Thermograms with reflection artifacts, but not meridians, from a volunteer. The moxa cigar (length 20 cm, diameter 1.5 cm; Hunan, China) used for stimulation (distance about 10 cm, duration about 5 - 10 min) is visible as a circular white area (average temperature 550°C; measured with Flir ThermaCAM S65 with an energy maximum ranging from 3 - 3.5 μm [16]). Dependent on the angle of reflection, technical reflection effects visible as lines at optional parts of the body (a - d) can occur. The thermographic scale was defined from blue (25°C) to red/white (41°C). From [16].
