OCT (Optical Coherence Tomography: 光干渉断層撮影)とは、光の干渉性を利用して測定対象内部の微細構造を画像化する技術です。
1700 nm帯の広帯域波長光源を用いることで、高散乱な生体組織の深部の高分解能イメージングが可能です。具体的には、SD-OCM (Spectral Domain - Optical Coherence Microscopy)により、開頭手術なしの非侵襲脳神経細胞深部イメージングができるため、アルツハイマー病変のIn-vivo観察などで応用されています。

For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors. To do this, a site will create small text files which are placed on visitor’s devices (computer or mobile) - these files are known as cookies when you access a website. Cookies are used in order to make websites function and work efficiently. Cookies are uniquely assigned to each visitor and can only be read by a web server in the domain that issued the cookie to the visitor. Cookies cannot be used to run programs or deliver viruses to a visitor’s device.
Cookies do various jobs which make the visitor’s experience of the internet much smoother and more interactive. For instance, cookies are used to remember the visitor’s preferences on sites they visit often, to remember language preference and to help navigate between pages more efficiently. Much, though not all, of the data collected is anonymous, though some of it is designed to detect browsing patterns and approximate geographical location to improve the visitor experience.
