Reconstruction method for dvt with motion artifact reduction

The non-transitory computer-readable medium storing instructions which, when executed by a computerized DVT system, causes the computerized DVT system to:

• (S1) provide a sinogram acquired through an extraoral dental X-ray device during a rotation of at least 180 degrees around a patient's head and an initial projection geometry;
• (S2) perform geometry calibration through varying the projection geometry and evaluating the varied projection geometry using data consistency constraints derived from a first volume generated from the sinogram using the varied projection geometry in a first reconstruction method, wherein the first reconstruction method uses first reconstruction parameters;
• (S3) generate a final volume with a final reconstruction method using the varied projection geometry and final reconstruction parameters from the sinogram, wherein the first reconstruction parameters of the first reconstruction method and the final reconstruction parameters of the final reconstruction method differ in at least one reconstruction parameter.
