The Fourier Analysis model performs a Discrete Fourier Transform (DFT) in each pixel and returns the amplitude and phase of two harmonics as parametric images.
Acquisition and Data Requirements
Image Data |
Any dynamic volume data. Note that the acquisition time information is relevant for the results. |
Model Preprocessing
Add. Harmonic |
Index defining which harmonic to return in amp+ and pha+. |
thresh |
If the amplitude of the first harmonic is below the specified value of thresh, all parameters values are set to 0. |
Model Configuration
amp1 |
Amplitude of first harmonic in the Fourier analysis. |
pha1 |
Phase in [deg] of first harmonic in the Fourier analysis. |
amp+ |
Amplitude of an additional harmonic in the Fourier analysis. |
pha+ |
Phase in [deg] of the additional harmonic in the Fourier analysis. |
