Conventional magnetic resonance imaging (MRI) scanners are bulky and heavy. It limits their applications at places, for example, in an ambulance or a combat field hospital. The disadvantages of conventional MRI system have led to increasing interests the development portable one. One challenges scanner is build homogenous static within volume size human parts, head, imaging. In this paper, we presented design modified permanent magnet array scanner. measurement method included.

Abstract In this chapter we are concerned with mesh generation methods and adaptivity issues. Nowadays, many techniques available to complete meshes of arbitrary domains for computational purposes. Planar, surface, volume meshing have been automated a large extent. Over the past few years, activities focused on adaptive schemes where features solution field must be accurately captured. To end, revisited in order capable completing high‐quality conforming these features. Error estimates...

The accuracy of many freehand medical procedures can be improved with assistance from real-time localization. Magnetic localization systems based on harnessing passive permanent magnets (PMs) are great interest to track objects inside the body because they do not require a powered source and provide noncontact sensing without need for line-of-sight. While effect number sensors in such has been reported, spatial design assembly is an open problem. This paper presents systematic approach...

Magnetic localization systems based on passive permanent magnets (PM) are of great interest due to their ability provide non-contact sensing and without any power requirement for the PM. Medical procedures such as ventriculostomy can benefit greatly from real-time feedback inserted catheter tip. While effects number sensors accuracy in has been reported, spatial design sensor layout largely overlooked. Here this paper, a framework determining an optimal assembly enhanced performance is...

Spherical robots have recently attracted significant interest due to their ability offer high speed motion with excellent locomotion efficiency. As a result of the presence sealed outer shell, its obstacle avoidance strategy has been simply "hit and run". While this is convenient specific geometry spherical robots, it however could pose serious issues when are small light. For portable on-board cameras, collision hard surface may damage robot or camera. This paper proposes novel compact...
