Abstract
A method measures a perfusion wave upstroke associated with leg perfusion dynamics, the perfusion wave upstroke including two phases, an initial slow phase and a fast-rising phase, and using prolongation of the slow phase to detect a presence of arterial stenosis and to assess stenosis severity.
Claims16
A method comprising:
- measuring a perfusion wave upstroke in a perfusion wave associated with leg perfusion dynamics, said perfusion wave upstroke comprising two phases, an initial slow phase, which ends at a maximum perfusion acceleration point, and a fast-rising phase, which begins at the maximum perfusion acceleration point,
- graphically or numerically displaying prolongation of a duration of said initial slow phase, called a slow phase duration (SPd), and
- graphically or numerically displaying a presence of arterial stenosis and graphically or numerically displaying a numerical quantification of severity of the arterial stenosis as a function of said prolongation of said SPd.
