Detailed Description

template<class Derived>
class stir::CListEventCylindricalScannerWithViewTangRingRingEncoding< Derived >

Helper class for listmode events when using 2d sinograms and ring-pairs is most efficient.

This class simplifies coding of a CListEventCylindricalScannerWithDiscreteDetectors class in case the coordinates are stored in the raw data as view_num, tangential_pos_num, ring_a and ring_b.

The default implementations for get_detection_position() etc are somewhat inefficient in such case. This helper class provides faster implementations. For example usage, see ecat::ecat7::CListEventECAT966, but it's intended to be used as follows

class myEventClass : public  CListEventCylindricalScannerWithDiscreteDetectors<myEventClass>
{
  public:
    someType get_data();
  // etc
};

This implementation of this class relies on someType providing the following functions

class someType
{
void get_sinogram_and_ring_coordinates(int& view, int& tangential_pos_num, unsigned int& ring_a, unsigned int& ring_b) const;

void set_sinogram_and_ring_coordinates(
                      const int view_num, const int tangential_pos_num,
                      const int ring_a, const int ring_b);
// etc
};

Member Function Documentation

set_detection_position()

template<class Derived >

void stir::CListEventCylindricalScannerWithViewTangRingRingEncoding< Derived >::set_detection_position ( const DetectionPositionPair<> &  det_pos )

inlinevirtual

This routine constructs a (prompt) coincidence event

Implements stir::CListEventScannerWithDiscreteDetectors< ProjDataInfoCylindricalNoArcCorr >.

is_valid_template()

template<class Derived >

bool stir::CListEventCylindricalScannerWithViewTangRingRingEncoding< Derived >::is_valid_template ( const ProjDataInfo &  proj_data_info ) const

inlinevirtual

This method checks if the template is valid for LmToProjData.

Used before the actual processing of the data (see issue #61), before calling get_bin() Most scanners have listmode data that correspond to non arc-corrected data and this check avoids a crash when an unsupported template is used as input.

Implements stir::ListEvent.
