THREE DIMENSIONAL COLOR IMAGING

该计划的长期目标是发展化学， 实现彩色三维立体成像。 我们的目标是 计算机输出到光化学聚合事件， 能影响形成逼真的色彩立体清晰 塑料物体，其中输入由CAT扫描提供，以及MRI 扫描等。 该项目利用了立体光刻的原理， 激光引发的光聚合， 在真实的时间中的物体。 该物体是由塑料制成的（通常是 交联的聚丙烯酸酯）逐点、逐层，并且可以 在聚合的真实性中构建尽可能多的独特性 事件和数据将允许。 在实践中，三维物体 从CAD输出产生10 "x 10" x 10 "可以在几个小时内 机器时间使用3D系统技术。 通过可视技术 在我们的实验室中开发的，构建时间大大减少。 在拟议的工作中，我们开发了所需的聚合物化学， 用真实的颜色制作出这样的物品。 在医学成像中 在一些应用中，具有真实的对象将是特别有用的， 作为一个模型，从颜色上看， 通过体内CAT扫描或MRI扫描。 这是一个长期的目标， 工作建议-发展化学，使人们可以产生一个 通过CAT或MRI扫描获得的真实彩色三维模型。

The long range objective of the program is to develop the chemistry to realize three dimensional solid imaging in color. The goal is to couple computer output to a photochemical polymerization event such that one can affect the formation of an authentic color three dimensional clear plastic object wherein the input is provided from a CAT scan, and MRI scan or the like in the time it takes to complete the scan. The project takes advantage of the principles of stereolithography and laser initiated photopolymerization which produces a three dimensional object in real time. The object is produced out of plastic (generally a cross-linked polyacrylate) point by point, layer by layer, and one can build as much uniqueness into it as the trueness of the polymerization event, and the data, will allow. In practice three dimensional objects produced from CAD output 10" x 10" x 10" can be made in a few hours machine time using 3 D systems technology. With visible technology developed in our laboratories, build time is substantially decreased. In the proposed work, we develop the polymer chemistry required to produced such an object in authentic color. In medical imaging applications it would be specifically useful to have an authentic object to work from as a model which looked, on color, as did the area imaged by the CAT scan or MRI scan in vivo. This is the long range goal of the work proposed - to develop the chemistry such that one can produce an authentic, in color, three dimensional model from a CAT or MRI scan.
