Zusammenfassung:Embodiments include systems and or methods directed to ultrasound calibration, real-time C-mode approaches, calibration using a plate target, a ball-and-socket scan mechanism, a spherical spiral path scan mechanism, and a wireless disposable laryngoscope. 本发明公开种校正超音波扫描器的方法,通过旋转轴及垂直于轴的θ轴,其包含有:将换能器沿轴旋转并收集在扫描平面上来自目标反射面上的第数据;根据第数据计算第最大峰值强度的角度;将换能器沿θ轴旋转180°;将换能器沿轴旋转并收集在相同扫描平面上来自相同目标反射面的第二数据;根据第二数据计算出第二最大峰值强度的角度;将两最大峰值强度的角度相减得差值。本发明可根据此差值以校正超音波扫描器,不仅可以省略现有使用水箱或额外超音波目标物的校正手法,同时可避免因视差所造成的校正误差。
