DoseActor does not work with repeated volumes.

with gt_dicom_rt_struct_to_image use gzip compression by default for the output mhd/raw binary image

gt_image_arithm does not work for 4D images

test072_1keepAll does not seem specific : if the time window value is modified, there is no difference. Maybe change the initial data with an increased activity rate to be able...

The energy spectrum of conventional Beta+ emitters is available. Provide similar energy spectra for Beta- emitters (177Lu, 90Y etc). Data can be found here : https://www.doseinfo-radar.com/RADARDecay.html

source energy spectrum

Change the way to name the energy spectrum in GenericSource - instead of "histogram", maybe "continuous_spectrum" (linear interpolation) - instead of "spectum_lines", maybe "discrete_spectrum"

np.float_ or np.double ?

in opengate/geometry/utility.py” Maybe “np.float_” should be “np.double”. Unsure if related to numpy 2.0 ?

Test for very long decay time

In G4 11.2, there is a change in the decay time threshold https://geant4-userdoc.web.cern.ch/UsersGuides/ForApplicationDeveloper/html/TrackingAndPhysics/physicsProcess.html?highlight=thresholdforverylongdecaytime#note-on-the-time-threshold-for-radioactive-decay-of-ions For Cs137 (30 year half life), it leads to no decay. User must change it with: /process/had/rdm/thresholdForVeryLongDecayTime...
