This class is a child of the vProjector class implementing the classic Siddon ray tracer.
This class implements the classic Siddon algorithm which is a ray-tracer algorithm calculating the exact length of a line through each voxel it crosses. Reference: R. L. Siddon, "Fast calculation of the exact radiological path for a three-dimensional CT array", Med. Phys., vol. 12, pp. 252-5, 1985.

The constructor of iProjectorClassicSiddon.
This is the default and unique constructor. It does not take any parameter and its role is only to affect default values to each member of the class.
Definition at line 29 of file iProjectorClassicSiddon.cc.
The destructor of iProjectorClassicSiddon.
This is the default and unique destructor. It does not take any parameter and its role is only to free or delete all structures that were built by this class.

| int iProjectorClassicSiddon::CheckSpecificParameters | ( | ) | [private, virtual] |
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.
Implements vProjector.
Definition at line 90 of file iProjectorClassicSiddon.cc.
This function is used to compute and provide an estimate of the maximum number of voxels that could contribute to a projected line.
The vProjector implementation simply returns the total image's number of voxels, but it can be overloaded by children to provide a better estimate in order to optimize and reduce memory requirements of the oProjectionLine buffers when using the FIXED_LIST_STRATEGY.
Reimplemented from vProjector.

| int iProjectorClassicSiddon::InitializeSpecific | ( | ) | [private, virtual] |
This function is used to initialize specific stuff to the child projector.
It is called by the public Initialize() function from the mother.
Implements vProjector.

| int iProjectorClassicSiddon::ProjectWithoutTOF | ( | int | a_direction, |
| oProjectionLine * | ap_ProjectionLine | ||
| ) | [private, virtual] |
A function to project without TOF.
| 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.
Implements vProjector.

| int iProjectorClassicSiddon::ProjectWithTOFBin | ( | int | a_direction, |
| oProjectionLine * | ap_ProjectionLine | ||
| ) | [private, virtual] |
A function to project with TOF binned information.
| 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.
Implements vProjector.

| int iProjectorClassicSiddon::ProjectWithTOFPos | ( | int | a_direction, |
| oProjectionLine * | ap_ProjectionLine | ||
| ) | [private, virtual] |
A function to project with TOF continuous information.
| 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.
Implements vProjector.

| int iProjectorClassicSiddon::ReadConfigurationFile | ( | const string & | a_configurationFile | ) | [virtual] |
A function used to read options from a configuration file.
| 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.
Implements vProjector.
Definition at line 51 of file iProjectorClassicSiddon.cc.
| int iProjectorClassicSiddon::ReadOptionsList | ( | const string & | a_optionsList | ) | [virtual] |
A function used to read options from a list of options.
| 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.
Implements vProjector.
Definition at line 64 of file iProjectorClassicSiddon.cc.
| void iProjectorClassicSiddon::ShowHelpSpecific | ( | ) | [private, virtual] |
A function used to show help about the child projector.
This function must describe what the module 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 the implementation of the pure virtual function inherited from the abstract class vProjector.
Implements vProjector.
