Acupoint Thermal Radiation Characteristics in Adolescents with MDD

A thermograph (NEC InfRec R450, Avio Infrared Technologies Co., Ltd., Tokyo) was used to record thermal images. The infrared camera was fixed on a tripod 1 m away from the subject to ensure that no shaking movements or vibrations occurred during the recording of thermal images. MDD related acupoints on the inner and outer sides of the limbs were detected. Appropriate body position was selected according to the different parts to be detected. Using the automatic interval saving shooting mode, one thermal picture was taken at 10-s intervals, 3 pictures were taken for each subject.
