  • Method for analyzing an event such as a surgical intervention on a blood vessel
    Patent number: 7273456
    Abstract: A method of analyzing an event comprises the steps consisting in: gathering at least one series of measurements of a physical phenomenon associated with the event or likely to be associated therewith; from a predetermined mother wavelet ? and for at least one value of a predetermined parameter a, determining: the partition function Z(q,a) such that: Z ? ( q , a ) = ? b i ? ? ? T ? ? [ s ] ? ( b i , a ) ? q ?where: s is a signal representing variation in the measurements of the series as a function of a variable; T?[s](b,a)=1/a? ?((x?b)/a)s(x)dx where ? is the complex conjugate of the function ?(x) in an orthonormal base; and {(bi,a)}i is the set of local maxima in T as a function of a; the spectrum of the function ?(q) such that: Z(q,a)?a?(q) in the limit a?0+; the spectrum of the function D(h) such that: D ? ( h ) = min q ? ( qh - ? ? ( q ) ) and an index I(a) depending on said spectrum, which index is calculat
