mitk.ArbitraryTimeGeometry

class mitk.ArbitraryTimeGeometry

Bases: TimeGeometry

TimeGeometry with user-defined time points per step.

Use when the time points are not evenly spaced (gated acquisitions, re-binned reconstructions, sparse 4D series).

Parameters:

time_step – Time-step index.

Returns:

A 2-tuple of floats.

is_valid_time_point(self: mitk.TimeGeometry, time_point: SupportsFloat) → bool

Return True if the time point is within the geometry’s bounds.

Parameters:

time_point – Candidate time point.

is_valid_time_step(self: mitk.TimeGeometry, time_step: SupportsInt) → bool
