产品介绍
深圳市湾边贸易公司CIRS 016B 高对比度分辨率模体详细描述 The CIRS Model 016B incorporates a 17.5 micron thick gold-nickel alloy bar pattern. Each bar pattern is positioned at 90 degrees to allow assessment of resolution perpendicular and parallel to anode-cathode axis in just one exposure! The 016B high resolution target has 18 segments from 5 lp to 28 lp/mm. The target is equivalent to 25 microns of lead or 2.6 mm of aluminum at 20 keV. The bar pattern is permanently embedded in a thin acrylic wafer to protect it from wear or damage. The phantom body is available in BR12 or BR50/50. It enables consistent, reproducible positioning of the bar pattern at 4.5 cm above the breast support plate and 1 cm from the chest wall, centered laterally (as recommended by the American College of Radiology).
CIRS 016B 高对比度分辨率模体 - 高28线对/ mm
CIRS 016B 高对比度分辨率模体采用17.5微米厚的金镍合金棒材图案。每个条形图案都定位在90度,以便在一次曝光中评估垂直和平行于阳 - 阴轴的分辨率!CIRS 016B高分辨率目标有18个段,从5 lp到28 lp / mm。目标相当于20keV的25微米铅或2.6毫米铝。
条形图案嵌入薄的丙烯酸晶圆中,以防止磨损或损坏。
