Abstract

A magnetic resonance imaging MRI head neck imaging coil with an integrated tilt capability is disclosed The head neck imaging coil includes an anterior head neck array coil and a posterior head neck array coil The anterior and posterior head neck array coils are configured to cover head and neck regions of a patient during an MRI examination Further the posterior head neck array coil includes a set of pivotally coupled lower and upper sections at least one intermediate section and a mechanism for varying angular spacing between the lower and upper sections

ADJUSTABLE MAGNETIC RESONANCE IMAGING (MRI) HEAD COIL

BACKGROUND

The present invention relates generally to a magnetic resonance imaging (MRI) system and more particularly to an adjustable MRI head coil.

Construction of head and neck posterior imaging coils in conventional magnetic resonance imaging (MRI) systems is unsuitable for accommodating patients suffering from various conditions, such as, Torticollis, Kyphosis and similar neck and spine disorders. In order to provide comfortable head and neck posterior imaging coils, MRI system manufacturers have introduced an accessory to help adjust tilt angle of the posterior coil.

However, the conventional solution of a lose tilt unit offered as an additional accessory results in added complexity while using the MRI system and managing the patient. This additional accessory is required to be separately stored, handled, cleaned or sterilized in addition to an essential set of head and neck anterior and posterior coils and a host of other radiofrequency (RF) coils. Consequently, preparative workflow steps increase which increases associated effort and time. Due to the complexity involved in locating and sequentially stacking and un-stacking of the tilt accessory and the posterior and anterior head neck coils, before, during and after the procedure, the technicians are unnecessarily stressed. The added steps and complexity result in poor asset and staff productivity and increase procedure time, inconvenience and discomfort for the patients. Sometimes, non-obvious accessibility to the added steps discourages technicians from performing these steps.

It would be desirable to have a simpler and a more efficient technique to position patients with neck and spine conditions for MRI imaging.
