A technique to leverage psychology illusion effect to improve patient experience during magnetic resonance (MR) exam is disclosed. The technique creates an illusion to change the psychology of a patient, such that, the patient feels that the magnet bore is bigger in size than the actual size of the magnet bore. The proposed technique leverages an illusion design and includes painting an illusion pattern or other space illusion pattern on the magnet bore. The magnet bore may be carved, or implanted in some other fancy forms to create a better visual effect than that created by painting for the patient lying inside the magnet bore. The technique may also leverage Ebbinhaus illusion to make decoration holes around the magnet bore.
The present invention relates generally to a magnetic resonance (MR) system and more particularly to a technique for expanding magnet core dimension by using illusion design in the magnet bore.
Generally, size of a magnet bore in a magnetic resonance (MR) system is critical to patient experience during MR exam. A typical magnet bore has a diameter in the range of 60 cm to 70 cm. During MR exam, head of the patient is moved into the magnet bore. Due to narrow space of the magnet bore, the patient feels nervous and anxious, and some even feels difficult to breath and panic when kept inside the magnet bore. Due to small size of the magnet bore, patients are reluctant to undergo MR examination. Also, many patients do not feel well during scanning time of MR exams. Such claustrophobic like symptom in patients is related to psychology of the patient. Further, magnet bore size design is connected to cost of a magnet. Expense incurred on expansion of the magnet bore is huge amount if physical design requires modification, as expense of extending size of a magnet core is very high.
There are several techniques known in the art that creates an illusion and provides simulation effect of an object. For example, a conventional technique includes a flame simulating assembly that is adapted for storing objects and for affecting a temperature of the objects. The flame simulating assembly includes a flame image subassembly for providing one or more images of flames. The flame image subassembly includes one or more light sources and a screen positioned in a path of light from the light source. However, such and other conventional techniques require additional components for simulation. Also, the techniques do not find application in the MR system design. In case the conventional techniques are used with MR system, a high expense is required to assemble the components in the magnet bore of the MR system.
Therefore, it would be desirable to have a cost effective and efficient technique that improves patient experience during magnetic resonance (MR) exam.

Generally, illusion is a distorted perception under specific condition. Illusion can be identified out, but even after the illusion is identified, psychology perception cannot be avoided. Such a symptom is used to change perception of the patien...
