BOLDscreen 24


BOLDscreen MR Safe display for 3T fMRI – We have engineered BOLDscreen from the ground up, to provide the superior image quality necessary for vision research: super high brightness, high contrast, high resolution visual stimuli. It’s the only display with no time lag, integrated calibration and, of course, no interference with the scanner, even when positioned right at the exit of the bore.

Superior image quality:
BOLDscreen has a digital DVI input and can be driven just like the LCD monitor on your desk, with standard software tools. Simply run the provided 20m optical fibre DVI cable through the waveguide and plug into your control room host computer, for high fidelity, noise-free displays.

We have designed BOLDscreen with custom electronics deliver your stimulus direct to the screen – output is lag free and synchronous to the input video signal. Other LCD displays designed for patient entertainment in MRI typically use TV technology and video scan conversion which deliberately interpolate the input, 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 incorporates a high resolution 1920 x 1200 IPS panel with native 8-bit colour resolution, providing a true-colour 16.7 million colour display and contrasts of up to 1000:1

To achieve the image quality required for scientific visual stimulation, we illuminate the panel with a unique super bright, LED matrix backlight. This produces highly saturated chromatic displays at up to 1000cd.m-2: many times brighter than any normal display. The backlight has excellent spatial uniformity, typically 2% over central 75% of display area. We have also incorporated real-time calibration that ensures consistent luminance immediately from switch on, and automatically compensates for the usual drifts in brightness due to temperature changes and ageing. Unlike other displays, with BOLDscreen, what you put in is what you get out!

Easy to install and integrate:
BOLDscreen’s 24” display is designed to provide maximum field of view when sited at the rear of a 60cm bore and viewed via headcoil mounted mirrors. The image can be automatically left-right flipped, to cancel the flip caused by the mirror. The low voltage DC power supply is safe to install within the scanner room, and the fibre optic DVI video input passes through the waveguide, to your computer in the control room.
