opengate.contrib.spect.genm670.add_ge_nm67_spect_head(sim, name='spect', collimator_type='lehr', debug=False)

Collimators: - False : no collimator - lehr : holes length 35 mm, diam 1.5 mm, septal thickness : 0.2 mm - megp : holes length 58 mm, diam 3 mm, septal thickness : 1.05 mm - hegp : holes length 66 mm, diam 4 mm, septal thickness : 1.8 mm

Collimator LEHR: Low Energy High Resolution (for Tc99m) Collimator MEGP: Medium Energy General Purpose (for In111, Lu177) Collimator HEGP: High Energy General Purpose (for I131)

opengate.contrib.spect.genm670.add_ge_nm670_spect_collimator(sim, name, head, collimator_type, debug)

Start with default lehr collimator description, then change some parameters for the other types
