Assign 16-bit grayscale pixels to Texture2D

Hi guys, I'm trying to render a dicom image with Texture2D, which is in 16-bit grayscale. I have loaded the pixel bytes already. This is what I got (with unlit/texture shader):



I divided each pixel by 0xFF to make it 8-bit and put it into the RGB channel of a Color32.
However, when I convert the image with Photoshop and import into Unity, this is what it renders:



I'm trying to figure out where I did wrong. I didn't find any texture format supporting 16-bit grayscale, so I'm trying to compress the 16-bit value into 4 channels of 32-bit ARGB (which is 8-bit each). Any suggestions on this problem?

 

Unity can take 16 bit greyscale images and keep them in that format, at least since 2018.

Save the 16 bit greyscale image to a PNG, PSD, or TIF in the assets folder. Select it, and change the type to Single Channel. Change the format to R 16 bit.

 

Hi, Thank you for your reply. I found the import settings for the texture generated, but I'm trying to construct the 2d texture from the byte array I extracted from the dataset. Is there anything similar in scripts? I found R16 in the Textureformat, but that seems only works for the red channel.

 

Update:

I found the standard to convert pixel data to 8-bit grayscale colors for DICOM:
https://www.dabsoft.ch/dicom/3/C.11.2.1.2/
which generates the correct output.

 

@SimonJ9, The site you posted is no longer available. Have you had updates on this issue? I'm having the same problem... How did you solve it?
Thanks a lot!
