- 医学成像分析 医学成像分析
- 生物机械工程 生物机械工程
背景情况:
- 骨质疏松症经常导致衰弱的脊椎骨折.
- 通过DXA的骨矿物质密度 (BMD) 是标准的,但不足以预测脊椎骨折.
- 微结构成像可以改善骨折风险评估.
研究的目的:
- 评估数字图解合成 (DTS) 衍生的脊椎微观结构和尺寸指标是否可以区分患有和没有脊椎骨折的患者.
- 评估DTS参数在体内对骨折歧视的实用性.
主要方法:
- 研究了93名患有/没有脊椎骨折的绝经后妇女.

Computed Tomography

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...

X-ray Imaging

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...
