Technology Platform




The MRI system of Catholic University Industry Academic Cooperation Foundation has been developed to resolve problems of the prior dental clinic devices including CT imaging device, panorama imaging device and cephalo imaging device, and improve prior MRI devices. The core technology of Catholic University Industry Academic Cooperation Foundation is to provide a RF coil unit, a head fixing unit and a magnetic resonance imaging (MRI) system having the same for use of dental clinic capable of performing magnetic resonance (MR) imaging of soft tissue such as teethridge and dental nerve tissue as well as teeth and dentary bone.




Background and unmet needs




The prior dental inspection devices such as CT imaging device and panorama imaging device have an advantage to rapidly obtain images of teeth status. However, they also have a disadvantage of not able to obtain sufficient anatomical images of soft tissue such as teethridge and dental nerve tissue. The MRI device makes it possible to obtain sufficient anatomical images of soft tissue such as teethridge and dental nerve tissue. However, MRI devices are not generally used for dental diagnosis including inspection of soft tissue such as teethridge and dental nerve tissue due to the inspection complication, device size and device expensiveness.




Discovery and Achievements




The MRI system can reduce the maintenance cost as compared to prior MRI systems which employ super-conductive magnets since their first and second polar structures are comprised of N pole and S pole permanent magnets, respectively. The MRI system also makes it possible for a subject to be inspected comfortably since it is sufficient to inspect the subject by locating the only head of the subject to be inspected on the imaging space without locating the whole body of the subject to the closed inspection table of MRI device. The MRI system can prevent detection of incorrect signal due to movement of the subject to be inspected during inspection by using the head fixing unit, thereby obtaining more accurate MR images. The MRI system can provide the subject with improved inspection convenience by supplying the cradle to the subject, so that the subject can be conveniently inspected while sitting at the cradle which is moving upward and downward during the inspection.
