概括
运动显著影响圆束计算机断层扫描 (CBCT) 脊椎骨分析,特别是在10度或更高的温度下. CALM®算法可以减少运动工件,但它的有效性各不相同,需要仔细解释碎形维度 (FD) 结果.
科学领域:
- 牙科成像和诊断牙科成像和诊断
- 生物医学工程 生物医学工程
- 放射学 放射学是一门学科.
背景情况:
- 圆束计算机断层扫描 (CBCT) 对于牙科成像至关重要.
- 运动工件可以降低CBCT图像质量,并影响定量分析.
- 断层维度 (FD) 分析用于评估椎骨结构.
研究的目的:
- 评估CALM®运动工件减少算法的有效性.
- 评估其对减少CBCT图像中运动诱导的模糊度的影响.
- 为了分析其对骨维度 (FD) 分析的影响.
主要方法:
- 使用Planmeca ProMax 3D®在各种运动条件下 (5,10,15度) 扫描人类下,使用和不使用CALM®.
- 每次扫描的五个感兴趣区域 (ROI) 被选择用于FD分析,不包括牙根和皮质骨.
- 用Image-J 1.53软件使用盒子计数方法计算FD.
主要成果:
- 5度的运动对FD分析没有显著影响.
- 10度及以上的运动导致FD值的统计学上显著差异和波动.
- 降低的FD值与增加的运动模糊性相关;CALM®部分抵消了这种效应,在不同位置和运动程度上具有不同的有效性.
结论:

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
