论文摘要
对于X射线断层扫描的新对准解决方案的最新建议，虚拟对齐方法（VAM）允许使用更准确的方法来删除可能限制重建图像的分辨率和清晰度的可能误差。在牙科领域，扫描过程中患者的运动是阻碍最终重建图像质量的主要因素之一。在这里，患者的运动是人为地给予投影图像集的，并使用Sinogram进行了新提出的算法，并将固定点应用于牙齿样品，以将重建图像与实际投影图像集进行比较。新的对准方法通过将错误余量降低到几微米，显示出令人鼓舞的结果，这将允许以准确性和精度生产高质量的牙齿假体。我们希望可以进一步研究新提出的对准方法，以更容易地应用于牙科申请，为患者提供更好的质量图像，以更准确地诊断和假体。
The recent proposal of a new alignment solution for X-ray tomography, Virtual alignment method (VAM) allowed a more accurate method to remove the possible errors that limit the resolution and clarity of the reconstructed image. In the field of dentistry, the movement of patients during the scanning poses as one of the major factors hindering the final reconstructed image quality. Here, the patient's movement was artificially given to the projection image set and the newly proposed algorithm using the sinogram and the fixed point was applied to the tooth sample to compare the reconstruction image to the actual projection image set. The new alignment method showed promising results by reducing the margin of errors down to a few micrometer, which will allow the production of high-quality dental prostheses with accuracy and precision. We hope that the newly proposed alignment method can be further investigated to be applied more readily in the filed of dentistry ot provide better quality images of patients to make a more accurate diagnosis and prostheses.
