[Pet]

 The PET scanner generator page allows the user to create a PET
 scanner geometry, using his own configuration or from a set of
 predefined commercial scanners.

 The geometry is composed by three components:
      i. Crystals block, a unit that contains many rectangular
         crystals
     ii. Module, repetition of crystal blocks
    iii. A repetition of the crystal modules using LATTICE around the
         patient

 Axes Naming:
 ~~~~~~~~~~~~
 The geometry will be generated along the Z axis on the X-Y plane.
 The naming of the axes used are the following:

    Radial     Along the radius of the scanner. Origin is at X=Y=0

    Azimuthal  Azimuthal angle of the scanner starting from X=0

    Axial      Equal to the Z-direction


 Label Frames
 ~~~~~~~~~~~~
   Block
   -----
     NR:        Number of crystals along the radial direction
     DR:        Thickness of crystals along the radial direction
     dR:        Gap between crystals along the radial direction


     Nz:        Number of crystals along the axial/Z direction
     Dz:        Thickness of crystals along the axial/Z direction
     dz:        Gap between crystals along the axial/Z direction


     NTheta:    Number of crystals along the azimuthal (theta) direction
     DTheta:    Thickness of crystals along the azimuthal (theta) direction
     dTheta:    Gap between crystals along the azimuthal (theta) direction

   Module
   ------
     MR:        Number of blocks along the radial direction
     SR:        Gap between blocks along the radial direction

     Mz:        Number of blocks along the axial/Z direction
     Sz:        Gap between blocks along the axial/Z direction

     MTheta:    Number of blocks along the azimuthal (theta) direction
     STheta:    Gap between blocks along the azimuthal (theta) direction


   Pet
   ---
     Modules:   Number of crystal modules composing the scanner

     Radius:    Inner(minimum) radius location of the crystal
                modules

     Angle:     Opening angle for half of the PET. 180deg is
                for a full PET system

     Material:  Material to be assigned to the crystals.

                
WARNING:
the material definition is not automatically inserted to the input. The user has to inserted it from the database Region: FLUKA region name where the scanner will be placed. The region expression will be modified, all crystal modules will be subtracted from it
