Improved visualisation of brain arteriovenous malformations using color intensity projections with hue cycling [article]

Keith S. Cover
2017 arXiv   pre-print
Color intensity projections (CIP) have been shown to improve the visualisation of greyscale angiography images by combining greyscale images into a single color image.  ...  An angiogram of a brain is used to demonstrate the substantial improvements hue cycling brings to CIP images.  ...  Disclosure: The authors employer, the VU University Medical Center in Amsterdam, is pursuing patents on color intensity projections covering applications in astronomy, medical imaging, and other fields  ...
