Detailed Description

Reads .dat files that containg scaling information about variable flip angle acquisitions.

Authors: Jason C. Crane Peder E.Z. Larson Beck(Marram) P. Olson

Example V1 format: dat_type: variable_flip_angle dat_version: 1 dat_content_name: brain_2d_17-Feb-2016 num_time_pts: 20 profile_bandwidth: 543.478261 profile_num_pts: 256 time_point: 1 signal_scaling: space_separated_float_values(256) mz_scaling: space_separated_float_values(256) time_point: 2 signal_scaling: space_separated_float_values(256) mz_scaling: space_separated_float_values(256) ... time_point: 20 signal_scaling: space_separated_float_values(256) mz_scaling: space_separated_float_values(256)

Thsigna_scaling arrays are array of scaling factors for each dynamic time point. The scaling factors are to be applied to the reconstructed data in frequency domain by dividing the complex intensities by the scaling factor at the corresponding frequency point. The bandwidth is defined (GetProfileBandwidth) with 0 hz at the center point ( GetNumTimePoints()/2 , e.g. 128 for 256 point profile.

The time index starts at 1 returns status 0 on success

Member Function Documentation

int CanReadFile ( const char *  fname )

virtual

Check to see if the extension indicates a UCSF IDF file. If so, try to open the file for reading. If that works, then return a success code. Return Values: 1 if can read the file, 0 otherwise.

References svkVariableFlipDatReader::InitDatReader(), and svkImageReader2::VARIABLE_FLIP_DAT.

void ExecuteInformation ( )

protectedvirtual

Side effect of Update() method. Used to initialize the svkDcmHeader member of the target svkImageData object and uses the header to set up the Output Informatin. Called before ExecuteData()
