Motion field of B-Spline algorithm,

[Hussam Jassim]

Dear developer,

Good morning,

I  run registration process using Plastimatch, and successfully registered the two CT scans images using B-Spline algorithm and get deformable vector field (DVF) matrix.

Actually, I am working on manipulating the DVF, but it is not clear to me in which direction Plastimatch calculates DVF., for instance vector in anterior-posterior (AP) direction, left-right (LR) direction or superior-inferior direction.

Thank you in advance

Hi, Sorry for the delay.

The DVF is three dimensional, and includes all three directions.
