Value of a smartphone‐compatible Thermal Imaging Camera in the detection of peroneal artery perforators: Comparative study with computed tomography angiography
Head & Neck, 2019Co-Authors: Rui Chen, Zhi-quan Huang, Wei-liang Chen, Jian-guang WangAbstract:BACKGROUND The aim of this study was to investigate the value of a smartphone-compatible Thermal Imaging Camera in the mapping of the peroneal artery perforators. METHODS Twelve consecutive patients scheduled for fibular flap reconstruction were enrolled. The lower limbs were first studied using smartphone-based dynamic infrared thermography (DIRT). During the rewarming, the hotspots were marked, small rubber markers were taped to the registered sites, and then the patients were sent for a CT scan. The diagnostic performance of smartphone-based DIRT was evaluated by comparing the DIRT findings with CT angiography and intraoperative findings. RESULTS DIRT detected 42 of the 57 dominant perforators in 24 limbs and resulted in a sensitivity of 73.7% and a positive predictive value of 65.6%. CONCLUSIONS The sensitivity and positive predictive value of the smartphone-based DIRT are low. Currently, it should be used as an adjunctive tool together with the established Imaging techniques.

Studies of Defect Detection and Thermal Influence in Semi-Insulating 6H-SiC Substrates Using a Long-Wavelength Infrared Thermal Imaging Camera
Applied Physics Express, 2010Co-Authors: Passapong Wutimakun, Kunyong Lee, Hisashi Miyazaki, Jun MorimotoAbstract:A long-wavelength infrared Thermal Imaging Camera (IR Camera) was applied to visually evaluate the Thermal influence of defects in semi-insulating 6H-SiC substrates. Defects in substrates were rapidly and effectively detected by IR Camera observation, and the dependence of the temperature on the defect size could be observed precisely. We have applied an IR Camera to show clearly, for the first time, the change in heat propagation in areas of defects by observation of temperature distribution images in real time. Consequently, the IR Camera can be considered as an effective technique for evaluating the Thermal influence of defects.

Nondestructive Testing Technique for Defect Detection in LiNbO3 Using Infrared Thermal Imaging Camera
Japanese Journal of Applied Physics, 2010Co-Authors: Kunyong Lee, Hisashi Miyazaki, Yoichi Okamoto, Jun Morimoto, Kohji TodaAbstract:The existence of defects in lithium niobate (LiNbO3) degrades the specific properties required of LiNbO3 as substrate material, which is a major problem inhibiting device constructions. For the purpose of providing a convenient and quick tool for use in a nondestructive testing technique for defect detection, the feasibility of using an infrared Thermal Imaging Camera (IR Camera) is examined by comparing the results of IR Camera use with those of two methods, scanning laser microscopy (SLM) and light scattering tomography (LST). We have succeeded in the detection of defects in the LiNbO3 substrate by observing the Thermal properties of defects in a relatively wide field of view (8×6 mm2) compared with the case of using conventional microscopes. The maximum temperature difference of the defects in the LiNbO3 substrate was 0.47 K.

Characterization of Defects in Semi-Insulating 6H-SiC Substrates Using IR Thermal Imaging Camera
Materials Science Forum, 2010Co-Authors: Kunyong Lee, Hisashi Miyazaki, Yoichi Okamoto, Jun MorimotoAbstract:We have detected defects micro-pipes and a cluster of impurities in semi-insulating 6H-SiC substrates using long-wavelength infrared Thermal Imaging Camera (IR-Camera) with 8 ~ 14 µm in non-destructive and non-contact. Also we have evaluated the Thermal influence of defects on the entire substrates from the observation results of scanning laser microscope (SLM) and light scattering tomography (LST). Through the process, it was certificated that the defects in the substrates could be detected with relatively macroscopic scale (8 6 mm2). Moreover, through a temperature profile processing by a 0.1 K Thermal resolution, we estimated Thermal behavior of the defect areas in the 6H-SiC precisely. The IR-Camera is considered as effective technique for evaluating the defects in the intermediate range between micro and macro scale.
