中文摘要 | 糖尿病患者由於其末梢感覺神經以及自主神經的受損,再加上糖尿病患者容易併發有小血管疾病,因此糖尿病患容易出現肢體末端有潰瘍的現象。若未能早期發現,潰瘍的患部可能會造成有骨髓炎,組織壞死,嚴重者更可能會造成患側的截肢。因此若能儘早發現,並對於此部位給予適當的處理,就能降低糖尿病足截肢的產生。本研究與成大醫院整形外科合作,在實驗組及對照組的受測者分別為足底潰瘍的糖尿病患者及沒有糖尿病的外傷病患,兩組皆需接受植皮手術。利用紅外線熱攝影機擷取受測者手術前後動態與靜態分別為100張與600張的熱影像,並且利用卡氏轉換(Karhunen-Loéve transform),回溫趨勢以及溫差百分比三個參數來對病患的足部熱影像做分析。由於糖尿病患者在接受手術後植皮部位的周圍容易發生小血管的血流偷竊現象,因此在糖尿病患者的傷口周圍其血液循環會變差。而在動態分析的結果,利用卡氏轉換及回溫趨勢皆可明顯發現此糖尿病患傷口周圍有此現象,而回溫趨勢的在計算量上會比卡氏轉換減少了許多。因此利用回溫趨勢可以找出血液循環病變的區域,並減少資料的計算量。 |
英文摘要 | Due to the deficiency of peripheral sensory and autonomic nerves and the complication of peripheral vascular disease, the patients with diabetes are prone to induce the ulcers on their limbs. If the ulcer formation or poor circulation area can be detected as early as possible, the occurrence of amputation morbidity may be reduced. In this study, the thermal image analysis is applied to characterize the superficial circulation of foot. Nine subjects with or without diabetes needing skin graft are recruited and divided into control group and experimental group. Both static and dynamic thermal images are acquired for analysis. The temperature difference percentage, Karhunen-Loéve transform, and thermal recovery tendency analysis are employed for thermal image analysis. From the results, it is shown that the area of poor circulation around the wound in the patients with diabetes may be significantly revealed using Karhunen-Loéve transform and thermal recovery tendency analysis. The thermal recovery tendency analysis needs shorter computation time and is a good parameter to early detect the ulcer formation. |
