Qualitative and quantitative comparison of the baseline Average and SepConv +  + on three different modalities. The test images are from three modalities, i. e., angiography (1–2 row, redpartial splenic artery embolization image of a patient with megalosplenia), subtraction (3–4 row, partial splenic artery embolization image of another patient with megalosplenia) and fluoroscopy (5–6 row, redhepatic arteriogram image of a patient with liver tumor). The results of PSNR and SSIM by the methods of “Average” (third column) and “SepConv +  + ” (fourth column) are provided for references
