Ha, Xuan Thao (author), Wu, D. (author), Ourak, Mouloud (author), Borghesan, Gianni (author), Dankelman, J. (author), Menciassi, Arianna (author), Poorten, Emmanuel Vander (author)In this article, a deep learning method for the shape sensing of continuum robots based on multicore fiber bragg grating (FBG) fiber is introduced. The proposed method, based on an artificial neural network (ANN), differs from traditional approaches, where accurate shape reconstruction requires a tedious characterization of many...journal article 2023

Ha, Xuan Thao (author), Wu, D. (author), Lai, C. (author), Ourak, Mouloud (author), Borghesan, Gianni (author), Menciassi, Arianna (author), Vander Poorten, Emmanuel (author)Continuum robots such as robotic catheters are increasingly being used in minimally invasive surgery. Compliance contributes to enhanced safety during e.g. catheter insertion, however, estimation of contact force and location may help clinicians avoiding exerting excessive force. Ultimately this could lead to faster and safer interventions....journal article 2022

(author), Menciassi, Arianna (author), Poorten, Emmanuel Vander (author)In cardiovascular interventions, when steering catheters and especially robotic catheters, great care should be paid to prevent applying too large forces on the vessel walls as this could dislodge calcifications, induce scars or even cause perforation. To address this challenge, this paper presents a novel compliant motion control algorithm...journal article 2022

Wu, Di (author), Zhang, Yao (author), Ourak, Mouloud (author), Niu, Kenan (author), Dankelman, J. (author), Vander Poorten, Emmanuel B. (author)Catheters are increasingly being used to tackle problems in the cardiovascular system. However, positioning precision of the catheter tip is negatively affected by hysteresis. To ensure tissue damage due to imprecise positioning is avoided, hysteresis is to be understood and compensated for. This work investigates the feasibility to model...journal article 2021
