Abstract

This paper describes the results of the comparison of 5 film digitizers designed for medical application to find an appropriate film digitizer for a project involving display of mammograms on a high performance CRT. Two of the digitizers were of the laser-scanning type while 3 were based on CCD technology. The comparison included estimates of linearity, uniformity, signal-to-noise ratio and spatial resolution in terms of the Modulation Transfer Function (MTF). The digitizers investigated show vastly different results. No system excelled in all performance parameters. A laser scanning digitizer was chosen for the planned display project because (1) it had the best linearity (down to OD 4); (2) it had the highest SNR at OD 4; (3) it had a comparatively good MTF.
