摘要

目的：將影像存取系統整合於蒙地卡羅模擬程式中，以簡化轉換電腦斷層影像並建立假體的步驟。
材料與方法：本研究以BEAMnrc蒙地卡羅模擬系統作為劑量計算之軟體。藉助開放源碼軟體，及配合自行開發的程式，於平價的個人電腦上實作出相容於DICOM標準之影像存取系統，並可透過較容易使用的網頁操作方式，將電腦斷層影像轉換成劑量計算時所需的假體。
結果：本影像存取系統採用開放架構，可以連接任何具DICOM功能之臨床造影設備，成為具有影像檢索及擷取功能的影像資料庫。使用者能在瀏覽器裡面查看所需的影像，或透過網頁操作介面進行影像傳輸及轉換處理。
結論：此影像存取系統運作良好，能緊密整合於現有的造影設備、電腦治療計劃系統以及 BEAMnrc蒙地卡羅模擬程式之中。

Purpose : This study is to improve the laborious process of converting CT data sets into the simulation phantom via integrating a DICOM-compliant image archiving system with Monte Carlo Simulation.
Materials & Methods : The BEAMnrc Monte Carlo code is used for dose calculations in this study. A DICOM-compliant image archiving system is implemented using open-source software with inexpensive personal computers. Web-base software has been developed in-house to provide a user-friendly console to build the 3D patient phantom from CT data.
Results : The architecture of this image archiving system is open and any modalities supporting specific DICOM services may be attached. This system acts as a central node for query and retrieval of information stored in DICOM databases. These retrieved images can be viewed inside a Web browser or distributed among DICOM-compliant modalities. The user can also issue the command to convert these images into CT based phantoms inside the Web-based console.
Conclusion : This system works well, and integrates seamlessly with existing systems including image modalities, treatment planning systems, and BEAMnrc Monte Carlo code system.
