Conversion of 35 mm text slides into PowerPoint using direct optical character recognition technology.Electronic presentations are now the preferred method of presenting information at national and regional radiological meetings. Many radiologists have large collections of lectures based on 35 mm slides. Conversion of radiographs and photographs to electronic images is straightforward and can be done by direct photography, photography of projected images, or scanning with a dedicated 35mm device or a flatbed scanner A scanner that provides a flat, glass surface to hold pages of paper, books and other objects for scanning. The scan head is moved under the glass across the page. Sheet feeders are usually optionally available that allow multiple sheets to be fed automatically. . Conversion of electronic images of text slides to PowerPoint requires an extra step for best results: An optical character recognition optical character recognition (OCR), method for the machine-reading of typeset, typed, and, in some cases, hand-printed letters, numbers, and symbols using optical sensing and a computer. program is used to convert the pictures of the words into code that can be recognized by computer word processing word processing, use of a computer program or a dedicated hardware and software package to write, edit, format, and print a document. Text is most commonly entered using a keyboard similar to a typewriter's, although handwritten input (see pen-based computer) and programs, including PowerPoint. Text slides are of first generation quality, without artifacts artifacts see specimen artifacts. or copy degradation. Text can be changed, revised, updated, and corrected. Using this method, the full features of PowerPoint can be used to create solid, compelling programs. W. Mel Flowers, Jr, George T. Vanderslice, Richard F. Brown, Renea K. Hays, and Anthony F.
