Detailed Description

Class providing map functionality to convert detector indices to spatial coordinates. Map files can have 5 or 6 tab- or comma-separated columns. Lines beginning with '#' are ignored. The layer column is optional

Format: ring,detector,(layer,)x,y,z An empty line will terminate the reading at that line.

Optionally LOR end-points can be randomly displaced using a Gaussian distribution with standard deviation sigma (in mm).

void stir::DetectorCoordinateMap::set_detector_map

(

const det_pos_to_coord_type &

coord_map

)

stores the map

applies sorting to standard STIR order

find_detection_position_given_cartesian_coordinate()

Succeeded stir::DetectorCoordinateMap::find_detection_position_given_cartesian_coordinate	(	DetectionPosition<> &	det_pos,
		const CartesianCoordinate3D< float > &	cart_coord ) const

first round the cartesian coordinates, it might happen that the cart_coord is not precisely pointing to the center of the crystal and then the det_pos cannot be found using the map
