Abstract

A technique that provides a wide bore illusion in an MRI scanner for reducing claustrophobia in a patient is disclosed The technique includes providing two dimensional 2D and three dimensional 3D patterns the bore of the MRI scanner to create a visual illusion of a wide bore The 2D and 3D patterns around the bore create an optical illusionary effect and the patient perceives the bore wider than real size of the bore Various optical illusion techniques such as Ebbinghaus optical illusion bulging checker board illusion Mueller Lyer illusion Ponzo illusion and image transformation techniques like inverse perspective transformation and mapping may be used

WIDE BORE ILLUSION IN MAGNETIC RESONANCE IMAGING (MRI) SCANNERS

BACKGROUND

 

The present disclosure relates generally to a magnetic imaging (MRI) scanner and more particularly to two dimensional and three dimensional patterns provided around the bore of the MRI scanner to create a wide bore illusion.

Claustrophobia is one of the many acute distress symptoms found in patients undergoing an MRI scan. Lying on a cradle inside or even approaching the bore of an MRI scanner may induce claustrophobia during or before the scan respectively.

Various conventional techniques are used for alleviating claustrophobia in patients. One conventional technique includes constructing a wider bore. Another conventional technique includes providing a front fascia of the MRI scanner magnet that is different from one provided in regular MRI scanners by providing different color themes and/or painting the front fascia with characters that may have a visual appeal for the patient. For example, painting cartoon characters on the front fascia to prevent claustrophobia and other distress symptoms in children undergoing MRI.

Further, there are various conventional techniques that may alter space perception by optical illusions. One such technique involves using 2 dimensional (2D) patterns of optical illusion in 3 dimensional applications. Another technique involves creating illusions by stereoscopy.

It would be desirable to have a technique that provides a wide bore illusion in the MRI scanner for reducing claustrophobia in patients.

BRIEF DESCRIPTION OF DRAWINGS

Figure 1 depicts a pattern printed on flexible vinyl sheets and bonded to a bore and a front canopy of an MRI scanner.

Figure 2 depicts the pattern projected onto the bore and the front canopy using a projector.

Figure 3 depicts different patterns modified to right proportion, placement, color and contrast for disposing them around the bore.
