Paper Abstract

A collimated transillumination system has been developed for the detection of small lesions in thick tissues. The test object is raster scanned by a collimated light beam and a synchronous in-line post collimated receiver. The images are recorded either in analog form to a film using a light emitting diode, or stored digitally in a microcomputer and displayed by a 256 gray shade monitor. Tests show that the system can achieve high resolution in detecting small details in images of whole teeth, live mice, breast sections, and bones in the regular operating mode. The resolution can be increased by using a newly developed high resolution method and/or by digitizing the image. In addition, different types of details can be separated from each other by using different wavelengths of light.
