Comparison of MRI-Compatible Mechatronic Systems With Hydrodynamic and Pneumatic Actuation
Publication Year: 2008, Page(s):268 - 277
Cited by: Papers (49)The strong magnetic fields and limited space make it challenging to design the actuation for mechatronic systems intended to work in MRI environments. Hydraulic and pneumatic actuators can be made MRI-compatible and are promising solutions to drive robotic devices inside MRI environments. In this paper, two comparable haptic interface devices, one with hydrodynamic and another with pneumatic actua... View full abstract»

Evaluation of Electrorheological Fluid Dampers for Applications at 3-T MRI Environment
Publication Year: 2008, Page(s):286 - 294
Cited by: Papers (23)This paper evaluates the use of electrorheological fluids (ERFs) within a magnetic resonance imaging (MRI) environment. ERF is a semiactive variable impedance material, which could be used as an alternative type of resistive force/torque generation or in combination with other actuators as a damper/clutch to modulate the output force/torque of the actuator. In this paper, an ERF damper/brake is in... View full abstract»

A 3-DOF MR-Compatible Device for Magic Angle Related
Publication Year: 2008, Page(s):316 - 324In Vivo Experiments
Cited by: Papers (17)The "magic angle" effect consists of the increase in signal intensity observed at a tendon or cartilage in a magnetic resonance image, when the tissue is oriented at an angle of approximately 55deg with respect to the main magnetic field B0. The exploitation of this phenomenon is often used to assist diagnosis of tendinous and other diseases, although practical difficulties derived from... View full abstract»

Active Vibration Control of Gradient Coils to Reduce Acoustic Noise of MRI Systems
Publication Year: 2008, Page(s):325 - 334
Cited by: Papers (11)Lorentz-force-induced vibrations in MRI systems cause significant acoustic noise levels during scanning, the main acoustic noise source being the vibrating gradient coil. In this paper, a novel active vibration control technique is presented to reduce vibrations of the gradient coil, and hence, achieve a reduction of acoustic noise during scanning. The active vibration control technique uses seism... View full abstract»

Sensing Glove for Brain Studies: Design and Assessment of Its Compatibility for fMRI With a Robust Test
Publication Year: 2008, Page(s):345 - 354
Cited by: Papers (27)In this paper, we describe a biomimetic-fabric-based sensing glove that can be used to monitor hand posture and gesture. Our device is made of a distributed sensor network of piezoresistive conductive elastomers integrated into an elastic fabric. This solution does not affect natural movement and hand gestures, and can be worn for a long time with no discomfort. The glove could be fruitfully emplo... View full abstract»

Human–Machine Interface for Robotic Surgery and Stereotaxy
Publication Year: 2008, Page(s):355 - 361
Cited by: Papers (32)While considerable technology has been integrated into the operating room, until recently, the actual performance of surgery has seen relatively few changes, relying mainly on hand-eye coordination. This paper outlines the development and composition as well as the requirements and reasoning that lead to the human-machine interface on neuroArm, a telerobotic surgical system.

The Interconnection of MRI Scanner and MR-Compatible Robotic Device: Synergistic Graphical User Interface to Form a Mechatronic System
Publication Year: 2008, Page(s):362 - 369
Cited by: Papers (5)MRI scanner and magnetic resonance (MR)-compatible robotic devices are mechatronic systems. Without an interconnecting component, these two devices cannot be operated synergetically for medical interventions. In this paper, the design and properties of a graphical user interface (GUI) that accomplishes the task is presented. The GUI interconnects the two devices to obtain a larger mechatronic syst...

Population-Based Uncalibrated Visual Servoing
Publication Year: 2008, Page(s):393 - 397
Cited by: Papers (17)This paper introduces the implementation of a recently introduced method suitable for visual servoing. The method is based on the generalization of secant methods for nonlinear optimization. The difference with existing approaches related to visual servoing is that we do not impose a linear model to interpolate the goal function. Instead, we prefer to identify the linear model by building the seca... View full abstract»
