Comparison of the reconstructed CT slices of a rat head with iodine injection. (a) CT reconstructed image (raw signal) of a 9L brain tumor bearing rat after iodine injection. (b) CT reconstructed image of the phase-extracted signal. (c) Comparison of the signal-to-noise ratio (defined as the ratio between mean intensity and standard deviation of the contro-lateral healthy tissue). (d) Comparison of the contrast between tumor and normal tissue obtained in our images. The contrast is defined as the ratio between the difference of mean intensity in the healthy and tumoral tissue versus the noise measured as the standard deviation of the contro-lateral tissue. Symbols represent the individual value for one rat while horizontal bars are means and standard deviations.
