- 兽医辐射学 兽医辐射学
- 医疗成像医学成像
- 数字辐射学数字辐射学
背景情况:
- 数字放射学中的图像处理 (IP) 对于提高图像质量和诊断精度至关重要.
- 可适应的IP设置允许根据特定的成像要求和解剖区域进行定制.
- 之前的研究已经探讨了各种IP技术,但它们对马肢X射线图的影响需要进一步调查.
研究的目的:
- 评估不同图像处理设置,特别是灵活噪声控制 (FNC) 和虚拟网格处理 (VGP) 对马体肢体图像质量的影响.
- 在不同的辐射剂量水平下评估这些IP设置的有效性.
- 确定最佳的IP设置,以实现诊断图像质量,同时最大限度地减少马类放射学中的辐射暴露.
主要方法:
- 一项前性分析研究对20个马类尸体肢体样本进行.
- 使用动态可视化II系统获取图像,具有五种不同的IP设置,包括FNC和VGP.
- 图像质量由四名兽医放射学专家使用盲目评分系统评估,评估骨结构可视化和文物感知等标准.
主要成果:
- 虚拟网格处理 (VGP) 在全剂量下改善了骨结构评分,并增强了人工物感知.
- 灵活的噪声控制 (FNC) 有效地抑制了图像噪声,并在50%和25%的辐射剂量下改善了骨结构额定值.
- 临床上可接受的图像质量在FNC的50%剂量下保持,95.8%的评级被认为是足够的或更好的.
结论:
- 根据放射科医生的偏好和特定的临床需求量身定制的个性化图像处理设置,比马类数字放射学的默认设置更好.
- FNC和VGP是优化图像质量的宝贵工具,并使马匹四肢放射学中剂量减少成为可能.
- 进一步的研究可以探索这些先进的IP技术在兽医实践中的长期临床影响和成本效益.

X-ray Imaging
5.5K
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Imaging Studies for Cardiovascular System III: X-Ray
188
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
