Background subtraction algorithms for videodensitometric quantification of coronary stenosis
Published Web Locationhttps://doi.org/10.1007/BF01213002
The determination of percent stenosis of coronary arteries is an important task in medicine. In this paper we discuss three different algorithms which can be used in conjunction with videodensitometry to measure this quantity. These algorithms may be used in subtracting the background under a vessel segment thus eliminating the need for a preinjection mask. Mathematical details of the algorithms and experimental results are presented. © 1988 Springer-Verlag.
