Research Abstract

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.
