摘要
目的分析多层螺旋CT图像伪影的影响因素,探讨处理方法,提高图像质量。方法回顾分析我院CT图像伪影的形成和特点,以及处理方法。结果多层螺旋CT图像伪影种类繁多,表现多样,但多能正确识别,选择正确的扫描方法和参数,可以减少伪影的产生。结论正确认识多层螺旋CT图像伪影产生的原理和处理措施,可以提高CT图像质量,有利于疾病的CT诊断,提高准确性。
Objective Analysis of multi-slice CT image artifact of the influencing factors, exploring ways to improve the image quality. Methods Retrospective analysis of CT images in our hospital the formation of artifacts and features, as well as treatment. Results The multi-slice CI＂ image a wide range of artifacts, the performance of diversity, but to correctly identify and select the correct scanning methods and parameters can be generated to reduce the artifacts. Conclusion The correct understanding of multi- slice CT image artifacts arising from the principle and deal with measures to improve the quality of CT images, CT is conducive to disease diagnosis, improve accuracy.
