Detailed Description

Class for storing and using a coincidence event from a listmode file.

The private definition is specific to the 962. Public members are generic though.

For the 962 the event word is 32 bit. To save 1 bit in size, a 2d sinogram encoding is used (as opposed to a detector number on the ring for both events). Both bin and view use 9 bits, so their maximum range is 512 values, which is fine for the 962 (which needs only 288).

The 962 has 2 other bits, one for the energy window, and a 'multiple' bit.

Todo:

use DetectionPosition etc.

get_sinogram_and_ring_coordinates()

void stir::ecat::ecat7::CListEventDataECAT962::get_sinogram_and_ring_coordinates	(	int &	view,
		int &	tangential_pos_num,
		unsigned int &	ring_a,
		unsigned int &	ring_b
	)		const

This routine returns the corresponding tangential_pos_num,view_num,ring_a and ring_b

set_sinogram_and_ring_coordinates()

void stir::ecat::ecat7::CListEventDataECAT962::set_sinogram_and_ring_coordinates	(	const int	view_num,
		const int	tangential_pos_num,
		const unsigned int	ring_a,
		const unsigned int	ring_b
	)

This routine constructs a coincidence event
