[Castor-users] Question about the list-mode ToF algorithm

[Maxime Toussaint]

Hi,

There are two algorithms described in the CASToR Time-of-Flight PET documentation: one for binned data and one for list-mode. I had never thought that the list-mode version could be implemented with continuous TOF information. I would like to see the details behind the development of the update formula, equation (18) in the document, however the papers I have found seems to use TOF bins with list-mode data.
  
Could you refer me to an article/document that gives more details on how this formula is obtained?

Have a nice day,
Maxime Toussaint
