Classification: CPC A  G | IPC A  G

Claim 1:
2. The apparatus (100) according to claim 1, wherein said computer (24) is configured to calculate respective correlation coefficients of said frequency spectra (43i, 44i, 47, 48) associated with said cortical (40′) and/or said trabecular (41′) parts of said patient's bone region (21), with said memorized:
at least one healthy reference spectrum (52) associated with at least one healthy patient,
at least one intermediate reference spectrum associated with an intermediately-healthy patient,
at least one pathological reference spectrum associated with a pathological patient, and to select, from said frequency spectra (43i, 44i, 47, 48) associated with said cortical (40′) and/or said trabecular (41′) parts of said patient's bone region (21), a number of valid spectra, wherein at least one of said respective correlation coefficients exceeds a predetermined threshold value;, and to define a diagnostic parameter selected from the group consisting of:
said percentage of healthy or pathological or intermediate valid spectra, respectively;
a parameter according to the average value of said correlation coefficient of said valid frequency spectra;
a statistic parameter or a combination of statistic parameters that describe a distribution of values of said correlation coefficients of said valid spectra;
a diagnostic parameter associated to a reference spectrum (52) selected among a plurality of reference spectra that represent specific pathology seriousness levels.
