Made for fMRI by Cambridge Research Systems

Superior image quality

BOLDscreen 32 has a high-bandwidth, digital video input and can be driven just like the LCD monitor on your desk, with standard software tools. Simply run the provided 30 meter optical fibre cable through a waveguide and plug it into the BOLDscreen 32 AVI video matrix switch.

We have designed BOLDscreen 32 with custom electronics which deliver your stimulus direct to the screen - the 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.

The BOLDscreen 32 design incorporates a premium 32" 1920x1080 IPS LCD panel with native 10-bit RGB colour resolution and a stunning static contrast ratio of 1400:1 (measured with the backlight on; [1 1 1]:[0 0 0] RGB contrast ratio). The panel features 120Hz panel drive capability, and a fast 5ms grey-to-grey response time. The digital video input will synchronise to a 1920x1080 @ 120Hz video signal and will output video at the same rate. The BOLDscreen 32 AVI supports inputs at other resolutions and frame rates, including from sources like iPads, Blu-ray disc players, and Internet streaming media players like the Apple TV.

To achieve the image quality required for scientific visual stimulation, we illuminate the panel with a custom LED backlight. This produces highly saturated chromatic displays and a peak white output at up to 350cd.m^-2 (other calibrated white settings are simple to set in the device configuration file). We have also incorporated a sensor for 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 32, what you put in is what you get out!

Easy to install and integrate

The 32" LCD display is designed to provide maximum field of view when sited at the rear of a 70cm 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 installed through the penetration panel, and the fibre optic video cable passes through the waveguide, to the BOLDscreen 32 AVI located 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 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 has no observed effect on functional and structural MRI scans at 3T or 7T, 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 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 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.
