项目摘要

The development of the living body substance model high speed framing device by the light molding methed that used CT film. It is that the purpose of this studies develops tha device which can make the living body model simply from CT film.At first, we digitized CT film and converted it into numerical data, and we got possible to make the living body model when seemed not to be got CT data directly from CT device. Then we compared a model made from CT data with this model. As a result, there are some problems by setting of precision and threshold value of image, but this model is very useful for simulation of simple operation.Next, we tried a method to copy 1 slice at a time furthermore.So, (1) We developed original software for image processing, and extracted shape of internal organs in the living body from CT film automatically, and established technology to generate data for transcription.(2) We changed image from CT film to monochrome, and copyed on film that ultraviolet rays transmit. So, we could make a model by exposured 1 slice at a time.In particular, about film for exposure mask, we ware able to confirm that we could utilize extremely cheap materials. But, about a quantity of light and the control of resinous depth to stiffen to transmit film, still many problems.

利用CT胶片光成型法研制了活体实物模型高速分幅装置。本研究的目的是开发一种能够简单地从CT片制作活体模型的装置，首先将CT片数字化并转化为数值数据，使在CT片上无法直接获取CT数据的情况下制作活体模型成为可能。然后，我们比较了一个模型，从CT数据与此模型。因此，虽然在图像的精度和阈值的设定上存在一定的问题，但该模型对于模拟简单的操作是非常有用的。接下来，我们进一步尝试了一次复制1层的方法。因此，（1）开发了原始的图像处理软件，从CT片中自动提取活体内部器官的形状，并建立了转录数据的生成技术。(2)将CT胶片转换为单色，并复制在紫外线透射的胶片上。因此，我们可以一次制作一个模型。特别是关于曝光掩模的胶片，我们可以确认我们可以使用非常便宜的材料。但是，关于透光胶片的光量和曝光深度的控制，还存在许多问题。
