AVOTEC HOME / PRODUCTS / MOVIES / SILVER SCREEN



MR is a great imaging tool, but patients mostly hate it. So making your patients comfortable is a constant challenge. A great way to meet that challenge is to show your patients movies. And the Silver Screen™ movie system is the easiest and most reliable way to do it. Silver Screen™ is an LCD projection system. The Silver Screen projector is located at the rear of the magnet, with the projection screen, well away from your workflow. And the Silver Screen console is compact with simple controls, so it does not take away from your desktop, or your time.

The Silver Screen experience starts as soon as your patient walks up to the table, because they see their movie on the screen. And since there is no set up required, it is hassle free for you.

  • Silver Screen movies are a distraction

Patient motion always means repeated scans, especially for pediatric patients. Silver Screen can show DVDs, TV, or even iPOD material. More compliant patients can even decrease your sedation rates, especially for pediatric patients.

  • Silver Screen is safe

The Silver Screen projector sits outside the bore, so there are no worries about patient safety, MR artifacts, or SNR…for any scan….any coil…any magnet.

    
   
  • System Overview
  • Technical Specifications

Silver Screen™
Is a combined audio and visual system. It is comprised of a console (typically located at the MR control console), an LCD projector located at the rear of the magnet, an in-bore screen, and an audio transducer and headset located at the front of the magnet.

  • Up to four independent audio and/or visual inputs may be plugged into the console. These inputs are selected from the front panel of the console. Video inputs are displayed on the LCD monitor. Video inputs are composite video (NTSC/PAL). Computer inputs (VGA) can also be input by using an optional VGA to NTSC converter. This allows computer generated input for fMRI to displayed, for instance.

  • Communication from the patient to the technologist is via a dedicated microphone channel embedded in the patient headset. Communication from the technologist to the patient is over the gooseneck microphone mounted on the console.

 

The LCD projector
Is typically located at the rear of the bore to keep the projector out of the workflow. Because of its sophisticated RF shielding, the projector can be located as close to the bore as necessary without causing any interference….for any magnet, at any field strength.

  • The projector is powered via a DC power cable from the console (via the penetration panel). The video input signal to the projector is carried over fiber optic cable to ensure worry-free noise immunity.

  • The projector is mounted on a mobile stand, which allows the projector to be easily moved out of the way for magnet service. A unique locating-pin system on the stand makes it easy to reposition the projector.

  • The projector is supplied with a zoom lens to allow maximum flexibility in adapting to new coils, magnets or locations.

In-bore screen
Silver Screen uses a unique rear-projection screen that mounts at the end of the bore. The screen utilizes a simple Velcro mount and hinge arrangement that makes removal and installation a breeze. And since the screen is located close to the patient, many patients will not have to use corrective glasses to see the screen.

Audio transducer and headsets
The audio transducer is typically mounted on the front of the magnet with an adhesive bracket; the transducer can be easily removed to provide service access for the magnet. A tubing assembly connects the headset to the transducer. There are two types of headsets provided (full-coverage and stethoscopic) to provide the maximum noise reduction for each application.
