Evaluation of an Acoustical X-Y Digitizer for Use in Biomedical Data Reduction Tasks.
Abstract
Air Force biomedical data are often obtained in hard copy, graphic, or pictorial form. Manual data reduction is laborious and time consuming. The work reported here was directed at the development of methods for utilizing a new principle (acoustic ranging) for retrieving (digitizing) X-Y coordinate values from strip charts, graphs, X-ray photographs, or drawings. Included are the results of a statistical study designed to assess the resolution, precision, bias, and linearity of the system. These results verify that the quality of this digitizing process is more than adequate for use on most biomedical applications encountered at the School.
