SDRD-Net: A Symmetric Dual-branch Residual Dense Network for OCT and US Image Fusion.

Ultrasound (US) images have the advantages of no radiation, high penetration, and real-time imaging, and optical coherence tomography (OCT) has the advantage of high resolution. The purpose of fusing endometrial images from optical coherence tomography (OCT) and ultrasound (US) is to combine the advantages of different modalities to ultimately obtain more complete information on endometrial thickness. To better integrate multimodal images, we first proposed a Symmetric Dual-branch Residual Dense (SDRD-Net) network for OCT and US endometrial image fusion.
