THREE DIMENSIONAL COLOR IMAGING

该计划的长期目标是将化学发展到 实现彩色立体三维成像。我们的目标是联手 计算机输出到光化学聚合事件，使得一个 可以影响形成原汁原味的立体清晰色彩 其中从CAT扫描提供输入的塑料物体，以及MRI 在完成扫描所需的时间内进行扫描或类似操作。 该项目利用了立体平版印刷的原理和 激光引发的光聚合反应产生的三维 实时显示对象。该对象是由塑料(通常是 交联型聚丙烯酸酯)逐点、逐层地，一个可以 它的独特性与聚合的真实性一样多 事件和数据，将允许。在实践中，三维物体 由CAD输出生成的10“x 10”x 10“可在几小时内制作完成 机器时间采用3D系统技术.使用可视技术 在我们的实验室中开发，建造时间大大减少。 在拟议的工作中，我们开发了所需的聚合物化学 用原汁原味的颜色制作了这样一个物体。在医学成像方面 应用程序拥有可信的对象将特别有用 以模特的身份工作，在颜色上看起来，就像所拍摄的地区一样 在活体进行CAT扫描或MRI扫描。这是我们的远景目标 建议的工作--发展化学，使人们能够产生 来自CAT或MRI扫描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.
