Opto-UNet: Optimized UNet for Segmentation of Varicose Veins in Optical Coherence Tomography [PDF]
, 2023 Human veins are important for carrying the blood from the body-parts to the heart. The improper functioning of the human veins may arise from several venous diseases. Varicose vein is one such disease wherein back flow of blood can occur, often resulting in increased venous pressure or restricted blood flow due to changes in the structure of vein.

Mixed Reality Communication for Medical Procedures: Teaching the Placement of a Central Venous Catheter [PDF]
2022 IEEE International Symposium on Mixed and Augmented Reality
(ISMAR), 2023 Medical procedures are an essential part of healthcare delivery, and the acquisition of procedural skills is a critical component of medical education. Unfortunately, procedural skill is not evenly distributed among medical providers. Skills may vary within departments or institutions, and across geographic regions, depending on the provider's training
