使用非侵入性的组织识别成像术于真皮组织与水晶矿石之深层造影

Design and Application of Noninvasive Tissue Recognition Imaging in Tomography of Human Skin and Crystal Structure

欲了解皮肤深层的状况,使用三维医学影像技术实属必要,作者提出(组织识别成像术)的新技术,以减低扫描光源对组织之侵入性。先建立皮肤内各种不同组织如黑色素、胶原蛋白、血红素的反射光谱以组成组织数据库;于实际扫描待测皮肤时,依序读出样本组织深层中各空间点的反射光谱,将各点的反射光谱与组织数据库中各种组织的反射光谱做交叉相关程度之运算,可侦测出扫描的各点属于肌肤中的何种组织。其次,再于成像程序中依序给予各点以各对应组织的颜色,即可产生彩色的肌肤深层显像。组织识别成像术具有系统简单、成本低廉、彩色成像等优点,且对组织达到真正的非侵入性,将可将之微小化成为个人式、可携式的肌肤检测仪,对于美容市场极具潜力。

Cosmetic industry grows fast in recent years.To reveal the image of dermal structure,it is necessary to apply three-dimensional medical imaging technology. To reduce the invasiveness of laser source on tissues,tissue recognition imaging is proposed to retrieve the intrinsic optical property,namely,the reflection spectrum of every scanned point for imaging.The reflection spectra of main kinds of skin tissue,such as melanin,collagen and hemoglobin,were established as reference database.Broad-band rays were then employed to derive the reflection spectrum of each scanned sample element;the tissue type of the scanned point was identified by cross-correlation of the derived spectrum and the database.In imaging program,all scanned points were filled in with their corresponding tissue color,e.g.black for melanin,white for collagen,or red for hemoglobin,and finally the colored skin tomography resulted.Tissue recognition imaging has merits of easy configuration,low cost,color imaging,high resolution and real non-invasiveness.Substituting LED modules for its spectrometer,tissue recognition imaging is promising to be miniaturized as personal and portable skincare devices,which have great potential in future cosmetic market.
