Abstract

A method of quantifying progression of pregnancy, comprising:a) Illuminating a uterine cervix with polarized light having a wavelength comprised between 600 and 1100 nm;b) Acquiring a plurality of images of the illuminated uterine cervix through a polarization state analyser in respective analysing states;Steps a) and b) being performed either once or a plurality of time using polarized light having different polarization states;c) From the acquired images, computing a depolarization parameter over a region of interest of the uterine cervix; andd) Quantifying the progression of the pregnancy from said depolarization parameter.An apparatus, based on a colposcope fitted with a controllable polarization state generator, a controllable polarization state analyser and a suitably-programmed computer, for carrying out such a method.A computer program for carrying out such a method.
