Did you know that ?
the 3DView app on Medis Suite CT can be used as a reformatter to obtain suitable multi-phase multi-slice series for LV & RV Functional analysis.
Contours traced during the LV function analysis can be loaded into the QStrain app for subsequent strain analysis based on features tracking CT.
