Detailed Description
Abstract MR acquisition data container class.
Member Function Documentation
◆ get_kspace_order()
| std::vector< KSpaceSubset::SetType > MRAcquisitionData::get_kspace_order | ( | ) | const |
Function to get the indices of the acquisitions belonging to different dimensions of k-space.
All acquisitions belong to only one subset in a multi-dimensional k-space. This function returns a vector of sets of indices belonging to the acquisitions of the individual subsets.
◆ organise_kspace()
| void MRAcquisitionData::organise_kspace | ( | ) |
Function to go through Acquisitions and assign them to their k-space dimension.
All acquisitions belong to only one subset in a multi-dimensional k-space. This function goes through all acquisitions in the container, extracts their subset (i.e. which slice contrast etc.) and stores this information s.t. consisten subsets (i.e. all acquisitions belonging to the same slice) can be extracted.
◆ read()
| void MRAcquisitionData::read | ( | const std::string & | filename_ismrmrd_with_ext | ) |
Reader for ISMRMRD::Acquisition from ISMRMRD file. filename_ismrmrd_with_ext: filename of ISMRMRD rawdata file with .h5 extension.
In case the ISMRMRD::Dataset constructor throws an std::runtime_error the reader catches it, displays the message and throws it again. To avoid reading noise samples and other calibration data, the TO_BE_IGNORED macro is employed to exclude potentially incompatible input.
