不同扫描和处理方式对医学图像细节显示的影响

Impact of Different Scanning and Processing Modes on Medical Image Detail Display

目的:比较不同扫描和处理方式对肝癌图像细节显示的影响,便于临床诊断。方法:选用同一患者的延迟期、动脉期、静脉期和平扫肝癌图像,分别进行插值处理、灰度显示和窗口处理,比较原图和处理后图像的细节变化。结果:同一患者在不同方式下扫描的肝癌图像可以从不同角度和细节展示病变信息,通过对不同时期图像的插值、灰度处理和窗口处理,发现插值技术和窗口技术处理过的图像细节更清晰,诊断更容易。结论:利用3种插值方式及对应的灰度插值都可以改变图像的质量,选择合适的窗位、窗宽能使待观察病变部位的亮度和对比度更适宜,图像更清晰。

Objective To compare the impacts of different scanning and processing modes on liver image＇s detail display. Methods The images for delay period, arterial phase, venous phase and plain scanning of the same patient underwent interpolation processing, grayscale display and window treatment, then the changes of the post-processing images against the original ones were analyzed. Results The images going through interpolation processing and window treatment could give off more details than others. Conclusion Three interpolation modes and corresponding gray interpolations can change the image quality, and the position and width of the window can alter the brightness and contrast of the image.
