Using a chariot as a patient support system, it becomes possible to obtain consistent radiographic visualization of the hip. The chariot radiographs also allow for a more precise evaluation of the hip at follow-up visits. In most cases subsequent radiographs can be superimposed, differentiating between patient posture and biomechanical characteristics. The consistent patient positions and beam centering facilitate follow-up roentgenography with a higher degree of accuracy. True progression, particularly to a minor degree, can only be assessed with consistently reproducible positions for roentgenographic examinations. The chariot provides roentgenograms at a low cost and is a useful adjunct to diagnostic methods.
使用推车作为患者支撑系统，可以获得髋关节一致的放射影像学图像。推车拍摄的X光片还能在随访时对髋关节进行更精确的评估。在大多数情况下，后续的X光片可以叠加，从而区分患者的姿势和生物力学特征。一致的患者体位和射线束中心定位有助于更准确地进行随访X线检查。真正的病情进展，尤其是轻微程度的进展，只有在放射学检查的体位能够始终如一地重复再现时才能评估。推车以低成本提供X光片，是诊断方法的有用辅助手段。
