Fig 1.
Schematic diagrams describing the connection between OLED display and PC.
Fig 2.
(a) OLED with shield box, and (b) the detailed structures of the shield box. The shield box contains the OLED itself and the video converters without additional shielding between the individual units.
Fig 3.
System set-up to measure noise with LNA board and field probe.
Fig 4.
The schematic of visual angle, display width and distance.
Fig 5.
The installation of the OLED display inside bore.
(a) A schematic diagram and (b) a photo of the OLED display installed on the head coil.
Fig 6.
Measured noise emission of the OLED display.
The display is cantered on the Larmor frequency of the MRI system (123.25 MHz) and covers a bandwidth greater than the bandwidth used in the fMRI acquisitions.
Table 1.
Calculated visual angle of dual OLED compared to that of commercial screens mounted outside the scanner bore.
Fig 7.
SNR evaluation with the display turned off (a) and the display in operation (b).
Fig 8.
BOLD activation when stimulating the visual cortex using the display presented here and a checker-board block paradigm.
Hemispheric asymmetries as observed for LCD activation in volunteers with a dominant eye in [7] are not visible in the activation pattern acquired here.
