ABSTRACT:
An entertainment system for use with a magnetic resonance imaging (MRI) device has a display panel and associated electronics which are mounted close to the MRI device and which are enclosed within a Faraday shield. A patient may be placed within the MRI device in a variety of positions and may view images from the display panel either directly or through a mirror, prism, or corner reflector. In order for the patient to view the images in the correct orientation regardless of the exact positioning, the display panel can display the images normally, with the images flipped from top to bottom, with the images flipped from left to right, and with the images flipped both from top to bottom and from left to right. The display panel is formed with a dark-colored focus area which forms a border around the display panel and which directs the attention of the patient toward the images on the display panel. The entertainment system indicates the various states of the MRI procedure through a set of lamps colored and arranged to simulate a typical traffic light. By using the traffic light configuration and coloring, patients can easily determine the state of the MRI procedure. The entertainment system calms the patient, distracts the patient from the MRI procedure, and makes it easier for the patient to remain still during the MRI procedure. As a result of the entertainment system, better quality images may be obtained with the MRI device.
