Continuous -time Fourier Transform

1.2K
The Fourier series is instrumental in representing periodic functions, offering a powerful method to decompose such functions into a sum of sinusoids. This technique, however, necessitates modification when applied to nonperiodic functions. Consider a pulse-train waveform consisting of a series of rectangular pulses. When these pulses have a finite period, they can be accurately represented by a Fourier series. Yet, as the period approaches infinity, resulting in a single, isolated pulse, the...

  • To develop and validate an improved fiber tracking algorithm addressing the cross-track problem.
  • To enhance the accuracy and completeness of white matter tract reconstruction.
  • To differentiate nerve fiber directions in healthy controls versus patients with axonal injury and demyelinating diseases.

Main Methods:

  • Implementation of a novel fiber tracking algorithm based on continuous tracking and a two-tensor model.
  • Utilizing different models and tracking decisions based on voxel estimation types.
  • Inclusion of eight healthy subjects, two axonal injury patients, and seven demyelinating disease patients.

Main Results:

  • The improved algorithm successfully distinguished nerve fiber direction differences between healthy subjects and patients with axonal injury or demyelinating disease.
  • The novel method tracked a greater number and longer nerve fibers compared to standard continuous tracking.
  • The algorithm effectively solved the fiber crossing problem, improving tractography accuracy.

Conclusions:

  • The developed fiber tracking algorithm offers enhanced performance in reconstructing white matter tracts.
