This study was designed the band material in order to reduce the exposure pressure of the breast and the material was measured of Radiolucent and radiation properties with a radiation materials of PC, PMMA, Carbon. Also the image quality by image analysis to obtain the following results are below:
Unfors Xi dosimetry using radiation transmittance when the results of 8.353m㏉ is measured after re-moval of the cuff, the PC 6.308m㏉, PMMA 6.223m㏉, Carbon 7.218m㏉ were measured respectively. Semi-layer PC 0.375㎜Al, PMMA 0.370㎜Al, with Carbon 0.360㎜Al Carbon, PC, PMMA was higher radiation properties and transparency in order.
nLight / OSL NanoDotTM dosimeter was used in the cuff and then removed by placing the dosimeter measured results center on 1.143m㏉, at the edge 12.56m㏉, on the central PC 8.990m㏉, at the edge 10.291m㏉, PMMA center on 8.391m㏉ , the edge 9.654m㏉, on Carbon center 9.581m㏉, 11.313 m㏉ were measured at the edge of Carbon, PC, PMMA showed a high permeability in order.
Image Pixel average J is then removed from the cuff 976.655, PC 831.032, PMMA 819.069, Carbon 897.118 Carbon, PC, PMMA was measured by high order.
