Image enhancement by digital-analog filtration. II. Tests of filters. 1979

A Hemmingsson, and B Jung, and H Lundqvist, and A Strömlid

The function of a device for frequency filtration of roentgenograms with digital filters has been tested with the use of different filters. The image was altered in the expected way, which means that the device is suitable for investigating the possibilities of different filters to improve the diagnostic ability. The results of the tests indicate that improvement should be achieved by low-pass filtration.
