Résumé
Objective To assess the examinational value of tissue equalization (TE)technique in DR thoracolumbar vertebral body photography. Methods 48 cases were reformed using the conventional DR method in the thoracolumbar vertebral body photography,compared with the TE technique in DR thoracolumbar vertebral body photography. Results The details in different thickness area of body could be revealed clearly in the same image produced by TE technique. The visualization of image details could be obviously improved by using the TE technique. Conclusion It is important to apply the TE technique in DR thoracolumbar vertebral body photography.
Résumé
Objective To investigate the advantages of DR images produced by tissue equalization(TE)technique in chest digital radiography(DR) compared with standard technique.Methods 100 images collected from DR chest images taken in our hospital in May,2003 were processed by TE technique and compare with standard DR images.Results The details in different thickness area of body could be revealed clearly in the same image produced by TE technique,while the display parameters should be adjusted repeatedly to reveal the details in standard chest digital radiography.Conclusion The visualization of image details can be obviously improved by using the TE technique and other details are not lossed.
Résumé
Objective To study the applied value of unified image enhancement(IE) and tissue equalization(TE) that the two kinds post-processing functions in the diagnosis of patella fracture. Methods The images of knee joint anterior-posterior position of fifty patella fracture patients were taken. The acquired images were processed with IE and TE, and then the im- ages were divided into pre-treatment group and post-treatment group. Results The post-treatment group of patella imaging have markedly improved, and the statistics analysis have significance difference(P
