1.ObjectivesPurpose of this study is to develop holographic 3D display system for volume data using a computer-generated hologram technique and to evaluate the 3D images.2.Results of research(1)We succeeded in displaying a three-dimensional image by a hologram of volume data and were able to realize a large-sized hologram in comparison with before. New knowledge was provided through this development technically. In addition, I clarified the effectiveness of the method by the large-size holograms that are able to see by naked eyes. However, on the other hand, the problems such as quantization and calculation algorithm, which we must study in future, became clear newly. The results of research were able to become a touchstone for practical use.(2)We have developed a total 3D displaying system for medical images : (i)volume data are scanned at Tokyo Metropolitan Univ., (ii)transmitted to Hokkaido Univ. though the internet, (iii)calculated for hologram data, (iv)transmitted to Kanasai Univ., and (v)printed on photo plates.(3)In addition, in the field of each study, we were able to achieve the following results :(i)New rendering algorithms for computer-generated hologram that are useful for realistic imaging,(ii)New segmentation methods for organs and image processing methods,(iii)A new fringe printer that is large size and high resolution,(iv)New 3D image compression metods.

1.研究目的本研究的目的是利用计算全息技术开发体数据的全息三维显示系统，并对三维图像进行评价。2.研究结果（1）我们成功地用体数据的全息图显示三维图像，与以前相比，我们能够实现大尺寸的全息图。通过技术上的发展提供了新的知识。此外，我阐明了该方法的有效性，通过大尺寸的全息图，可以看到肉眼。然而，另一方面，量化和计算算法等问题，我们必须在未来的研究，成为明确的新。研究结果能够成为实际应用的试金石。(2)We已经开发了用于医学图像的全3D显示系统：（i）在东京首都大学扫描体数据，（ii）通过互联网传输到北海道大学，（iii）计算全息数据，（iv）传输到Kanasai大学，及（v）印在相片版上。(3)In此外，在每个研究领域，我们能够实现以下结果：（i）新的绘制算法的计算机生成的全息图，是有用的逼真的成像，（ii）新的分割方法的器官和图像处理方法，（iii）一个新的条纹打印机，是大尺寸和高分辨率，（iv）新的三维图像压缩方法。
