- 整形外科手术 整形外科手术
- 放射学 放射学是一门学科.
- 生物医学工程 生物医学工程
背景情况:
- 边缘性形形是由20°至25°之间的横向中心-边缘角度 (LCEA) 定义的.
- 之前的研究报告了普通放射性评估中的变异性,但3D部形态变异性不太了解.
研究的目的:
- 通过使用低剂量CT,研究症状边缘性形质症中3D部形态的变异性.
- 为了确定平面放射学参数和3D部覆盖之间的相关性.
主要方法:

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...

2.6K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...
