"The MedGemma image encoder accepts RGB, 8-bits per channel images as input. MedGemma has also been trained to interpret CT images where the RGB channels of input images correspond to a novel windowing representation to enable it to interpret multiple representations of CT imaging simultaneously. Specifically, MedGemma 1.5 has been trained with the components defined as follows:\n",
" * Red (component 0): Wide window; range: -1024 HU ([air](https://en.wikipedia.org/wiki/Hounsfield_scale)) to 1024 HU ([above bone](https://en.wikipedia.org/wiki/Hounsfield_scale))\n",
" * Green (component 1): Soft tissue window; range: 135 HU ([fat](https://en.wikipedia.org/wiki/Hounsfield_scale)) to 215 HU ([start of bone](https://en.wikipedia.org/wiki/Hounsfield_scale))\n",

" * Blue (component 2): Brain window; range: 0 HU ([water](https://en.wikipedia.org/wiki/Hounsfield_scale)) to 80 HU ([brain](https://en.wikipedia.org/wiki/Hounsfield_scale))\n",

" Since each of the RGB channels in the prompt images corresponds to a windowing prompt, imaging prepared using this method will visually appear in color.\n",
