While MRI is considered to be a safe imaging technique, it is not without hazards. The magnet field will attract many ferromagnetic metals in an uncontrolled fashion and cause them to fly towards the magnets bore and turning them into high velocity projectiles. The bore of the magnet is where the fringe field is strongest, as all the lines of force are constricted and their relative strengths heightened. Various objects can be considered projectiles. for hadron . therapy.  . . Joseph V. Minervini. 1. , Alexey Radovinsky. 1. , Craig E.

This book is the first to treat the engineering of superconductivity. It provides a complete theoretical basis for the quantitative engineering design of superconducting magnet systems, from the small instrument magnets used as everyday research tools to the very large magnet systems used to work on thermonuclear fusion and magnetohydrodynamic power generation. The author devotes particular attention to the problem of stabilization, a crucial factor in the design process due to its bearing on the overall reliability of the completed system, and also describes the essential features of field and stress calculation. Engineers and physicists involved in the design of systems utilizing superconducting magnets will welcome this publication. This book is the first to treat the engineering of superconductivity.
