Detailed Description

Class for performing temporal calibration.

Load a US Acquisition data set, and run calibrate(). The algorithm will extract the probe movement from the tracking data and from the us images, and use correlation to find the shift between them.

The shift sign is given from: frames = tracking + shift

double cx::TemporalCalibration::calibrate ( bool *  success)

Find temporal calibration shift (frames = tracking + shift) from the loaded data series.

  • use correlation to find shifts between volumes
    • use the first image as ref for all others
    • as a first: use global maxima to create data
  • compute the component of the shift in e_z in t space, s(t)
  • compute tracking data along e_z in t space, q(t).
  • use correlation to find shift between the two sequences.
  • the shift is the difference between frame timestamps and tracking timestamps -> temporal calibration.
  • add this as a delta to the current cal.
