    A novel ultrasound speckle-tracking algorithm was developed for sub-pixel diaphragm deformation analysis in healthy beagles.

  • 2

    The SOCS algorithm effectively tracked diaphragm contraction and relaxation during respiratory movements without significant differences between hemidiaphragms.

  • 3

    Global diaphragm strain showed significant differences between the left and right hemidiaphragms, indicating sensitivity to imaging-plane selection.

  • 4

    The study highlights the limitations of traditional B-mode and M-mode ultrasound in providing detailed mechanical characteristics of the diaphragm.

  • 5

    This pilot study demonstrates the feasibility of using ultrasound speckle-tracking for accurate diaphragm deformation assessment.
