吸收系数

The basic theory of this design is The Lambert Laws that the logarithm of the radio of the energy of a primal ray and the energy after this ray though a equable material is direct proportion with the thickness of the equable material,and so do the coefficient that the equable material absorpt with the ray.

For image enhancement of digital radiography, the traditional processing methods originally used in various tomographic imaging modalities aren't available for enhancing the digital radiographic images, especially for the digital chest images because of the wide dynamic range of information between x-ray emerging from the heavily attenuated mediastinum (heart, spine, aorta, and other central features on the radiography) and subdiaphragmatic area and those that have passed through the air- filled lung.

对于数字放射图象的增强，原先用于CT等各种断层医学数字图象的传统处理方法并不能获得满意的效果，尤其对于数字放射胸片图象。其原因在于放射胸片图象具有相对较宽的信息动态范围，从具有非常大吸收系数的纵隔区（放射上指脊柱，心脏，主动脉）及下隔膜区到X线极易穿透的充满空气的肺部。
