In this work, we develop an innovative deep learning framework of Lateral and Axial Resolution Restoration (LARR) to break the contradiction between imaging resolution and speed. LARR employs a self-supervised training scheme to computationally restore the sparsely sampled TPF images to resolution isotropic images by 4-fold axial and 16-fold lateral resolution enhancement. The simulation studies and experimental results demonstrate the excellent performance of LARR to preserve fine structural features with improved signal-to-noise ratio and structure similarity index. Moreover, the TPF imaging system with the LARR is able to achieve 60-fold improved imaging speed and comparable resolution as compared with the conventional TPF system. The outstanding performance makes LARR a potential tool for fast TPF imaging with high resolution.</p>\u0000 </div>","PeriodicalId":184,"journal":{"name":"Journal of Biophotonics","volume":"18 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143257661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we proposed a registration method for endoscopic OCTA imaging in a proximally controlled OCT System. Global registration and A-line registration were employed to correct the distortion caused by mechanical friction between the catheter sheath and torque coil.
