    • The present disclosure discloses a method of producing an anatomical phantom of an anatomical part having components of different density. The method includes providing a mold of an anatomical part, providing a mold having a size and shape corresponding to a first constituent of the anatomical part. A first liquid is place into the constituent mold and frozen which is placed into the larger anatomical mold and supported in a location corresponding to an actual location of the part in an actual anatomical part. The larger mold is then filled with a second liquid, which forms a gel after a freeze/thaw cycle, to encase the frozen first liquid in the second liquid and the temperature is dropped to freeze the second liquid. The combination is then thawed to produce an anatomical phantom of the anatomical part having a continuous seam between the first constituent part and a remainder of the anatomical part represented by the polyvinyl alcohol based gel. The first and second liquids have a composition such that upon undergoing one freeze thaw cycle, products resulting from the freeze thaw cycle have different densities approximating different constituents of the anatomical part with the second product being a gel encapsulating the first product.
    • 本公开公开了一种产生具有不同密度成分的解剖部分的解剖体模的方法。 该方法包括提供解剖部件的模具,提供具有对应于解剖部件的第一部件的尺寸和形状的模具。 将第一液体放置在构成模具中并冷冻,其被放置在较大的解剖模具中并且被支撑在与实际解剖部件中的部件的实际位置相对应的位置。 然后,较大的模具填充第二液体,其在冷冻/解冻循环之后形成凝胶,以将冷冻的第一液体包裹在第二液体中,并且降温以冷冻第二液体。 然后将组合解冻以产生解剖部位的解剖体模,其在第一组成部分和由聚乙烯醇基凝胶表示的解剖部分的其余部分之间具有连续接缝。 第一和第二液体具有这样的组成,使得在经历一个冻融循环后,由冻融循环产生的产物具有接近解剖部分不同成分的不同密度,第二产物是封装第一产物的凝胶。

    • An exemplary system for manufacturing a decorated polycarbonate sheet can include a mold (102, 202), which has a surface (104, 204) and a three-dimensional pattern (106, 206) formed on the surface (104, 204), such that the three-dimensional pattern (106, 206) resembles a machined metal surface. A substrate (118, 218) can be configured to contact a curable photopolymer (120, 220), such that the curable photopolymer (120, 220) forms a curable layup (122, 222) disposed between the substrate (118, 218) and the mold (102, 202). A light source can be configured to cure the curable layup (122, 222) so as to form a cured layup (128, 228). The mold (102, 202) can be configured to be separated from the cured layup (128, 228), and the cured layup (128, 228) can have a decorative surface texture (108, 208) corresponding with the three-dimensional pattern (106, 206), such that the decorative surface finish mirrors the three-dimensional pattern (106, 206) resembling the machined metal surface.
    • 用于制造装饰的聚碳酸酯片材的示例性系统可以包括具有形成在表面(104,204)上的表面(104,204)和三维图案(106,206)的模具(102,202),这样的 三维图案(106,206)类似于机加工的金属表面。 衬底(118,218)可以被配置为接触可固化光聚合物(120,220),使得可固化光聚合物(120,220)形成设置在衬底(118,218)和 模具(102,202)。 光源可以被配置成固化可固化叠层(122,222),以便形成固化的叠层(128,228)。 模具(102,202)可以构造成与固化的叠层(128,228)分离,并且固化的叠层(128,228)可以具有对应于三维图案的装饰性表面纹理(108,208) (106,206),使得装饰表面光洁度反映类似加工金属表面的三维图案(106,206)。
