V-PDT窄帶光血管圖像的量化分析研究V-PDT窄帶光血管圖像的量化分析研究

摘要：光動(dòng)力療法已廣泛應(yīng)用于治療不同類型的腫瘤和非腫瘤性病變。然而，單純的光動(dòng)力照射對(duì)于治療癌癥并不總是足夠的，因此新的光動(dòng)力治療技術(shù)應(yīng)運(yùn)而生，其中包括了多種類型的光動(dòng)力療法。其中最有前途的是血管內(nèi)光動(dòng)力療法，其可在選擇性侵入性的情況下迅速殺死癌細(xì)胞。因此，本研究旨在研究V-PDT窄帶光血管圖像的量化分析方法。對(duì)窄帶光血管圖像進(jìn)行分析，我們可以從多個(gè)方面來(lái)觀察目標(biāo)區(qū)域的組織變化，以此得到更加準(zhǔn)確的結(jié)果，例如血管密度和血管形態(tài)等。為了實(shí)現(xiàn)這一目標(biāo)，我們采用了基于圖像處理技術(shù)和計(jì)算機(jī)視覺(jué)技術(shù)的方法。在研究實(shí)施中，我們進(jìn)行了大量的圖像處理和量化分析試驗(yàn)，以便測(cè)量目標(biāo)區(qū)域的相關(guān)特征。最終得到了實(shí)驗(yàn)結(jié)果，表明了V-PDT窄帶光血管圖像的量化分析方法是可靠和有效的。在以后的臨床應(yīng)用中，該方法可被用于光動(dòng)力療法的治療效果評(píng)估以及隨訪。
