Remote Access to Radiotherapy Treatment Planning Information: Demand Analysis and Prototype Implementation

病患的治療計劃資料除了用於放射治療之外，其中亦包含許多寶貴的臨床研究資訊如解剖位置、組織輪廓、治療方向與劑量分布，本研究嘗試建置一套網頁式數位存取系統藉以提供即時的病患放射治療計劃資訊。本系統簡稱DAS可當作現今市面上不同廠家的放射治療計劃系統的虛擬印表機，自動擷取來自治療計劃電腦的列印資料，並將其轉換成數位圖像儲存於系統資料庫中，這些治療計劃相關圖像如劑量分布圖、劑量體積卡方圖(DVH)、數位重組影像等可經由Apache網頁伺服器與Coppermine圖像軟體加以呈現，唯有經授權的使用者可以在遠端透過網頁瀏覽器操作介面進行檢索與查看圖像。這雛型系統可使不同治療計劃間的檢閱與比較更加方便及更有效率。

Digital data from radiotherapy treatment planning systems (RTPS) is generally used for patient planning only, but it also contains enormous quantities of valuable information regarding patient anatomic geometries, tissue outlining, treatment approaches and dose distribution. Attempts on implementing a Web-based digital archiving system (DAS) in order to provide immediate access to the treatment planning information were described in this article. The DAS served as a universally virtual printer for diverse RTPS, and it could transparently intercept print job and archive them into its database automatically. These treatment planning images such as dose distribution images, dose volume histograms (DVHs), and digitally reconstructed radiographs (DRRs) in the DAS were registered to the Apache Web server by Coppermine photo gallery, and were made available for authorized users to search and browse using a simple Web browser. This prototype allowed for rapid review and remote comparison of treatment plans efficiently and conveniently.
