Holographic Viewing of Neuro-images

我们尝试将全息显示技术引入神经外科诊断，以集中提高神经外科疾病的治疗水平。主要目的是开发新的方法来观察和理解各种神经图像的三维和/或动态的方式，这往往是必要的分析获得的神经图像检查l。我们感谢收到赠款-和从教育部促进我们的研究如下：从1986年到1987年，我们尝试了两种技术，即1）多重断层全息术（MT HLG）和2）柱面多重全息术（MP Hlg）。在一张全息胶片上成像。在专门设计的全息光学系统下，利用激光束的光学相干性，将原始神经图像作为不可见的相干条纹进行高速缓存。这种全息图可以在光学相干光波如激光的作用下再现，这种光最初用于重建。有了补助金，我们对三例颅内肿瘤的MRCT进行了全息成像研究，与传统的立体摄影相比，我们能够对这些MRCT进行三维观察，其效果更为自然。本文设计了柱面多重全息摄影系统，用于观察颅内动脉瘤的旋转电影血管造影图像。利用我们的技术，能够分析巨大动脉瘤与邻近重要脑血管的关系。这使我们能够客观地做出明确的诊断以获得最佳治疗。如本手册所示，1）MT HLG的研究已经升华，2）MP HLG的研究正在准备出版。

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.
