Description

Technical Field

[0001] This utility model relates to the field of magnetic resonance imaging technology, and in particular to a coil device for magnetic resonance imaging. Background Technology

[0002] Magnetic resonance imaging (MRI) devices are primarily used for precise imaging examinations of human structures to aid in the diagnosis of related diseases. In current technology, to facilitate the examination of local organs, MRI devices are gradually becoming smaller and more specialized. Head-mounted MRI devices are now available, allowing for the examination of the head and ears. There are also devices specifically designed for ear or temporomandibular joint examinations. Most of these are one-piece structures, only suitable for fixed models, and do not allow for adjustment of the internal coils. Furthermore, the varying degrees of temporal bone pneumatization and development among different patients lead to differences in head circumference, and some patients have extensive post-operative coverings or bandages, limiting the coverage area of ​​existing coils and hindering adjustment, thus affecting image quality. The rigid materials used can also cause discomfort for patients. The connectors between the coils are difficult to disassemble and clean, and the accumulation of sebum and other secretions on the scalp can easily lead to cross-infection during examination and cause patients to develop resistance. Therefore, there is an urgent need to improve these devices. Utility Model Content
