Contact Force Estimation of Continuum Robots without Embedded Sensors: A Review

open access: yesAdvanced Intelligent Systems, EarlyView.
This review surveys methods for estimating contact forces in continuum robots without embedded sensors. It explains why contact force matters, classifies force patterns, and groups existing methods into three approaches based on actuation, deformation, and environment information.

Microrobotic Catheterization of the Ophthalmic Artery for Targeted Treatment of Retinoblastoma

open access: yesAdvanced Intelligent Systems, EarlyView.
A microrobotic platform is presented that allows teleoperated and autonomous navigation of flow‐driven magnetic microcatheters, MagFlow, into the ophthalmic artery for superselective intra‐arterial infusion of chemotherapy to treat retinoblastoma. Extensive benchtop validations with patient‐derived biomimetic phantoms under optical and fluoroscopic ...

Optimisation in fluoroscopy

open access: yesBiomedical Imaging and Intervention Journal, 2007
Optimisation of radiation protection in fluoroscopy is important since the procedure could lead to relatively high absorbed doses both in patients and personnel resulting in acute radiation injury. Optimisation procedures include adjustment of the fluoroscopy equipment such as exposure factors as well as proper use of automatic brightness control and ...

Incidence and Predictors of Hypoattenuated Thickening and Device‐Related Thrombus at Three Months Postprocedural CT Assessment Following Left Atrial Appendage Occlusion With Amplatzer Devices—A Single‐Center Cohort

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Left atrial appendage occlusion (LAAO) has become a valuable alternative to long‐term anticoagulation for stroke prevention in patients with non‐valvular atrial fibrillation (AF), especially in those at high bleeding risk. Hypoattenuated thickening (HAT) and device‐related thrombus (DRT) remain notable postprocedural concerns ...
