mrpro.utils.slice_profiles.SliceInterpolate

class mrpro.utils.slice_profiles.SliceInterpolate(positions: Tensor, values: Tensor)

Bases: SliceProfileBase

Slice Profile based on Interpolation of Measured Profile.

__init__(positions: Tensor, values: Tensor)

Initialize the Interpolated Slice Profile.

Parameters:

• positions – Positions of the measured profile

• values – Intensities of the measured profile

forward(x: Tensor) → Tensor

Evaluate the Interpolated Slice Profile at a position.

Parameters:

x – Position at which to evaluate the profile

Return type:

Value of the profile / intensity at the given position

random_sample(size: Sequence[int]) → Tensor

Sample n random positions from the profile.

Use the profile as a probability density function to sample positions.

Parameters:

size – Number of positions to sample

Return type:

Sampled positions, shape will be size.
