Digital slot scanning is a relatively new technology that has been used for imaging of pediatric orthopedic conditions such as scoliosis and leg-length discrepancies. This article will review the clinical applications, advantages, and unique artifacts of this new technology.
Upright biplanar slot scanners acquire high-resolution radiographs simultaneously in two orthogonal planes with reduced radiation dose. Other advantages include a more physiologic weightbearing imaging position, improved Cobb angle measurements, and 3D modeling.
数字狭缝扫描是一项相对较新的技术，已用于诸如脊柱侧弯和腿长差异等小儿骨科疾病的成像。本文将综述这项新技术的临床应用、优势和独特伪影。
直立双平面狭缝扫描仪可在两个相互垂直的平面上同时获取高分辨率的X线片，且辐射剂量降低。其他优势包括更符合生理状态的负重成像位置、改进的Cobb角测量以及三维建模。
