Member Function Documentation

int iProjectorIncrementalSiddonMulti::CheckSpecificParameters ( )

privatevirtual

A private function used to check the parameters settings specific to the child projector.

This function is used to check that all parameters specific to the projector are correctly set within allowed values. It is called by the CheckParameters() function of the mother class. It is the implementation of the pure virtual function inherited from the abstract mother class vProjector.

Returns: An integer reflecting the check status; 0 if no problem, another value otherwise.

Implements vProjector.

Definition at line 99 of file iProjectorIncrementalSiddonMulti.cc.

INTNB iProjectorIncrementalSiddonMulti::EstimateMaxNumberOfVoxelsPerLine ( )

virtual

This function is used to compute and provide an estimate of the maximum number of voxels that could contribute to a projected line.

This function is an overloaded implementation of the virtual mother function. It is used to compute and provide an estimate of the maximum number of voxels that could contribute to a projected line.

Returns: The estimate of the maximum number of voxels contributing to a line.

Reimplemented from vProjector.

Here is the call graph for this function:

int iProjectorIncrementalSiddonMulti::InitializeSpecific ( )

privatevirtual

This function is used to initialize specific stuff to the child projector.

It is called by the public Initialize() function from the mother.

Returns: An integer reflecting the initialization status; 0 if no problem, another value otherwise.

Implements vProjector.

Definition at line 116 of file iProjectorIncrementalSiddonMulti.cc.

int iProjectorIncrementalSiddonMulti::ProjectWithoutTOF	(	int	a_direction,
		oProjectionLine *	ap_ProjectionLine
	)

privatevirtual

A function to project without TOF.

Parameters

int	a_direction
oProjectionLine*	ap_ProjectionLine

Projects the provided line following the provided direction, without TOF. It fills the provided oProjectionLine. It is an implementation of the pure virtual function from the mother class.

Returns: An integer reflecting the projection status; 0 if no problem, another value otherwise.

Implements vProjector.

int iProjectorIncrementalSiddonMulti::ProjectWithTOFBin	(	int	a_direction,
		oProjectionLine *	ap_ProjectionLine
	)

privatevirtual

A function to project with TOF binned information.

Parameters

int	a_direction
oProjectionLine*	ap_ProjectionLine

Projects the provided line following the provided direction, with TOF information describe as a histogram bin. It fills the provided oProjectionLine. It is an implementation of the pure virtual function from the mother class.

Returns: An integer reflecting the projection status; 0 if no problem, another value otherwise.

Implements vProjector.

int iProjectorIncrementalSiddonMulti::ProjectWithTOFPos	(	int	a_direction,
		oProjectionLine *	ap_ProjectionLine
	)

privatevirtual

A function to project with TOF continuous information.

Parameters

int	a_direction
oProjectionLine*	ap_ProjectionLine

Projects the provided line following the provided direction, with TOF described as a continuous measurement. It fills the provided oProjectionLine. It is an implementation of the pure virtual function from the mother class.

Returns: An integer reflecting the projection status; 0 if no problem, another value otherwise.

Implements vProjector.

Definition at line 424 of file iProjectorIncrementalSiddonMulti.cc.

int iProjectorIncrementalSiddonMulti::ReadConfigurationFile ( const string & a_configurationFile )

virtual

A function used to read options from a configuration file.

Parameters

const string& a_configurationFile

This function implements the reading of all options associated to the child projector, from a configuration file. It is the implementation of the pure virtual function inherited from the abstract class vProjector. It checks the reading status but not the options values that will be checked by the CheckSpecificParameters() function.

Returns: An integer reflecting the reading success; 0 if success, another value otherwise.

Implements vProjector.

Definition at line 50 of file iProjectorIncrementalSiddonMulti.cc.

Here is the call graph for this function:

int iProjectorIncrementalSiddonMulti::ReadOptionsList ( const string & a_optionsList )

virtual

A function used to read options from a list of options.

Parameters

const string& a_configurationFile

This function implements the reading of all options associated to the child projector, from a list of options. It is the implementation of the pure virtual function inherited from the abstract class vProjector. It checks the reading status but not the options values that will be checked by the CheckSpecificParameters() function.

Returns: An integer reflecting the reading success; 0 if success, another value otherwise.

Implements vProjector.

Definition at line 68 of file iProjectorIncrementalSiddonMulti.cc.

Here is the call graph for this function:

void iProjectorIncrementalSiddonMulti::ShowHelpSpecific ( )

privatevirtual

A function used to show help about the child module.

This function must describe what the projector does and how to use it. It describes in details the different parameters of the projector, and how to set them through the use of a configuration file or a list of options. It is pure virtual so is implemented by children. It is private because called by the public ShowHelp() function.

Implements vProjector.
