BOLDscreen 24" Monitor für fMRT

Art.Nr.:
M0131
Preis auf Anfrage

Other MRI-compatible LCD displays used for patient comfort in clinical fMRI typically use TV technology which deliberately interpolates the input and introduces lag, producing an image which may look easy on the eye, but is unsynchronised and smeared with respect to the input, and therefore of limited use for precision scientific applications.

BOLDscreen is different. Our custom electronics deliver your stimulus direct to the screen, so that what you put in is what you get out! Also, we are the only manufacturer and vendor that provides a MRI-safe LCD monitor that you can site anywhere inside the MRI room, even directly at the exit of the rear of the magnet bore so that you can maximise the visual field of view. 

Light Output

  • SuperBright LED matrix backlight produces images up to 1000cd.m-2
  • Native 8-bit colour resolution
  • 1000:1 typical contrast ratio
  • 5ms average grey-to-grey response time

Display

  • 24" 1920 x 1200 full colour H-IPS LCD running at fixed 60Hz frame rate
  • No internal video scan conversion means that light output is lag-free and completely synchronous to the input video signal
  • No dropped or interpolated frames: what you put in is what you get out!
  • Digital DVI video input delivers high fidelity noise-free displays

Installation

  • Compatible with 1.5T and 3T scanners
  • View using standard headcoil mounted mirrors
  • Images can be viewed flipped or inverted
  • All aluminium enclosure provides passive cooling and MRI-compatible shielding
  • 20m fibre optic cable between the control room host computer and the enclosure guarantees artifact free scans
  • Low voltage DC power supply for controlled, safe installation inside the scanner room
  • VESA compatible mounting points enable fixed installation on the wall at the rear of the scanner
  • MRI-compatible floor standing tripod included
