乳腺模体(用于 X射线机乳腺机性能的检测)

朝阳生物被广大客户称为优质的乳腺模体厂家,质量有保证,乳腺模体价格性价比高。 乳腺机性能检测模体 由主模体和衰减模体组成,用于 X射线机乳腺机性能的检测,可检测空间分辨力、低对比度分辨力、自动曝光控制功能、胶片光密度、射野与支撑台台边的偏差等技术指标。

测量时,将 乳腺模体 放在支撑台上曝光,读取图像上高对比分辨力的值是否满足技术要求;在自动曝光条件下曝光,读取图像所能显示的钻孔深度,测量乳腺机的低对比度分辨力;测量距胸侧边 4cm处照片长轴中心的光密度;极限值ed光密度应为1.4D~1.8D; 把PMMA板分别组为20mm、40mm、60mm厚度,放在支撑台上曝光,检测乳腺机的自动曝光控制功能;调整光野与胸侧支撑台边沿对齐,进行曝光后观察图像上钢珠的个数及位置,测量胸壁侧射野与乳房支撑台台边的偏差。
