automatic screening of temperature from a safe distance is an instrument utilized in the front line of the SARS CoV2 emergency. The processing method of the thermogram considers an initial setting of constant parameters that cannot be subsequently modified such as temperature range, focusing and image composition. After the acquisition variable values important in the processing and analysis of the thermogram, such as detection of environment temperature, reflected temperature, emissivity, relative humidity and contrast palette, are set in the software. The analysis is performed using the FLIR Tools software. In the biomedical field standardized acquisition of thermograms facilitates the identification of trigger points and areas of hyper- and hypothermia distributed on the skin surface and muscle bundles. The protocol made it possible to create images with the same acquisition method for all patients. The thermal imaging camera is a valid screening tool because its execution is rapid, it is non-invasive, well-tolerated, and at a low cost for patients.
在本技术报告中，我们描述了适用于FLIR T650SC热成像仪（FLIR Systems公司，俄勒冈州威尔逊维尔）的热成像设置协议，该仪器可检测人体生理发射的红外场中的电磁辐射。FLIR T650SC热成像仪以图形方式处理红外辐射，并通过特定软件对其进行分析。在生物医学中，红外热成像技术是一种很有前景的技术，与其他用于检测皮肤温度差异的传统方法相比，皮肤温度差异被视为人体可能出现紊乱的迹象。目前，在SARS-CoV2疫情应急的前线，一种能在安全距离自动筛查体温的仪器得到了应用。热成像图的处理方法考虑了一些初始设置的恒定参数，这些参数随后无法修改，如温度范围、聚焦和图像构图。在采集后，软件中会设置热成像图处理和分析中重要的可变值，如环境温度检测、反射温度、发射率、相对湿度和对比度调色板。分析使用FLIR Tools软件进行。在生物医学领域，热成像图的标准化采集有助于识别分布在皮肤表面和肌肉束上的触发点以及体温过高和过低的区域。该协议使得为所有患者采用相同的采集方法创建图像成为可能。热成像相机是一种有效的筛查工具，因为其操作快速、无创、耐受性好且对患者成本低。
