Presented herein are systems and methods that provide for improved computer aided display and analysis of nuclear medicine images. In particular, the systems and methods described herein offer improved interactive adjustment of intensity windowing for display of nuclear medicine images. The interactive intensity window selection tools described herein utilize a nonlinear scaling function that maps user adjustments to positions of displayed indicator widgets on a scale to intensity window thresholds. The form of the scaling function increasingly magnifies user adjustments at the upper range of the scale, but remains linear at the lower end. The intensity windowing tools presented herein allow the user to adjust intensity thresholds over a full range of intensities encountered in an image, up to the maximum value, while still preserving fidelity in an important range that includes lower intensities.
