BOLDscreen 24 LCD for fMRI

BOLDscreen 24 350x350

Questions about the BOLDscreen 24?


BOLDscreen 24 has been engineered from the ground up to provide the superior image quality necessary for vision research: super high brightness, high contrast, high resolution visual stimuli.

Our BOLDscreen monitors are the only "MRI Compatible" MR Safe displays with no time lag, integrated sensor for luminance calibration and, of course, no interference with the scanner, even when positioned right at the exit of the bore.

"BOLDscreen provides an absolutely fabulous image and our testing shows no artefacts whatsoever." - The NeuroImaging Center, Rijksuniversiteit Groningen.

Superior image quality

BOLDscreen 24 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 24 with custom electronics deliver your stimulus direct to the screen - output is lag free and synchronous to the input video signal. Other "MRI Compatible" 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 24 incorporates a high resolution 1920 x 1200 IPS LCD 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 800cd.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 "MRI Compatible" displays, with BOLDscreen 24, what you put in is what you get out!

Easy to install and integrate

The 24" LCD 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.

An adjustable tripod is supplied as standard, and other styles of stand are available, or VESA compatible mounting points enable fixed installation on the wall of the scanner room.

BOLDscreen 24 can be used in conjunction with equipment form various other manufacturers, and integrates neatly with our eyetracker, audio system, response boxes and other Made for fMRI accessories.

No RF noise. No reduction in SNR. Operates beneath the noise floor of the scanner

We are the only manufacturer and vendor that provides an "MRI Compatible" MR 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.

BOLDscreen 24 has no observed effect on functional and structural MRI scans at 3T, even when located at directly at the exit of scanner bore, and no effect on displayed image whilst scanning.

30 days to try before you buy

We want all of our customers to be very happy with the equipment we supply. Please contact us to discuss your requirements, and we will help you to assess whether BOLDscreen 24 is the best solution for your research.

If you're still not sure, ask us for a 30 day trial: you place an order for BOLDscreen 24 in the normal way, then you have 30 days to try it out with your scanner, with the option to cancel if you decide that it's unsuitable in any way.
