    • A selectively demetallized metal film is provided in which the metal film has different amounts of metal removed in different areas to provide a film having a graduated optical density from one area to another. The amount of metal present in the film can vary gradually and continuously or in stages resulting in a series of bands or patches. Each portion of the film appears uniform, homogeneous and uninterrupted to the unaided eye. The product is produced by providing a substrate such as plastic film having a thin semiconductive metal film coated thereon. Different amounts of the metal are removed from the film in different areas, preferably by exposing the metal film in different areas to different amounts of an etchant which can be provided in the form of minute droplets of one size in one area and of a different size in a different area. The etchant can be applied by halftone printing as variably sized dots on uniformly fixed centers with larger dots of etchant applied in some areas than in others to remove a greater amount of the metal.
    • 提供了选择性脱金属的金属膜,其中金属膜在不同的区域中去除了不同量的金属,以提供具有从一个区域到另一个区域的刻度光密度的膜。 存在于膜中的金属的量可以逐渐地和连续地或分阶段地变化,从而产生一系列带或块。 胶片的每一部分均匀,均匀且不间断地连接到肉眼。 该产品通过提供其上涂覆有薄的半导体金属膜的基材例如塑料膜来制造。 不同量的金属在不同的区域中从膜中去除,优选通过将不同区域中的金属膜暴露于不同量的蚀刻剂,其可以以一个尺寸的微小液滴的形式在一个区域中提供并且具有不同的尺寸 在不同的地区。 蚀刻剂可以通过半色调打印作为可变尺寸的点在均匀固定的中心上施加,在一些区域中施加较大的蚀刻剂点比在其它区域更大以除去更大量的金属。

    • A method and associated apparatus for imaging an oxygen-containing, internal body portion of a host animal which comprises: (a) adding to a body fluid of the host animal a phosphorescent composition (e.g., zinc verdin or a metal porphyrin compound) compatible with said body fluid, the phosphorescence of said composition being quenchable with oxygen in said body portion; (b) irradiating said body portion with a pulse of light at a wavelength and for a time sufficient to effect phosphorescence of said composition to be emitted as light from said body portion; (c) scanning across said body portion to measure the decay of said emitted phosphorescence across said body portion; (d) relating any variations in said decay measured across said body portion to variations in structure of said body portion based on oxygen contained by the body portion; and displaying an image of said body portion.
    • 一种用于成像宿主动物的含氧内体部分的方法和相关装置,其包括:(a)向宿主动物的体液中加入磷光组合物(例如,锌丝蛋白或金属卟啉化合物),其与 所述体液,所述组合物的磷光在所述主体部分中用氧气淬火; (b)用波长长达一定时间的光脉冲照射所述主体部分,以使所述组合物的磷光作为来自所述主体部分的光发射; (c)跨所述主体部分扫描以测量穿过所述主体部分的所述发射的磷光的衰减; (d)将基于所述主体部分测量的所述衰减中的任何变化与基于所述主体部分所含的氧的所述主体部分的结构变化相关联; 以及显示所述主体部分的图像。
