Enhanced Embolic Signal Analysis through Ensemble Deep Learning Techniques Utilizing Transfer Learning and Layer Freezing Strategies

open access: yesAdvanced Intelligent Systems, EarlyView.
A 10‐convolutional neural network ensemble using transfer learning and layer freezing analyzes 400 Doppler‐ultrasound spectrograms to distinguish speckle, artifact, and ESs. Soft and hard voting drive performance to 96.7% accuracy and 96.5% F1, highlighting a practical route for early embolus detection and stroke‐risk mitigation.

Carotid Artery Intervention

open access: yes, 2007
Atherosclerotic carotid artery disease is a major contributor to the incidence of stroke, particularly in the elderly. Atherosclerosis is a systemic illness and patients often present with multisystem involvement of several vascular beds including coronary, cerebral, and peripheral vascular territories. The majority of strokes related to carotid artery

Collaborative Multirobot Navigation‐Assisted Magnetic Catheter Guidance and Shape Perception with Vascular Ultrasound and Electromagnetic Tracking

open access: yesAdvanced Intelligent Systems, EarlyView.
The article develops a collaborative multirobot navigation system‐assisted magnetic catheter guidance and shape perception method using the information fusion of robotic vascular ultrasound imaging and electromagnetic tracking to reconstruct the 3D catheter's shape and vasculature. Results verify the effectiveness of the system and the potential of the

Microendovascular Neural Recording from Cortical and Deep Vessels with High Precision and Minimal Invasiveness

open access: yesAdvanced Intelligent Systems, EarlyView.
Intravascular electroencephalography (ivEEG) using micro‐intravascular electrodes was developed. Cortical‐vein ivEEG showed a higher signal‐to‐noise ratio and finer spatial resolution of somatosensory evoked potentials (SEPs) than superior sagittal sinus ivEEG, and deep‐vein ivEEG captured clear visual evoked potentials.

Carotid Artery Sonography Findings in 291 Patients Undergoing Cabg

open access: yesMajallah-i Dānishgāh-i ’Ulūm-i Pizishkī-i Shahīd Ṣadūqī Yazd, 2006
Introduction: Doppler ultrasonography (DUS) is the most preferable method for screening of carotid artery disease in patients undergoing CABG. The purpose of this study was to investigate the frequency of carotid artery disease and determine the relation
