[生醫科技] 成大研發家用乳癌早期偵測裝置

國立成功大學研發團隊研發一種只有手機大小的「近紅外線乳癌早期偵測裝置(Near Infra-Red Breast Cancer Early Detection and Warning Device)」,利用能穿透人體組織而波長約 650-1050 奈米之紅外線光源,透過人類皮膚,可偵測到人體組織內可能的癌細胞,目前已完成人體模擬測試,待臨床測試之後可望量產,造福全世界人類!該裝置不需侵入人體、簡易操作、價格低廉且具高功能,預計成本是不會比iPhone高,女性在家甚至穿著衣服也能自我檢查!

由於癌細胞消耗氧氣的速率與正常細胞不同,所呈現的吸收散射現象也異於正常細胞,根據這種特性,成大團隊研發的「近紅外線乳癌早期偵測裝置」由具有七種不同波長的近紅外線光源元件打出光源到人體組織、再以光偵測器接收散射回來的訊號、使用訊號擴大器將微弱的人體訊號放大、再進入數值保持元件延長訊號停留時間以供處理、接下來以訊號過濾元件濾掉無關的雜訊、再進入單晶片以數位方式計算訊號、其結果以液晶面板呈現、並能儲存在記憶卡中,提供醫生做為診斷的依據。

這種技術還能運用到腦部氧氣濃度或人体血糖值的偵測上。增加靈敏度及訊息分析的功能之後,其他在體內更深層的病變也能運用此科技檢驗出來。

[Biomedical] NCKU Invents Mini Cancer Earlier Detection Device for Home Use

An NCKU research team develops a cellphone-sized Near Infra-Red Breast Cancer Early Detection and Warning Device, which can detect cancer cells by means of 650- to 1050- nanometer infra-rays. Now the experiments on human body have been completed; hopefully the device can go through clinical examinations and get ready for mass production in the near future. The device is non-intrusive, user friendly, low-cost (perhaps lower than iPhone) and effective. The users can easily conduct the self-detection without having to go out to a hospital or even undress at all.

Because the speed rate of oxygen consumption in cancer cells is different from the ordinary cells, the difference of light absorption and scattering features can be observed as indication to tell cancer cells from ordinary cells. Based on this remark, the NCKU research team develops the Near Infra-Red Breast Cancer Early Detection and Warning Device. The device has a light source which can project infra-rays in seven different wavelengths into human body tissue and a sensor detecting the reflection. By means of the signal amplifier embedded, the responded signals of human body information are magnified for further purification in the filter and the digital analysis in an SoC. The analysis result can be shown with an LCD panel and recorded in a memory card, which is easy for diagnosis.

This technique can be applied to the detection of oxygen density in the brain and blood sugar as well. If the sensitivity of the device can be refined, more deep pathological changes could be detected with it.
