抄録
Our study was carried out to compare and evaluate two types of grids(single and cross types)for the removal of scattered X-rays exclusive to mammography in an ACR-specified 156 model phantom using fuzzy measure theory (fuzzy measure and its fuzzy integration). When three simulated shadows of the breast phantom (fibrous, calcified, and tumor) were integrated, the cross grid (Gc) showed a slightly higher evaluation value than the single grid (Gs). In addition, when two shadows were combined or each shadow was alone, the Gc was evaluated as 2% or 3% higher. It is difficult to determine the physical properties of a grid for removal of scattered X-rays exclusive to the breast considering the structure of equipment, but if a visual and subjective evaluation is quantitatively conducted by applying fuzzy kinetics, comparison and evaluation can be carried out.
