Weakly-supervised learning for catheter segmentation in 3D frustum ultrasound.

Computerized medical imaging and graphics : the official journal of the Computerized Medical Imaging Society
Accurate and efficient catheter segmentation in 3D ultrasound (US) is essential for ultrasound-guided cardiac interventions. State-of-the-art segmentation algorithms, based on convolutional neural networks (CNNs), suffer from high computational cost ...

Screening of factors influencing catheter rotation of a vascular interventional surgical robot using design of experiment approach.

Medical engineering & physics
Over the past decades, Vascular Interventional Surgery Robots (VISR) have been developed to address the risks associated with X-rays used in minimally invasive vascular surgery procedures. Manipulation of over-the-wire catheters is necessary to perfo...

A technical guide to robotic catheter angiography with the Corindus CorPath GRX system.

Journal of neurointerventional surgery
Robotic catheter angiography is an emerging technology with the opportunity to increase procedural precision and decrease occupational hazards.1-5 In this video, we present our initial experiences with the CorPath GRX Robotic System (Corindus, a Seim...

Human colorectal cancer tissue assessment using optical coherence tomography catheter and deep learning.

Journal of biophotonics
Optical coherence tomography (OCT) can differentiate normal colonic mucosa from neoplasia, potentially offering a new mechanism of endoscopic tissue assessment and biopsy targeting, with a high optical resolution and an imaging depth of ~1 mm. Recent...

[Research on real-time detection system of catheter delivering force in vascular interventional robots].

Sheng wu yi xue gong cheng xue za zhi = Journal of biomedical engineering = Shengwu yixue gongchengxue zazhi
In existing vascular interventional surgical robots, it is difficult to accurately detect the delivery force of the catheter/guidewire at the slave side. Aiming to solve this problem, a real-time force detection system was designed for vascular inter...

Automated catheter tip repositioning for intra-cardiac echocardiography.

International journal of computer assisted radiology and surgery
PURPOSE: Intra-Cardiac Echocardiography (ICE) is a powerful imaging modality for guiding cardiac electrophysiology and structural heart interventions. ICE provides real-time observation of anatomy and devices, while enabling direct monitoring of pote...

Automatic vein measurement by ultrasonography to prevent peripheral intravenous catheter failure for clinical practice using artificial intelligence: development and evaluation study of an automatic detection method based on deep learning.

BMJ open
OBJECTIVES: Complications due to peripheral intravenous catheters (PIVC) can be assessed using ultrasound imaging; however, it is not routinely conducted due to the need for training in image reading techniques. This study aimed to develop and valida...

Development and validation of a predictive model for peripherally inserted central catheter-related thrombosis in breast cancer patients based on artificial neural network: A prospective cohort study.

International journal of nursing studies
BACKGROUND: Peripherally inserted central catheters have been extensively applied in clinical practices. However, they are associated with an increased risk of thrombosis. To improve patient care, it is critical to timely identify patients at risk of...

A survey of catheter tracking concepts and methodologies.

Medical image analysis
Catheter tracking has become an integral part of interventional radiology. Over the last decades, researchers have significantly contributed to theoretical and technical catheter tracking solutions. However, most of the published work thus far focuse...

A learning-based, region of interest-tracking algorithm for catheter detection in echocardiography.

Computerized medical imaging and graphics : the official journal of the Computerized Medical Imaging Society
Echocardiography (echo) is gaining popularity to guide the catheter during surgical procedures. However, it is difficult to discern the catheter tip in echo even with an acoustically active catheter. An acoustically active catheter is detected for th...
