Needle localization using gabor filtering in 2D ultrasound images
(IEEE, 2014)
In the percutaneous needle procedures using ultrasound (US) imaging, the needle should be detected precisely to avoid damage to the tissue and to get the samples from the appropriate site. Excessive artifacts and low ...
A personal navigation system using mems-based high-density ground reaction sensor array and inertial measurement unit
(IEEE, 2015)
This paper describes a prototype personal navigation system developed for position tracking under GPS denied environments by employing a commercial inertial measurement unit (IMU) and a MEMS-based ground reaction sensor ...
Gabor filter based localization of needles in ultrasound guided robotic interventions
(IEEE, 2014)
This paper presents an entropy based parameter tuning method for needle segmentation, and a probability map based needle tip estimation method using Gabor-based line filter. The proposed automatic parameter tuning method ...
Design and modeling of a parallel robot for ultrasound guided percutaneous needle interventions
(IEEE, 2015)
Necessity of precise positioning in percutaneous needle operations enables robotic systems to take part in medical procedures. Researches that have been done until today showed robotic systems increase the accuracy of ...
Development of an antagonistically actuated smart joint
(Trans Tech Publications, 2017)
Shape memory alloys with their phase transformation properties; have been broadly implemented in smart structures. In this study, a functional design is presented where two wires actuate antagonistically to achieve motion ...
Discrete-time integral sliding mode control of a smart joint for minimally invasive surgeries
(IEEE, 2016)
In this work, a shape memory alloy(SMA) actuator based joint (smart joint) is controlled using a discrete-time integral sliding mode (DISM) control to guide the motion of an active catheter. Controller is designed on the ...
Design and kinematics of a 5-DOF parallel robot for beating heart surgery
(IEEE, 2019)
In this paper, mechanical and electronics design of a lightweight 5-DOF robot, Ozyegin Surgery Robot I (OSI), and it's performance of tracking the heart motion for coronary artery bypass procedure (CABG) are presented. The ...
Improving the safety of medical robotic systems
(IEEE, 2018-10-09)
The significance of the robots in the medical field have been increasing rapidly. Humans and robots working together increases the strengths and decreases the limitations of surgical operations. Human life makes safety the ...
Visual tracking of multiple moving targets in 2D ultrasound guided robotic percutaneous interventions
(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 ...
Visual tracking of biopsy needles in 2D ultrasound images
(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 ...
