Detailed Description

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.

Member Function Documentation

◆ CheckSpecificParameters() [1/2]

int iProjectorClassicSiddon::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 90 of file code/src/projector/iProjectorClassicSiddon.cc.

◆ CheckSpecificParameters() [2/2]

int iProjectorClassicSiddon::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. It is pure virtual so is implemented by children.

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

Implements vProjector.

◆ EstimateMaxNumberOfVoxelsPerLine() [1/2]

INTNB iProjectorClassicSiddon::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.

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.

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

Reimplemented from vProjector.
