運用生物電阻抗技術建構一非侵入式遠距2-D成像系統應用於表層組 織病變偵測之研發

摘要


表層組織病變之疾病已不容忽視,壓瘡就是其中之一,罹患壓瘡疾病使得表層組織壞死,嚴重將導致截肢甚至死亡。此外,民國101年公佈國人十大死因中,惡性腫瘤蟬聯三十一年首位,其中口腔癌與皮膚癌也是高居第五名。為了能偵測大面積表層組織病變,使患者能及早發現就醫根治,本研究開發一套運用生物電阻抗技術搭配Zigbee無線傳輸模組與Labview軟體所組成的2-D成像系統。用以大範圍的檢測與即時成像的優點,使受測者能短時間觀察表層組織之情況,同時搭配Zigbee無線傳輸電路的設計,更提升整體檢測系統的便利性及流動性。本系統設計分為硬體與軟體兩部份;硬體部分為Zigbee無線傳輸、訊號產生器、生物電阻抗以及類比多工器電路共四種電路;軟體部分則細分為Zigbee無線模組開發程式與生物電阻抗2-D成像程式兩部份。系統開發後進行各項評估與系統測試,並由測試結果得知,各項電路與程式評估結果均和理論值相近,且從系統2-D成像圖能明確分辨出正常表層組織與病變表層組織之差異。

並列摘要


Pathological changes of superficial tissues are a serious problem in Taiwan. For example, pressure sore may cause patient’s limb amputation at the end if no attention has paid for them. Besides, oral and skin cancers are also a serious problem forcing Taiwan. In order to detect a massive area of pathological changes of superficial tissues, this study aims to develop a wireless system to image the changes of superficial tissues by the used of Labview based on bioimpedance technique. The system mainly consists of 2 parts: Hardware and software. For the part of hardware, it is composed of Zigbee transmission, signal generation, bioimpedance measurement, and multiplexers. For the part of software, it consists of Zigbee receiving and Labview imaging software. Evaluations show that the system is accuate and has the ability to show the location of the pathological changes of superficial tissues.
