NAME

  XrayImaging

SYNOPSIS

  call XrayImaging (integer, intent (in) :: blockCount, 
                    integer, intent (in) :: blockList (:), 
                    real,    intent (in) :: timeStep,
                    real,    intent (in) :: timeSimulation)

DESCRIPTION

  Launches batches of detector X-rays onto the domain and records their attenuation on
  the detector screen(s). This is the driver routine for X-ray imaging at a particular
  time during the simulation. The domain structure and properties are assumed to
  remain frozen during the traversion of the X-rays.

  Currently the X-rays do not interact with the domain, hence no domain update
  is necessary.

  The code consists of the following basic steps:

         1) Create the detector X-rays
         2) Record the X-rays attenuation through the domain
         3) Record each X-ray intensity on the detector file(s)

  The code can handle a larger number of X-rays than there is memory available
  by sending batches of X-rays and reusing available memory.

ARGUMENTS

  blockCount      : Number of blocks on current processor
  blockList       : All block ID numbers
  timeStep        : The current time step duration
  timeSimulation  : current simulation time

NOTES

  The current implementation can handle more than one X-ray detector. The X-ray
  paths are straight lines through the domain.
