[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
