Application of Adaptive Enhancement Means in Head and Neck CR Image

Abstract:

Digital CR of head and neck overcomes the disadvantage of regular X-ray radiography, which can not reveal bone and soft tissue position deficiency in one exposing, and reduces the X-ray radiation dose. Meanwhile, various factors cause the decline of image quality, and images must be enhanced in order to meet demands of doctor's clinical diagnosis. The general enhancement algorithms don’t consider body's structure differences and density characteristics. A new adaptive CR enhancement algorithm was proposed in this article, and head and neck CR images were processed with this method and compared with linear unsharp masking method. The experiment proves that the details of CR image enhanced were abundant and enhanced CR image had good visual effect, SNR was high, as well as detail variance /background variance (DV/BV) indicating that this algorithm is suitable for head and neck CR medical images
