Huge amounts of isotropic data with a thickness of 0.5 or 1.0 mm are generated by Multislice CT. Current film-based reading systems are not suitable for interpreting the large amounts of data. So, it is necessary to develop new real-time volume visualizing system for multislice CT. Real-time isotropic MPR at any directions is extremely required in clinical use. Using MPR/MIP using isotropic data, accurate diagnosis is possible without the presence of a partial volume effect. Our system using general-purpose Windows-based computer and DICOM freeware/low price software (Exa Vision ; ZIO) enables us to effectively utilize the volume data acquired using multislice CT in routine clinical diagnosis. The amount of data generated is a massive 10,000 to 20,000 slices each day in a 4-row multislice CT, corresponding to 1.2-2.4TB/year. Images are transferred from MSCT to the server and from server to the reading workstation at a rate of 5-6 slices/sec, which rate is not so high. Our system has several problems in routine diagnosis.

多层CT可生成大量厚度为0.5或1.0毫米的各向同性数据。当前基于胶片的读取系统不适合解释大量数据。因此，有必要开发新型的多层CT实时体积可视化系统。临床使用中非常需要任意方向的实时各向同性MPR。使用使用各向同性数据的 MPR/MIP，可以在不存在部分体积效应的情况下进行准确诊断。我们的系统使用基于 Windows 的通用计算机和 DICOM 免费软件/低价软件（Exa Vision；ZIO），使我们能够在常规临床诊断中有效利用多层 CT 获取的体积数据。 4 排多层 CT 每天生成的数据量高达 10,000 至 20,000 个切片，相当于每年 1.2-2.4TB。图像从 MSCT 传输到服务器，再从服务器传输到读取工作站，速度为 5-6 切片/秒，该速度并不是很高。我们的系统在日常诊断中存在一些问题。
