基于CT三维口腔牙图像的滤波技术的应用

Application of filtering technology based on CT 3D dental image

计算机断层技术(CT)的出现,是人类医学史上的一大突破,标志着现代医学正式跨入数字化时代。这种通过不同的人体组织对射线的吸收率不同的原理而显示体内情况的技术便利了医生对病患病情的评估与治疗。CT图像的三维重建是医学影像学中的一个重要领域,同时口腔CT又是使用率最高的领域之一。对口腔CT图像中的软组织的优化可以在成像之后对医生的诊疗起很大的帮助。本文进行各种滤波器对于图像的去噪以及平滑优劣性比对。通过滤波函数参数可视的实时调节,选择最合适的滤波方式及参数,达到CT图像优化的效果。

The advent of computed tomography technique（CT） is a breakthrough of human medical history, marks the modern medicine officially entered the digital age. This through different tissue on radiation absorption rate of different principle and shows the body situation of technolog7 has facilitated the doctor to the patient＇s condition assessment and treatment. CT image 3 d recon- struction is an important field in medical imaging;oral CT is one of the highest utilization rate at tile same time. The optimization of dental CT images of soft tissue can after imaging of great help to the doc, tor＇s diagnosis and treatment. In this paper, the main work includes a variety of filter for image dennising anti smoothing and comparisons. The filtering function parameters can be adjusted in real time to select the most appropriate filtering method and parameters to achieve the effect of CT image optimization.
