X Ray Image Contrast. The chest x ray is a long scale low contrast image. As the photon energy decreases the differential attenuation between the lesion and surrounding tissues increases.
The chest x ray is a long scale low contrast image figure 1. X ray enhancement based on component attenuation contrast adjustment and image fusion abstract. X rays with higher kvp can penetrate deeper into materials.
We open with some of the basic notions of x ray imaging including the vacuum wave equations and the physical meaning of the intensity and phase of complex scalar fields.
However due to an x ray s low contrast and low dynamic range important aspects such as organs bones and nodules become difficult to identify. The hand x ray is a short scale high contrast image. Drag here to reorder. As the photon energy decreases the differential attenuation between the lesion and surrounding tissues increases.
