Imaging modality using penetrating radiations

摘要

Systems and methods which use penetrating radiation to obtain novel type of information about objects of interest. This information may be represented as novel type of image. In the present embodiments, penetrating radiation is directed through the object of interest. The attenuated radiation emerging from the object of interest is detected by at least one detector. A plurality of measurements is collected. At least one statistical parameter describing variations of the measurements may be calculated and used for reconstructing an image representing fluctuations of the attenuation of the penetrating radiation in the object of study. At least one other statistical parameter representing the mean attenuation image, the error of the fluctuation image, or the error of the mean attenuation image may also be calculated and used to reconstruct images of the object of interest.

1. A method for imaging an object of interest using penetrating radiation, comprising:
(a) positioning a source of penetrating radiation and a radiation detector externally of the object of interest and with the object of interest positioned therebetween; (b) repeatedly measuring the penetrating radiation generated by the source of penetrating radiation and passing through the object of interest along each of at least one linear path extending from the source of penetrating radiation to the radiation detector and intersecting the object of interest, by: (i) exposing the object of interest to the penetrating radiation thereby allowing the radiation to pass through said object, and (ii) detecting the penetrating radiation which passes through the object of interest along each of the at least one linear path, thereby to generate a plurality of measurements for each of the at least one linear path; (c) processing the plurality of measurements for each of the at least one linear path to obtain at least one statistical parameter capable of describing a width of a temporal distribution of the plurality of measurements for each of the at least one linear path, and (d) reconstructing the image of the object of interest based on the at least one parameter describing the distribution of the plurality of measurements, thereby obtaining images of the object of interest.
