目的 常规胸片上 ,在不改变投照条件下 ,使脊柱、纵隔、心后肺内占位病灶和两侧肺野内细小病变 ,均能清晰地显示在同一张照片上。方法 通过对现有增感屏的增感物质在布局上加以改变和技术处理 ,即中央部分涂成高速增感物质 ,两侧涂成中速增感物质。结果 用新屏对 7例患者进行投照 ,其结果是脊柱、纵隔、心后肺内占位病灶均较清晰地显示在同一张照片上 ,基本达到预期目的。结论 在常规胸片上 ,新型宽域X线增感屏能给X线诊断提供更多、更清晰、层次更加丰富的影像信息
Objectives Conventional chest radiography, without changing the projection conditions, so that the spine, mediastinum, posterior lung space occupying lesions and small lesions in both lung fields, can be clearly displayed in the same photo. Methods By changing and disposing of the sensitizing materials of the existing sensitizing screens, the central part is coated with high-speed sensitizing substances and the two sides are coated with medium-speed sensitizing substances. Results Screening 7 patients with a new screen, the result is spine, mediastinum, posterior heart lesions within the lung lesions were clearly displayed in the same photo, the basic achieve the desired goal. Conclusions On conventional chest radiographs, a novel wide-area X-ray intensifier screen provides more, clearer, more layered image information for X-ray diagnosis
