Abstract


In recent years, with the development of computer technology and digital technology , digital X-ray photography technology to replace the screen - dispensing systems for clinical diagnosis , including computed radiography and digital radiography , digital X-ray photography . How to evaluate the quality of these radiation imaging , to become a very important issue . Therefore it is necessary to establish an objective and scientific evaluation of image quality , in order to facilitate better used in clinical diagnosis . First, the image quality evaluation methods are reviewed , and radiography new modulation transfer function evaluation method based on the interest in the human visual evaluation method and evaluation method based on wavelet transform , and the traditional quality evaluation method the results of these methods were compared , the experiment proved superior to the conventional image evaluation method , and is consistent with the human visual perception . Because the need for large-scale data analysis and processing , medical image processing all image data and experimental examples and the results are used to achieve Matlab language software program .
