摘要

To obtain 3D ultrasound image, traditionally, a ID ultrasound transducer and an orientation system are used to get a series of 2D images and their positions. From these 2D images and position information, a 3D image is reconstructed. In this paper, the accuracy of the 3D image is determined by the accuracy of the position information, furthermore it affects the result of the measure from the 3D image. When in rotational scanning mode, the reconstructed 3D image is sensitive to the calibration parameters, including the orientation difference as well as the offset between the central line of each 2D US image and the rotational axis. To address this type of effects, we developed a 3D reconstruction technique considering the calibration uncertainty by building a transformation model with a 360 degrees scanning, and an accurate 3D reconstruction with calibration uncertainty is achieved. The experiments with both synthetic and scanning phantom data demonstrated the feasibility of our approach.
