Double volumetric navigators for real-time simultaneous shim and motion measurement and correction in Glycogen Chemical Exchange Saturation Transfer (GlycoCEST) MRI
… biopsies are invasive and limit the frequency of measurements and the number of sites that can be assessed. Non-invasive methods for quantifying glycogen in vivo are therefore desirable in order to understand the pathophysiology of common diseases with dysregulated glycogen metabolism such as …

ASTM assessment of a novel shoulder prosthetic design: measurement of glenoid edge motion in three degrees of freedom
… also deflect horizontally and with a tilting motion. Therefore, the standardised test provides limited information regarding the glenoid behaviour. To measure the complex motions of the glenoid edges, an ASTM conforming test rig was designed and then augmented with a novel edge motion …

Mechanical design of an ultrasonic tomographic imaging system
… system is intended to augment a system for motion measurement as well as a framework for the integration of motion and US data. The design of the imaging system below represents early steps towards a full-volume imaging technique for use in computer-aided prosthetic socket design.

Simplified Analysis of IMU Sensor Corruptions on Existing Pendulation Control System For Ship-Mounted Crane
… directly correlates to the ship's pitch and roll motion that in turn relates to the current particular sea-state. In this study, we analyze an existing Pendulation Control System (PCS) developed by Sandia National Laboratories that reduces the payload's pendulation movement during transport. This …

Design and Optimization of Four-Dimensional Cone-Beam Computed to mography In Image-Guided Radiation Therapy
<p>The influence of respiratory motion on patient anatomy poses a challenge to accurate radiation therapy, especially in lung cancer treatment. Modern radiation therapy planning uses models of tumor respiratory motion to account for target motion in targeting. The tumor motion model can be verified …

The effect of ankle-foot orthosis on gait and the procedures used to assess bi-articular muscle length and spasticity in subjects with diplegic cerebral palsy
… tools used to conduct assessment procedures and measurement processes were tested in the assessment of bi-articular muscles (specifically rectus femoris), to ascertain if results were predictive of presenting gait deviations and hence provide information to optimise treatment.The results of …

Influence of motion profile on estimating anatomical elbow joint axes using inertial measurement units
Current human motion measurement systems using inertial measurement units (IMUs) typically rely on precise alignment, static calibration poses, or dynamic calibration motions. Muller et al. recently proposed a method for online calibration of the human elbow anatomical joint axes via decomposition …

Use of a Spine Robot Employing a Real Time Force Control Algorithm to Develop, Simulate, and Compare Spinal Biomechanical Testing Protocols: Eccentric Loading, Pure Moment, and a Novel Head Weight Protocol
… specimen end throughout an entire range of motion. The objective of this study was to simulate and compare the EL protocol, PM protocol, and the newly developed HWL protocol on a single programmable robotic testing frame with a consistent specimen sample group.</p> <p>Six fresh subaxial …

Global optimization methods for full-reference and no-reference motion estimation with applications to atherosclerotic plaque motion and strain imaging
Pixel-based motion estimation using optical flow models has been extensively researched during the last two decades. The driving force of this research field is the amount of applications that can be developed with the motion estimates. Image segmentation, compression, activity detection, object …

Describing motions in biological tissues: a continuum active model and improving measurements
Motions in biological tissues strongly influence their properties and are crucial for their functions. This is true starting from the scale of single molecules, all the way up to the scale of entire tissues. One of the key properties distinguishing motions in living systems from those in dead …
