Holographic Viewing of Neuro-images

我们尝试将全息显示技术引入神经外科的诊断中，以期提高神经外科疾病的治疗水平。主要目的是发展一种新的方法，以三维和/或动态的方式观察和理解各种神经图像，这通常是分析所获得的神经图像检查所必需的。我们感谢从教育部获得的资助，并使我们的研究如下：从1986年到1987年，我们尝试了两种技术，即1)多断层全息术(MT HLG)和2)柱面多重全息术(MP HLG)。我们的研究的原理是在一张全息胶片上记录多个连续的神经图像。在特殊设计的全息光学系统下，利用激光的光学相干性，以高速缓存的原始神经图像作为不可见的干涉条纹。这种全息图可以在激光等光学相干光波下观察。1)多层析全息术；在资助下，我们研究了对三例颅内肿瘤的MRCT进行全息化。与传统的体视图相比，我们能够以更自然的方式对这些MRCT进行三维全息观察。2)柱面多路全息术被设计用于观察一系列旋转电影血管全息图，用于观察其他情况下的旋转电影血管图像。利用我们的技术，我们能够分析巨大动脉瘤与邻近重要脑血管的关系。这使得我们能够客观地对最佳治疗做出明确的诊断。正如这本小册子所示，对MT HLG的研究已经转载，对MP HLG的研究正在准备出版中。

We have attempted to introduce holographic display technology into neurosurgical diagnosis in order to focillitate improvement of treatment in neurosurgical disorders. Main purpose is to develop new method of observation and understanding of various neuro-images in three dimensional and/or dynamic fashions, which is often necessary to analyse abtained neuro-image examinationsl.We appreciate receirring the grant-and from the Ministry of Education which facillitated our study as follows:From 1986 to 1987, we have tried tow techniques namely 1) Multi-tomogram holography (MT HLG) and 2) Cylindrical multiplex holography (MP Hlg).Principle of our study is to record multiple serial neuro-images in one single holographic film. under the specially designed holographic optical system using laser beam becamus of the optical cohercncy and in the way that the cach original neuro-image as the invisible interferent fringe. This hologram can be reviewed under the optically coherent light waves such us the laser, originally used for reconstruction.1) Multi-tomogram holography; with the grant-aid, we studied to hologramize MRCT of three cases of intracranial tumors.We were able to make holographic abservation of these MRCTs in 3-dimensional observation in much more natural fashion in comparision with the conventional stereogramas.2) Cylindrical multiplex holography is designed and used for observation of series of rotational cine-angiographic pictures in the case of undiagnosed intracranial aneurysm otherwise. Ith our technique, relationship of a huge aneurysm and neighborhood important cerebral blood vessels were able to be analysed. This leads us to make a definite diagnosis for the best treatment objectively. The study of 1) MT HLG has been sublished and the study of 2) MP HLG is in preparation of publication as this pamphlet indicates.
