Abstract
Objective. To evaluate the possibility of using the «SyGrid» digital image processing program for mammography (software grid) instead of the traditional movable grid.
Materials and methods. On the basis of the mammograph Mammo-4MT-Plus (JSC «MTL», Moscow), the «SyGrid» software grid was compared with a standard movable grid. At the laboratory stage, CDMAM and CIRS 010D phantoms were used. At the clinical stage, doses were compared in samples of 1063 studies with a physical grid and 1132 studies with a software grid. To compare the image quality, 200 random studies from each sample were independently blindly evaluated by three radiologists.
Results. At equal doses, the quality metrics calculated with CDMAM and CIRS 010D phantoms with a software grid were no lower than with a physical grid. Radiologists, on average, rated the quality of images with a software grid significantly higher than with a physical one. The average dose in the sample with a software grid was 22 % lower than in the sample with a physical grid.
Conclusion. The «SyGrid» software grid can be used instead of a movable physical grid for mammography.
