Module providing common Brain MRI Augmentation Methods for PyTorch.

Note

This page is a reference documentation. It only explains the class signature, and not how to use it. Please refer to the gallery for the big picture.

class brainrise.intensity.RandomSpike(n_spikes=1, intensity=(0.1, 1), seed=None)[source]¶

Add random MRI spike artifacts.

__init__(n_spikes=1, intensity=(0.1, 1), seed=None)[source]¶

Init class.

Parameters

n_spikes : int, default 1

the number of spikes presnet in k-space. Larger values generate more distorted images.

intensity : float or 2-uplet, default (0.1, 1)

Ratio between the spike intensity and the maximum of the spectrum. Larger values generate more distorted images.

seed : int, default None

seed to control random number generator.
