Functions to get parameters @{
Function to shift the time data This is useful if the start time of the scan and the start time of the plasma are not precisely correct. This can be measured by the plasma peak and the very first frames of the dynamic images. Note This cannot be estimated in the current implementation of the direct reconstructions. Thus, it is given externally.

Member Function Documentation

read_plasma_data()

void stir::PlasmaData::read_plasma_data ( const std::string  input_string )

inline

Implementation to read the input function from ONLY a 3-columns data file (Time-InputFunctionRadioactivity-WholeBloodRadioactivity).

Todo:

Implementation to set the input units.

Implementation to read the input function from ONLY a 3-columns data file (Time-InputFunctionRadioactivity-TotalBloodRadioactivity).

Warning

Assumes that the input function is not corrected for decay.

get_sample_data_in_frames()

PlasmaData stir::PlasmaData::get_sample_data_in_frames ( TimeFrameDefinitions  time_frame_def )

inline

Sorts the plasma_data into frames.

Sorts the plasma_data into frames

Warning

It corrects for decay if the data are not decay corrected.

Returns

PlasmaData are in start-end frames time mode.

set_time_frame_definitions()

void stir::PlasmaData::set_time_frame_definitions ( const TimeFrameDefinitions &  plasma_fdef )

inline

Note

The set_time_frame_definitions() is prefered than giving directly the Scan TimeFrameDefinitions since the sample may not be measured for all the frames
For example at the beginning or at the end of the scan.
