Build eroded ROI in CT

According to possible gap between CT and all PETs, the spheres' mask is computed and displayed like the following :

Parameters

run_parallele: Boolean ( input )

display_fusion_roi_pet: Choice ( input )

CT: Phantom CT ( input )

Pets_mean: ListOf( Phantom PET Mean ) ( input )

PET_mean_toDisplay: Phantom PET Mean ( optional, input )

jzkSpec: Phantom Spec ( input )

step: Float ( input )

step of research : it's a radiant used by the Hough algorithm to find sphere center. For a little step, you have a more precise research, but it's more time consuming

decalage_X: Float ( optional, input )

shift on X axis . It's a number of voxels used to fix the gap between PET and CT

decalage_Y: Float ( optional, input )

shift on Y axis . It's a number of voxels used to fix the gap between PET and CT

decalage_Z: Float ( optional, input )

shift on Z axis . It's a number of voxels used to fix the gap between PET and CT

erosionMax: Integer ( optional, input )

if the sphere diameter - erosionMax > maxErosionMinSphSize, then the sphere is eroded by erosionMax else it's eroded with erosionMin

erosionMin: Integer ( input )

if the sphere diameter - erosionMax > maxErosionMinSphSize, then the sphere is eroded by erosionMax else it's eroded with erosionMin

maxErrosionMinSphSize: Integer ( input )

if the sphere diameter - erosionMax > maxErosionMinSphSize, then the sphere is eroded by erosionMax else it's eroded with erosionMin

sph_rois: Phantom ROI Sph ( output )

rotAngle_forNoise: Integer ( input )

sph_inverseSort_forNoise: Boolean ( input )

spheres' ROI are build in sphere activity, but also in noise (background). This ROI are just shifted thanks to a rotation around Z axis. If sph_inverseSor_forNoise is True, then the sphere order is reversed, so the littlest ROI in noise is near the biggest ROI in activity. Usefull to be sure to not have a noise ROI touching activity due to partial volume effect.

sph_roi_in_Noise: Phantom ROI Sph inNoise ( output )

verbose: Boolean ( input )
