The authors developed a real-time, interactive three-dimensional (3D) segmentation pipeline that uses relatively low-level segmentation operations and provides two-dimensional and 3D visualization through a user-friendly graphical interface.
The low-level segmentation processes were implemented on a massively parallel computer; the graphical user interface was written with a public domain software toolkit. Since their implementation 2 years ago, these segmentation tools have been applied to approximately 300 computed tomographic and magnetic resonance imaging data sets. Two typical clinical cases are presented to demonstrate their applications.
The entire processing pipeline can be executed in a few seconds. The tools are simple to learn because they involve the use of low-level procedures and a user-friendly graphical interface with a short interactive response time. Segmentation of the bones, aorta, kidneys, and kidney cysts in case 1 could be performed in about 16 minutes. The time needed to segment each organ in case 2 ranged from about 15 minutes for the skin and brain to about 1 minute for the tumor.
Satisfactory results can be obtained in a relatively short time with the real-time interactive 3D segmentation system. Operation of the system can be easily learned by a wide variety of nonspecialized users with some medical background.
作者开发了一种实时交互式三维(3D)分割流程,该流程使用相对低级的分割操作,并通过用户友好的图形界面提供二维和三维可视化。
低级分割过程在大规模并行计算机上实现;图形用户界面使用公共领域软件工具包编写。自两年前实施以来,这些分割工具已应用于约300个计算机断层扫描和磁共振成像数据集。本文展示了两个典型临床病例以说明其应用。
整个处理流程可在几秒内执行完毕。这些工具易于学习,因为它们涉及使用低级程序以及具有短交互响应时间的用户友好图形界面。病例1中骨骼、主动脉、肾脏和肾囊肿的分割大约需要16分钟。病例2中分割每个器官所需时间从皮肤和大脑的约15分钟到肿瘤的约1分钟不等。
使用实时交互式3D分割系统可在相对较短时间内获得满意结果。具有一定医学背景的各类非专业用户均可轻松学会该系统的操作。
