Self‐Supervised Learning‐Based Framework for Speckle Reduction of Optical Coherence Tomography Images Using Frame Interpolation

Advanced Intelligent Systems, EarlyView.
In summary, a self‐supervised end‐to‐end framework for OCT image despeckling is proposed, without access to unpaired noisy–clean images or paired noisy–noisy images for training. The despeckling performance has been evaluated on 150 subjects from five retina datasets (121 subjects) and one middle ear dataset (29 subjects). Optical coherence tomography (

A Soft‐Tip Hydraulically Steerable Catheter for Enhanced Flexibility and Safety in Vascular Interventions

Advanced Intelligent Systems, EarlyView.
This study introduces a hydraulically steerable catheter with a soft tip in vascular procedures. The steering soft tip achieves a minimal diameter of 2.6 mm and supports a 180° bend. Real‐time shape and position tracking, facilitated by segmentation and endpoint detection techniques, improves navigation.

Postmortem coronary CT angiography [PDF]

Intensive Care Medicine, 2016
In the past few decades, the medical autopsy rate has markedly decreased owing to several factors such as the family’s refusal to provide consent, complexity of a time-consuming procedure, and fear of litigation in case of a missed diagnosis. On the other hand, CT and MR scans have increased the accuracy of diagnostic procedures and reduced the need ...
