Background
The current study proposes simple methods for assessing the performance of robotic devices intended for Magnetic Resonance Imaging (MRI)‐guided needle biopsy.
Methods
In‐house made agar‐based breast phantoms containing biopsy targets served as the main tool in the evaluation process of an MRI compatible positioning device comprising a needle navigator. The motion accuracy of mechanical...
Background
Herein, a robotic system offering Magnetic Resonance‐guided Focused Ultrasound (MRgFUS) therapy of thyroid nodules was developed.
Methods
The robotic system offers linear motion in 2 PC‐controlled axes that navigate a 3 MHz single‐element focused transducer. The system, through a C‐arm structure attaches to the table of Magnetic Resonance Imaging (MRI) scanners and couples to the neck...
Background
High‐quality methods for Magnetic Resonance guided Focussed Ultrasound (MRgFUS) therapy planning are needed for safe and efficient clinical practices. Herein, an algorithm for full coverage path planning based on preoperative MR images is presented.
Methods
The software functionalities of an MRgFUS robotic system were enhanced by implementing the developed algorithm. The algorithm's...
Background
A robotic system for Magnetic Resonance guided Focussed Ultrasound (MRgFUS) therapy of tumours in the breast, bone, thyroid, and abdomen was developed.
Methods
A special C‐shaped structure was designed to be attached to the table of conventional magnetic resonance imaging (MRI) systems carrying 4 computer‐controlled motion stages dedicated to positioning a 2.75 MHz spherically focussed...
Background
A prototype robotic system that uses magnetic resonance guided focused ultrasound (MRgFUS) technology is presented. It features three degrees of freedom (DOF) and is intended for thermal ablation of abdominal cancer.
Methods
The device is equipped with three identical transducers being offset between them, thus focussing at different depths in tissue. The efficacy and safety of the system...
Background
Robotic‐assisted diagnostic and therapeutic modalities require a highly accurate performance to be certified for clinical application. In this paper, three simple methods for assessing the accuracy of motion of magnetic resonance‐guided focused ultrasound (MRgFUS) robotic systems are presented.
Methods
The accuracy of motion of a 4 degrees of freedom robotic system intended for preclinical...
