About

These are sample NIfTI images designed for evaluating viewing tools like NiiVue. These are intentionally low-resolution images to reduce file size and ensure compatibility with old computers and mobile devices. Larger but higher quality images are available by downloading the Extra Sample Images. Further examples are available in the VolumeRenderingData repository.
