Introduction

The background of medical images typically contains small values. When an image is inverted, these small-valued voxels outside clinically relevant regions can become very large-valued. As a result, they appear bright or even white on the screen.

In a dark environment, especially when using a large display, these bright background regions can be uncomfortable to look at.
