DICOM是存儲(chǔ)和傳輸醫(yī)療信息和圖像的領(lǐng)先標(biāo)準(zhǔn)。LEADTOOLS提供功能齊全的零占用空間DICOM查看器，以顯示DICOM圖像和來(lái)自所有學(xué)科和方式的研究。我們的可定制Web解決方案非常適合需要快速DICOM查看器且具有高級(jí)功能（例如3D體積渲染，DICOM疊加，軟拷貝呈現(xiàn)狀態(tài)等）的任何開發(fā)人員。

僅需以下幾行代碼，便可以將功能強(qiáng)大的DICOM查看器嵌入到任何網(wǎng)頁(yè)中，該查看器可以進(jìn)行窗口級(jí)別，縮放，縮放，堆棧滾動(dòng)等操作。請(qǐng)?jiān)L問(wèn)我們的文檔以獲取有關(guān)如何在Medical Viewer中加載和顯示DICOM圖像的完整教程。
