Designed for 60 and 70cm bores, the premium 32" 1920x1080 widescreen LCD display features up to 16-bit RGB colour control, 1400:1 contrast ratio and 120Hz panel drive.
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 32 has a high-bandwidth, dual-link DVI input and can be driven just like the LCD monitor on your desk, with standard software tools. Simply run the provided 30m optical fibre cable through a waveguide and plug the DVI transmitter into your control room host computer, for high fidelity, noise-free displays.
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 dual-link DVI input will synchronise to a 1920x1080 @ 120Hz video signal and will output video at the same rate.
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!
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 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 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.
"BOLDscreen performs exceptionally and was very easy to configure. The image is bright, clear and visibly excellent. A definite must-have for our studies! We will recommend it to other groups."
"BOLDscreen provides an absolutely fabulous image and our testing shows no artefacts whatsoever."
"We are using the BOLDscreen and it is going well. We installed it at the head of the scanner. There is a gap of a metre or so between the bore opening and the head of the scanner bed (and screen), but we have a full field of view."
"We've got the standard BOLDscreen connected to ViSaGe and are very happy with it so far. We've had a difficult time trying to calibrate projectors in MRI labs in the past, but this system is good. We just calibrated BOLDscreen by moving it into the control room, still connected as normal to the ViSaGe, using a CRS ColorCAL and then checking with a Minolta CS100. It was straightforward to adjust the overall luminance level which is helpful for calibration."
MR safe prescription glasses suitable for use in MRI, fMRI, MEG, PET, CT and EEG environments. No metallic components. Easy push fit interchange system with -6 to +6 dioptre Rx/lenses in 0.5 dioptre increments.
LiveTrack AV for fMRI is an affordable video eye tracking system which provides real-time estimates of eye rotation, Direction of Gaze coordinates and pupil size. A live video stream from the eye tracking camera is available concurrently with the data so you can visually monitor and check your observer's behaviour throughout the experiment.
BOLDfonic delivers high-fidelity acoustic stimuli for fMRI while also attenuating scanner noise. Our electro-dynamic driver technology uses the magnetic field of the MRI scanner to drive the headphone membranes. This results in powerful speakers with an excellent frequency response across a wide dynamic range. A novel USB sound processor with automated synchronous triggering capabilities and a fully–loaded amplifier system provide all the controls you need for rigorous multimodal EEG/fMRI studies.
