Özyeğin biopsy robot: system integration architecture and motion compensation of a moving target
Ahmad, Awais; Bebek, Özkan (TÜBİTAK, 2018-05-30)This paper presents the complete system architecture of a robotic biopsy system for real-time operations. The system has individual functional blocks working simultaneously including a 5 DoF parallel robot, ultrasound (US) ... -
Real-time needle tip localization in 2D ultrasound images for robotic biopsies
Kaya, Mert; Şenel, Enes; Ahmad, Awais; Orhan, Orçun; Bebek, Özkan (IEEE, 2015)In this paper, real-time needle tip tracking method using 2D ultrasound (US) images for robotic biopsies is presented. In this method, the needle tip is estimated with the Gabor filter based image processing algorithm, and ... -
Visual tracking of biopsy needles in 2D ultrasound images
Kaya, Mert; Şenel, Enes; Ahmad, Awais; Bebek, Özkan (2016)Ultrasound (US) is one the most commonly used medical imaging techniques in percutaneous needle procedures. However, US images are inherently noisy and contain excessive number of artifacts. Hence, it is not easy to track ... -
Visual tracking of multiple moving targets in 2D ultrasound guided robotic percutaneous interventions
Kaya, Mert; Şenel, Enes; Ahmad, Awais; Bebek, Özkan (IEEE, 2017)Percutaneous needle procedures are mostly carried out with the guidance of 2D ultrasound (US) imaging. US images are inherently noisy and their resolutions are low. Hence, target tracking can be challenging. Image based ...
