Luminance values for the MRI compatible screen
Figure - Luminance values for the MRI compatible screen measured per channel. The values are in cd/m2.
MATLAB files of luminance measurements
The following MATLAB files contain the luminance values for the MRI compatible screen measured per channel. Column one - presented values per channel, column two - measured valued for the red channel, column three - measured valued for the green channel, column four - measured valued for the blue channel.
The following two files contain the estimated gamma values and LUTs for RGB and gray, respectively.
