[en] Evaluation of track etch detectors is mostly carried out either visually or using specialized image analyzing SW systems. In both cases additional equipment is necessary, involving quality microscope, digital camera and other HW components. In some cases, especially when a method of electrochemical etching is used to reveal tracks, it is possible to use a high resolution scanner and to avoid both tedious visual counting and construction or purchase of complicated and expensive image analyser. In our study we have used the model Epson Perfection 4990 Photo, with resolution 4800 dpi. Irradiated and etched detectors of variable size (typically 15x15 mm, 35x60 mm and 30x120 mm) were evaluated by standard visual method at first and then scanned. Their binary pictures can be easily treated by freely available programs, e.g. Image J. This program offers possibilities to edit the binary picture, e.g. to choose easily surface of interest, determinate precisely its area, erase material defects or scratches, reduce the track overlapping using function watershed etc. Track densities obtained by both method were compared in the range 10 - 5x10³ tr/cm² and very good agreement has been found for track densities within 10 - 3x10³. According to our experience it is possible to evaluate ∼ 80% of total amount of detectors using a scanner. It improves situation especially in some routine measurements, e.g. radon studies
