體外血液相容性測試非常依賴影像系統提供足夠多量之資訊，以作進一步之分析及血液相容性判斷。本實驗主要是建立以倒立式光學顯微鏡為主之影像系統，觀察血小板吸附實驗之材質表面，輔以數位式影像擷取器做數位影像擷取，所取得之影像再經電腦軟體處理、分析。本系統之優點在於1.)可取代SEM為血小板吸附實驗觀測儀器，避免SEM試片前處理對表面所造成之不確定干擾，且操作費用便宜；2.)可應用於其他表面微觀觀測；3.) 連續監測系統之建立有助發展體外(in vivo)流動態(in situ)實驗，有助研究血小板吸附之動力機構，本系統可進一步應用於流動態血液吸附實驗觀測。
本實驗中，共選擇了10種材料表面於顯微鏡下觀察血液吸附測試結果，其中包含了8種PU並參考以往文獻以酸氧化處理玻璃表面作為對照組。血液相容性測試結果，PU中以含氟之PU血小板吸附量較少，而含離子基COONa及含SO3Na等離子性PU則表現較差。在實驗過程中，發現不同於以往酸氧化處理的玻璃表面血小板瘋狂吸附之情形，經NaOH浸泡處理過之玻璃，在血液相容性上有優異之表現，此情形非常特別。

Platelet adhesion is one of the ways for hemocompatibility assessment, in which great amount of image information is in demand for in vitro investigation. The aim of this study is to set up an image system for the observation for the phenomena occurring during blood-material contact. With the aid of CCD, frame grabber and computer etc., images of the material surface before and after the platelet contact were obtained for further analysis of platelet adhesion density and adherent platelet morphology。
There were 10 materials tested, including eight kinds of polyurethanes (PU) and two kinds of treated glasses. The fluorine-containing PUs showed lower platelets adhesion density while the ion-containing PUs (COONa and SO3Na-containing polyurethanes) showed higher values. Amazingly, NaOH treated glass, unlike well-studied acid-oxidized-glass, was found to be relatively better in platelet compatibility, in terms of lower platelet adhesion density and less activated platelet morphology.
The system was examined to function well from static platelet adhesion experiments. The advantages of this image system comparing with SEM are cheaper in operating and is facilitating to hemocompatibility study in flow system。
