Feasibility study of dose calculation based on contrast-enhanced computed tomography for stereotactic body radiation therapy of lung metastases treated with MR-Linac
The reliability of contrast-enhanced CT (CHCT) as a reference image for MR-based dose calculation in lung stereotactic body radiation therapy (SBRT) with MR-Linac remains uncertain due to contrast-induced electron density (ED) discrepancy. Whether CHCT can be used as a reference image for dose calculation for pat...
