Paper Abstract

An additional digital system has been developed in extension with the transillumination system by Dr. A. O. Wist, which captures images onto film by raster scanning, to decrease scanning time and to acquire, store, and display the scanned results in a personal computer with 256 shades of gray. Since only one scan is required for each image, this method can reduce the scanning time of the previous film system by factor of 10. This technique utilizes software to position the laser and to acquire data. While a tooth is being scanned, the analog to digital converter acquires the output voltage from the receiver and stores on the data on the computer's disk drive where afterwards a software program displays the results in super VGA with 256 gray shades on the monitor. The images are then stored as bit mapped images in either a GIFF or PCX format for printing and portability. Several teeth have been scanned and displayed on a 256 gray scale monitor.
