PXMOD Implementation

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.

Map Parameters

PXMOD Fourier Model Parameters

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.

We would like to thank Prof. Ludwig G. Strauss (l.strauss@dkfz-heidelberg.de) for the implementation of the DFT.
