CD16: a MATLAB-based application for estimating radiation doses from x-ray guided cardiac catheterizations in children [PDF]

open access: yesarXiv, 2018
CD16 is a MATLAB-based dosimetry system designed for rapid estimation of organ doses for x-ray guided cardiac catheterization procedures. CD16 is principally designed for epidemiological studies in which dose estimates are required for thousands of cohort members, often based on limited exposure information. The minimum data required for dose estimates

CATHETERIZATION OF THE EUSTACHIAN TUBE. [PDF]

open access: yesJournal of the American Medical Association, 1887
Dear Sir : —InThe Journalof October 15 there was published a letter from Dr. Enfield concerning the faucial method of introducing the Eustachian catheter. The doctor cauterized the Eustachian tube per fauces because the nasal septum was so deflected as to render the introduction of the catheter through the inferior meatus impracticable.

Contour and Centreline Tracking of Vessels from Angiograms using the Classical Image Processing Techniques [PDF]

open access: yesBuletinul Institutului Politehnic din Iasi, Sectia Automatica si Calculatoare, Vol. 62(66), No. 3, pp. 49-60, July 2016, ISSN 1220-2169, 2017
This article deals with the problem of vessel edge and centerline detection using classical image processing techniques due to their simpleness and easiness to be implemented. The method is divided into four steps: the vessel enhancement which implies a non-linear filtering proposed by Frangi, the thresholding using Otsu method and the contour ...

Improving Catheter Segmentation & Localization in 3D Cardiac Ultrasound Using Direction-Fused FCN [PDF]

open access: yesarXiv, 2019
Fast and accurate catheter detection in cardiac catheterization using harmless 3D ultrasound (US) can improve the efficiency and outcome of the intervention. However, the low image quality of US requires extra training for sonographers to localize the catheter.

Weakly-Supervised Learning via Multi-Lateral Decoder Branching for Tool Segmentation in Robot-Assisted Cardiovascular Catheterization [PDF]

open access: yesarXiv
Robot-assisted catheterization has garnered a good attention for its potentials in treating cardiovascular diseases. However, advancing surgeon-robot collaboration still requires further research, particularly on task-specific automation. For instance, automated tool segmentation can assist surgeons in visualizing and tracking of endovascular tools ...

Autonomous Catheterization with Open-source Simulator and Expert Trajectory [PDF]

open access: yesarXiv
Endovascular robots have been actively developed in both academia and industry. However, progress toward autonomous catheterization is often hampered by the widespread use of closed-source simulators and physical phantoms. Additionally, the acquisition of large-scale datasets for training machine learning algorithms with endovascular robots is usually ...
