The utility model also discloses a static X ray photography light sensitive plate cassette including a box, wherein the box comprises a bottom surface, a top surface, a left side surface, a right side surface, a rear side surface and a cassette door located on the front end of the box,...
The next thing he found out was that if he put his hands between the rays and a photographic plate(感光板) the rays would print a shadow of the bone framework(骨架)of his hands on the plate. In fact the rays could pass as easily through the fleshy part of his hand as through the ...
Although various recording devices85, 86 such as an imaging plate87, 88 have been proposed for radiation sensitive specimens, the resolution of these devices is generally inferior to that of photographic emulsion. From the view point of cost performance, photographic films are recommended at present...
The outer surface of a flat metal plate with a central aperture, adapts the cone of the X-ray tube so that the aperture of the plate lies symmetrically within the cone. The smaller base of O the shield is mounted on the inner surface of the plate so that the aperture is centrally ...
Many modifications and improvements have been offered during the past 40 years, all of which have been aimed at higher resolution. Some investigators, therefore, advocate the use of nuclear emulsion instead of X-ray or other photographic emulsions. The drawback of having to view the photographic ...
white image. Because they were still disproportionately sensitive to blue, the use of a yellow filter and a consequently longer exposure time were required in order to make full use of their extended sensitivity. In 1894 the Lumière Brothers introduced their Lumière Panchromatic plate, which was ...
The final example is the result of the Trip 35’s lens focus click-stop at 3 metres and the Metz yellow button selected. This distance would accommodate the majority of groups of people being photographed. Gus, by this time, had migrated to the lounge, this being one of his favourite sle...
[0008] As a result of an intensive investigation in consideration of the above-mentioned objects, the present inventors have discovered that the foregoing objects are accomplished by an emulsion containing silver halide grains in which the proportion of metal gold among gold existing on the part of...
nodes 53 and 54 of the rotation of the filter 55, the plate 56 is smoothly supported, the photo is taken from the photo original 9, the emulsion 57 is sensitive, the salt-forming nodes 58 and 59 of the filter 60 of the photomultiplier 11. If ...
Accordingly, it is an object and advantage of the invention to provide a simple cassette, for an x-ray phosphor film plate of the kind used in computed radiography, which can include an x-ray grid and has a photographic element assembly, that is removable from a shell by a hooked extracto...
