As an integral part of patient care, nursing is required to constantly adapt changes in the healthcare system, as well wider financial and societal environment. Among key factors driving these aging population. Combined with existing shortage caregiving professionals, accommodating for patients elderly needs within hospitals, elderly-care facilities at a home setting, becomes challenge. Amongst technological solutions that have evolved response developments, assistive robotics claim pivotal...
The rapid deformation of brain tissue in response to head impact can lead traumatic injury. In vivo measurements during non-injurious impacts are necessary understand the underlying mechanisms injury and compare computational models biomechanics. Using tagged magnetic resonance imaging (MRI), we obtained three-dimensional strain tensors that resulted from a mild after neck rotation or extension. Measurements maximum principal (MPS) peaked shortly impact, with maximal values 0.019–0.053...
Abstract Background User interfaces play a vital role in the planning and execution of an interventional procedure. The objective this study is to investigate effect using different user for transrectal robot‐assisted MR‐guided prostate biopsy (MRgPBx) augmented reality (AR) environment. Method End‐user studies were conducted by simulating MRgPBx system with end‐ side‐firing modes. information from operator was rendered on HoloLens as output interface. Joystick, mouse/keyboard, holographic...
Abstract The aim of this work is to develop a remotely controlled manipulator perform minimally invasive diagnostic and therapeutic interventions in the abdominal thoracic cavities, with real-time magnetic resonance imaging (MRI) guidance inside clinical cylindrical MR scanners. composed three degree freedom Cartesian motion system, which resides outside gantry scanner, serves as holder global positioner arm extends scanner. At its distal end, arm’s end-effector can carry an interventional...
This Letter proposes an end-to-end mobile tele-echography platform using a portable robot for remote cardiac ultrasonography. Performance evaluation investigates the capacity of long-term evolution (LTE) wireless networks to facilitate responsive tele-manipulation and real-time ultrasound video streaming that qualifies clinical practice. Within this context, thorough coding standards comparison applications is performed, data set ten videos. Both objective subjective (clinical) quality...
Shape-control in an architectural context is expected to provide unique opportunities for buildings with enhanced functionality, flexibility, energy performance, and occupants comfort. An concept proposed which consists of a parallel arrangement planar n-bar mechanisms formulating its skeleton structure membrane material stretched over it define the building envelope. Overall shape changes involve coordinated motion individual mechanisms. Each linkage equipped one actuator as well brakes...
Abstract Background This study presents user evaluation studies to assess the effect of information rendered by an interventional planning software on operator's ability plan transrectal magnetic resonance (MR)‐guided prostate biopsies using actuated robotic manipulators.

Background Performing minimally invasive interventions under direct MRI guidance offers significant advantages. Required accessibility to the patient inside scanner is fairly limited, and employment of robotic assistance has been proposed. The development MR-compatible systems entails engineering challenges related geometric constraints magnetic nature scanning environment. Methods A novel, general-purpose, manipulation system developed for performance a cylindrical guidance. endowed with...
Prostate biopsy is considered as a definitive way for diagnosing prostate malignancies. Urologists are currently moving towards MR-guided biopsies over conventional transrectal ultrasound-guided cancer detection. Recently, robotic systems have started to emerge an assistance tool urologists perform biopsies. However, these designed specific clinical environment and cannot be adapted modifications or changes applied the setting and/or workflow. This work presents preliminary design of...
This work presents an interventional planning software to be used in conjunction with a robotic manipulator perform transrectal MR guided prostate biopsies. The was designed taking consideration generic under the two modes of operation: side-firing and end-firing biopsy needle. Studies were conducted urologists using plan virtual results show features relevant for operating efficiently operation.
The control problem for flexible-multilink robots carrying large payloads is revisited. A set of nonlinear approximate equations describing the payload-dominated dynamics flexible plant used in conjunction with passivity property satisfied by a suitably defined modified input–output pair system, to derive globally asymptotically stable controller together its adaptive counterpart. Experimental results involving specially designed 3-degree-of-freedom planar arm two links, demonstrate their...
The development of a general-purpose robotic system at the Washington University for performing minimally invasive interventions with real-time MR guidance is reviewed. In this paper, criteria upon which was based, and an overview its components, design, prototyping manipulator, control components their general integration logic presented. human-machine interface practice MR-guided are described. It concluded that when looking into cost-effectiveness MR-compatible systems, one cannot ignore...
Networks of smart cameras, equipped with on-board processing and communication infrastructure, are increasingly being deployed in a variety different application fields, such as security surveillance, traffic monitoring, industrial critical infrastructure protection. The task(s) that network cameras executes these applications, e.g., activity monitoring object identification, can be severely degraded due to errors the detection module. However, most cases, higher level tasks decision making...
Structures enabling transformability of buildings, components and materials at different levels gain significance in view a sustainable built environment. Such structures are capable obtaining shapes response to varying functional, environmental or loading conditions. Certain limitations classic tensegrity scissor-like structures, applied so far an architectural engineering context, attributed limited number possible configurations big actuators required. In this rigid-bar linkages offer...
A popular configuration for the actuation of robotic manipulators with articulated joints is to have motors directly attached joints. This approach does not involve any transmission elements between actuators and it advantageous in many respects. However, certain cases this may be appropriate remotely-actuated desirable. In article different alternatives implementation remote would discussed a case study presented relevant arm, which was designed operate inside closed cylindrical magnetic...
