Because of their high impact and sharpness, we believe that holograms make better teaching tools than conventional images, and one day will be common in medical texts and journals. To be maximally effective, often there must be labels or arrows within the images. Ideally these should be applied when the master is made, but they can be affixed to the image plane copy at a later date. Because of the constraints of the holographic medium, lacking a pulsed laser, one is limited to making images of rigid objects such as bones and anatomical models, though the technique of plastination makes tissue specimens solid enough to make acceptable images with continuous beam lasers. 1 . Putting the label in the master Using continuous beam lasers, the labels must be rigidly affixed to the platform holding the specimen. If the object is inflexible—such as a bone— the label or arrow can be glued directly to it. Reusable adhesives (such as FUN TAK) work reasonably well , though permanent glues are better. If the specimen is plastinated tissue—which is somewhat elastic—the label must be affixed to the base which is fastened to the table. 2. Adding a marker to an image plane copy. If one already has a hologram and wishes to put a label on it, press-on letters and arrows can be applied and burnished to the glass plate. The characters should be affixed to the front or non-emulsion side before the back side is painted black. Once it is painted it is virtually impossible to see where in the image one is putting the letters.
