A measurement
system and method are presented for use in detecting a predetermined condition of a patient's ear indicative of a certain
disease such as SOM and SOM. The
system comprises an optical measuring unit and a
control unit connectable to the output of the measuring unit. The optical measuring unit is configured and operable for irradiating a
region of interest in a patient's ear with incident light including at least two different wavelengths, detecting light responses of the
region of interest to said at least two different wavelengths, and producing measured data indicative thereof. The at least two different wavelengths are selected such that the
light response of the
region of interest to at least one first
wavelength is substantially independent of said predetermined condition and the
light response to at least one second
wavelength is affected by said predetermined condition. The
control unit is operable for receiving and
processing the measured data to generate output data indicative of the measurement results. The
control unit is configured and operable for controlling operation of the optical measuring unit, and for receiving the measured data and
processing it to generate output data indicative of whether or not said predetermined condition exists. The control unit comprises a memory utility for storing predetermined reference data indicative of the
light response of the region of interest while in a healthy condition of a patient's ear; a
data processing and analyzing utility preprogrammed for
processing and analyzing the measured data by determining a relation between the measured light responses and the corresponding reference data.
