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.

多层螺旋CT可产生大量厚度为0.5或1.0 mm的各向同性数据。目前基于胶片的阅读系统不适合解释大量的数据。因此，有必要开发新的多层螺旋CT实时容积可视化系统。在临床应用中，非常需要任何方向的实时各向同性MPR。使用MPR/MIP使用各向同性数据，准确的诊断是可能的，而不存在部分容积效应。我们的系统使用通用的基于Windows的计算机和DICOM免费/低价格的软件（Exa Vision ; ZIO），使我们能够有效地利用使用多层螺旋CT在常规临床诊断中获得的体积数据。在4排多层螺旋CT中，每天生成的数据量为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，从服务器传输到阅读工作站的速率为5-6层/秒，该速率并不高。我们的系统在常规诊断中存在一些问题。
