  • Neurosensory dysfunction of the injured inferior alveolarnerve(IAN) is a common and distrssing consequence of traumatic or iatrogenic injury. Conventional neurosensory testing has been used to detect and monitor sensory impairments of the injured IAN. However, these tests had low reliability and are not qualitative at best because they are based on solely on the patient's subjective assesment of symptoms. Consequently, there is need for more reliable, sensitive, and objective test measures to document and to monitor sensory dysfunction of the trigeminal nerve. This study was to investigate DITI's (digital infrared thermographic imaging) potential as a diagnostic alternative for evaluating of the nerve injures and sensory disturbance. Subjects were 30 patients who had been referred to Ewha Medical Center due to sensory disturbance of the lower lip and chin followed after unobserved inferior alveolar nerve injuries. The patients were examined by clinical neurosensory tests as SLTD (static light touch discrimination), MDD (moving direction discrimination), PPN (pin prick nociception) and DITI (digital infrared thermographic imaging). The correlation between clinical sensory dysfunction scores(Sum of SLTD, MDD, PPN, NP, Tinel sign) and DITI were tested by Spearman nonparametric rank correlation anaylsis & Kruskal-Wallis test, Wilcoxon 2-sample test. This study resulted in as follows; (1) The difference of thermal difference between normal side and affected side was as ${\Delta}-3.2{\pm}0.13$. (2) The DITI differences of the subjects presenting dysesthesia of the lip and chin were correlated significantly with the neurosensory dysfunction scores(r=0.419, p=0.021)and SLTD (r=0.429, p<0.05). (3) The MDD, PPN, NP, Tinel sign, duration, gender were not correlated with DITI(p> 0.05). Therefore, the DITI(digital infrared thermographic imaging) can be an option of the useful objective diagnostic methods to evaluate the injured inferior alveolar nerve and sensory dysfunction of trigerminal nerve.

  • Objectives: This study was designed to investigate characteristics of digital infrared thermal imaging (DITI) and quantitative evaluations in patients with burning mouth syndrome (BMS). Methods: We reviewed the clinical records of 38 patients with BMS who visited the Oral Diseases Clinic of Kyung Hee University Korean Medicine Hospital from March 1st, 2018 to June 30th, 2018. The subjects were evaluated with digital infrared thermal imaging (DITI) and for heart rate variability (HRV), unstimulated salivary flow rate (USFR), and the proportion of coated tongue. Results: Most patients showed higher temperatures on the central part of the tongue (T2) than on the middle of the forehead (T1). The patients tended to have a high Low frequency/High frequency (LF/HF) ratio. Statistically significant negative correlations were noted between the age of patients and the temperature of T1 and T2. Statistically significant negative correlations were also observed between the LF/HF ratio and 'T1-T2' values. Conclusions: This study suggests that DITI and HRV are useful for the validation of patients with BMS. Correlations between the result values suggest that sympathetic function acceleration is related to temperature distribution and, ultimately, to symptoms.

  • Objectives: The purpose of this study is to analysis differences of heart rate variability (HRV), body composition, digital infrared thermal imaging (DITI), and electro pulse graph by whether there are some causes of dysmenorrhea or not. Methods: We studied 89 patients who took at least one test among HRV, Body composition, DITI, and electro pulse graph visiting Kyung Hee University Hospital at Gangdong from March 1, 2014 to May 7, 2019. Results: There were statistically significant differences in Low frequency (LF), LF norm and High frequency norm (HF norm) of HRV between primary dysmenorrhea patients and secondary dysmenorrhea patients. There were statistically significant differences in Body Mass Index (BMI) and body fat percentage of Body composition between two groups. But both BMI were included in normal range. There were no statistically significant difference in DITI results. And there was significant difference of Estimated circulation resistance (ECR) between two groups. Conclusions: The results suggest that hormone imbalance of secondary dysmenorrhea patients can affect HRV results. And because of high ECR, phlegm pathology can be more considered in secondary dysmenorrhea patients. Further study should be conducted to confirm the results of body composition and DITI differences.

  • We have developed and applied a diagnostic Multi-Leaf Collimator (MLC) to optimized the X-ray field in medical imaging and the usefulness evaluated through the fusion of infrared image and X-ray image acquired by infrared camera. The hand and skull radiography with multi-leaf collimator(MLC) showed significant area dose reductions of 22.9% and 31.3% compared to ARC and leakage dose was compliant with KS A 4732. Also scattering doses of 50 cm and 100 cm showed a significant decrease to confirm the usefulness of MLC. It was confirmed that the fusion of infrared images with an adjustable degree of transparency was possible in the X-ray images. Therefore, fusion of anatomical information with physiological convergence is expected to contribute and improvement of diagnostic ability. In addition, the feasibility of convergence X-ray imaging and DITI devices and the possibility of driving MLC with infrared images were confirmed.

  • Objectives : It is the object of Qigong therapy to promote the circulation of Qi and blood, and to relieve mentality by way of warming lower Danjon. In this study, to prove that Qigong therapy could actually subside heat on upper or middle Danjon and warm the temperature on lower Danjon, we observed the thermal changes of upper, middle, lower Danjon before and after Qigong therapy and compared them. Methods : We selected 16 patients, treated Qigong therapy and examined by D.I.T.I.(Digital Infrared Thermographic Imaging) before and after Qigong therapy, among patients who visited. Qigong clinic, Kangnam Korean hospital, Kyunghee University(Daechi-2dong, Kangnam-Gu) from april to october, 1999. We watched the difference of temperature among upper, middle, lower Danjon before and after Qigong therapy, and used student T-test(paired type, 2 tail) for proving effects of Qigong therapy statistically. Conclusions 1. The difference of temperature$({\Delta}T)$ between upper(Ex-HN3) and lower Danjon(CV4) significantly decreased about $0.55^{\circ}C$ after Qigong therapy(p<0.01). 2. The difference of temperature${\Delta}T$ between middle(CV17) and lower Danjon(CV4) significantly decreased about $0.39^{\circ}C$ after Qigong therapy(p<0.05). 3. The difference of temperature${\Delta}T$ between upper(Ex-HN3) and middle Danjon(CV17) decreased about $0.25^{\circ}C$ after Qigong therapy, but it was not statistically significant.

  • Purpose: This study examined the effects of beraprost sodium on digital infrared thermal images in patients with peripheral arterial disease caused by type 2 diabetes mellitus. Materials and Methods: Twenty-five diabetic patients with peripheral arterial disease were treated with beraprost sodium in a prospective, multicenter, cohort study from February 2013 to December 2014. Beraprost sodium ($40{\mu}g$) was administered orally 3 times daily ($120{\mu}g/day$) for 6 months. The visual analogue scale (VAS) and digital infrared thermal imaging (DITI) were performed to compare the blood flow improvement between before and after dosing. Results: Among the 25 patients included in the evaluation, 22 patients completed the study. A significant increase in body temperature was observed in the front and left side, particularly in the plantar side in DITI compared to that before and after administration. An increase in body temperature was observed at the frontal part from $28.1^{\circ}C{\pm}2.3^{\circ}C$ to $29.1^{\circ}C{\pm}2.1^{\circ}C$ (p=0.021), at the left side from $27.8^{\circ}C{\pm}2.4^{\circ}C$ to $28.6^{\circ}C{\pm}1.9^{\circ}C$ (p=0.028), at the plantar part at $24.0^{\circ}C{\pm}1.5^{\circ}C$, and at the plantar part at $27.1^{\circ}C{\pm}2.4^{\circ}C$ (p<0.01). The VAS decreased significantly from $5.4{\pm}1.3$ to $2.7{\pm}2.0$ after 6 months of treatment (p<0.01). Conclusion: Beraprost sodium is a safe and easy-to use oral medication for diabetes peripheral arterial disease. It can be expected to increase the blood flow and decrease the lower extremity pain statistically after being taken for 6 months.

  • Objectives This study is planned to classify correlation between HIVD of L-spine MRI and Digital Infrared Thermal Image (DITI). Methods We measured the temperature of both leg whose 120 men and 116 women patients with lumbar pain in Bucheon Jaseng Korean Medicine Hospital. And We use Magnetic Resonance Imaging (MRI) for classifying the patients who has lumbar intervertebral disc or not. Results 1) There was no statistical relation between difference of both leg's temperature and gender (p>0.05). 2) There was meaningful statistical relation between difference of both leg's temperature and age (p<0.05). 3) There was meaningful statistical relation between direction of HIVD of L-spine and direction of temperature reduction. 4) There was meaningful statistical relation between the severity of HIVD of L5/S1 and degree of temperature reduction. But there was no statistical relation between the severity of HIVD of L3/4, L4/5 and degree of temperature reduction. Conclusions We can use Digital Infrared thermal image (DITI) on low back pain patients for diagnosis. But we should not use DITI alone. DITI has limit in diagnosis.

  • 산간계곡에는 특히 야간에 찬 공기가 흘러 고이는 일이 흔한데, 이런 곳의 식생은 생장과 발육이 그렇지 않은 주변지역에 비해 달라질 수 있어 관심의 대상이 다. 이 연구는 작은 규모의 집수역에서 적외선 영상을 이용하여 냉기호와 온난대의 형상을 가시화 할 수 있는지 알기 위해 수행하였다. 경남 하동군 악양면 형제봉(해발 1,117m)에 적외선 영상 복사계를 설치하여 관측여건이 양호했던 2011년 5월 17일 새벽부터 일출시까지 악양계곡의 열영상을 $640{\times}480$ 해상도로 획득하였다. 열영상 분석결과 계곡의 바닥에 나타난 낮은 온도 분포에 의해 찬공기의 배수를 인지할 수 있었고, 계곡 양쪽 사면에서 바닥보다 $5^{\circ}C$ 높은 온난대의 실체를 확인할 수 있었다. 적외선 영상을 이용하면 기존 고해상도 디지털 기온분포도 '전자기후도'의 신뢰성 검증이 한층 수월해져서 전자기후도 실용성 확보에 도움이 될 것이다.
