Abstract

The present invention includes a toy for child undergoing magnetic resonance imaging (MRI) scan. The toy includes conducting components. When the conducting components of the toy move across the flux lines of magnetic field in the MRI scanner, eddy currents are induced. Eddy currents generate Lorentz force in conducting component of toy acting against direction of movement. Such resistance provides an exciting experience for the child in the MRI scanner bore space and helps calm the child`s apprehension about scanning.

TOY FOR CHILD IN MAGNETIC RESONANCE IMAGING SCANNER

                                                  

FIELD OF INVENTION

The invention generally relates to magnetic resonance imaging (MRI) and more particularly to a toy for a magnetic resonance imaging (MRI) scanner.

                                      

BACKGROUND OF THE INVENTION

In numerous instances, children need to undergo magnetic resonance imaging (MRI) scan for injuries and other medical conditions. A child tends to get anxious and apprehensive during the MRI scan due to various reasons including unfamiliarity, enormous size of the MRI scanner and space restriction inside the MRI scanner bore among others. Anxiousness makes movement during the scan difficult to curb. Movement of child during the MRI scan results in erroneous imaging.

Therefore, there is need in the art for a technique to avoid nerves and anxiousness of a child undergoing MRI scanning.

BRIEF DESCRIPTION OF THE INVENTION

The invention proposes a toy to be provided to a child undergoing magnetic resonance imaging (MRI) scan. The toy resists movement across flux line of magnetic field of the MRI scanner. Magnetic flux of the MRI scanner induces eddy currents in conducting components of the toy. Eddy current in conducting components of the toy generates Lorentz force acting against movement of the toy across flux lines of the magnetic field.

DETAILED DESCRIPTION OF THE INVENTION

The proposed invention discloses a toy for a child undergoing magnetic resonance imaging (MRI) scan. Attempts are made to encourage the child to play with the toy before and after MRI scanning. The toy resists movement across flux lines of magnetic field, thereby providing an exciting experience to the child. Such experience provides the child with familiarity with the MRI scanner and bore space.
