Detailed Description
Projection data info for data from a scanner with discrete dtectors organised by blocks.
This class also contains some functions specific for (static) full-ring PET scanners. In this case, it is assumed that for 'raw' data (i.e. no mashing) sinogram space is 'interleaved': 2 adjacent LOR_angles are merged to 1 'view', while the corresponding bins are interleaved:
before interleaving after interleaving
a00 a01 a02 ... view 0: a00 a10 a01 a11 ...
a10 a11 ...
a20 a21 a22 ... view 1: a20 a30 a21 a31 ...
a30 a31 ...This (standard) interleaving is done because for 'odd' LOR_angles there is no LOR which goes through the origin.
- Interchanging the 2 detectors
When the ring difference = 0 (i.e. a 2D - or direct - sinogram), interchanging the 2 detectors does not change the LOR. This is why (in 2D) one gets away with a full sinogram size of num_views * 2 * num_views, where the size of 'detector-space' is twice as large. However, in 3D, interchanging the detectors, also interchanges the rings. One has 2 options:
- have 1 sinogram with twice as many views, together with the rings as 'unordered pair' (i.e. ring_difference is always >0)
- have 2 sinograms of the same size as in 2D, together with the rings as 'ordered pair' (i.e. ring_difference can be positive and negative). In STIR, we use the second convention.
