我们提出了一种新的范例进行二维扫描称为双光束手动驱动失真校正成像（DMDI）。DMDI通过用两个空间上分离的光束对同一物体成像来操作，所述光束在一个维度上被快速地机械扫描，而沿第二维度沿着较慢的手动致动。两个成像通道之间的共同特征的配准允许图像的重新映射以校正由于手动致动引起的失真。我们使用4.7 mm OD旋转扫描双束微马达导管（DBMC）演示DMDI。DBMC需要通过对图案化体模成像来对射束路径进行简单的一次性校准。DMDI允许DBMC的非均匀轴向速度和旋转运动的失真校正。我们展示了这种技术的实用性，通过演示正面OCT图像失真校正手动扫描棋盘模型和指纹扫描。
We present a new paradigm for performing two-dimensional scanning called dual-beam manually-actuated distortion-corrected imaging (DMDI). DMDI operates by imaging the same object with two spatially-separated beams that are being mechanically scanned rapidly in one dimension with slower manual actuation along a second dimension. Registration of common features between the two imaging channels allows remapping of the images to correct for distortions due to manual actuation. We demonstrate DMDI using a 4.7 mm OD rotationally scanning dual-beam micromotor catheter (DBMC). The DBMC requires a simple, one-time calibration of the beam paths by imaging a patterned phantom. DMDI allows for distortion correction of non-uniform axial speed and rotational motion of the DBMC. We show the utility of this technique by demonstrating en face OCT image distortion correction of a manually-scanned checkerboard phantom and fingerprint scan.
