We consider x-ray acquisition from sources located on a smooth curve $\\Gamma$ in $\\mathbb{R}^3$ verifying classical Tuy's condition. In this situation, the {\\it non-trucated} cone-beam transform $D f$ of smooth densities $f$ admits an explicit inverse $Z$; however $Z$ cannot directly reconstruct $f$ from ROI-truncated projections.
