class snake.core.engine.base.BaseAcquisitionEngine(*, model='simple', snr=inf)

Bases: object

Base acquisition engine.

Specific step can be overwritten in subclasses.

Methods

__init__

Attributes

log	Get a logger.
model
snr

Parameters:

• model (str)

• snr (float)

property log: Logger

Get a logger.

_acquire_ksp_job(filename, chunk, tmp_dir, shared_phantom_props=None, model='T2s', **kwargs)

Entry point for worker.

This handles the io part (Read dataset, write partial k-space), and dispatch to specialized functions for getting the k-space.

Parameters:

• filename (PathLike)

• chunk (Sequence[int])

• tmp_dir (str)

• shared_phantom_props (tuple[str, ArrayProps, ArrayProps, ArrayProps] | None)

• model (str)

• kwargs (Mapping[str, Any])

Return type:

str

__call__(filename, sampler, phantom, sim_conf, handlers=None, smaps=None, coil_cov=None, worker_chunk_size=0, n_workers=0, **kwargs)

Perform the acquisition and fill the dataset.

Parameters:

• filename (PathLike)

• sampler (BaseSampler)

• phantom (Phantom)

• sim_conf (SimConfig)

• handlers (list[AbstractHandler] | HandlerList | None)

• smaps (ndarray[Any, dtype[_ScalarType_co]] | None)

• coil_cov (ndarray[Any, dtype[_ScalarType_co]] | None)

• worker_chunk_size (int)

• n_workers (int)

• kwargs (Any)
