Questions about BOLDscreen 23?

 

BOLDscreen 23 is a legacy product that provides a simple, cost-effective way to present visual stimuli for 3T fMRI.

Like our other BOLDscreen LCD monitors, it's an "MRI Compatible" MR Safe display with no time lag and, of course, no interference with the scanner, even when positioned right at the exit of the bore.

Though not available for purchase any more, the BOLDscreen 23 is still fully supported by Cambridge Research Systems. This legacy page will include technical data, downloadable firmware updates as well as installation information. For alternatives to the BOLDscreen 23, please visit the BOLDscreen 32 and BOLDscreen 24 product pages.

Superior image quality

BOLDscreen 23 is an affordable LED LCD monitor which is designed to make it easy to present simple visual stimuli for experiments using fMRI.

The monitor 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 23 with custom electronics which 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 23 incorporates a high resolution 1920 x 1080 IPS LCD panel with 8-bit colour resolution, providing a true-colour 16.7 million colour display and contrasts of up to 800:1

Unlike other "MRI Compatible" displays, with BOLDscreen 23, what you put in is what you get out!

Easy to install and integrate

Our in-the-room approach is significantly easier to setup, calibrate and maintain than a projector or goggle system. BOLDscreen's 23" display is designed to provide a large field of view when sited at the rear of the 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. The VESA compatible mounting points also enable fixed installation on the wall of the scanner room.

BOLDscreen 23 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 23 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 23 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 23 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.
