Claims
- 1. A method for generating an absorption image of an object comprising the steps of
- irradiating the object with a time-domain source of radiation,
- measuring a transmitted intensity due predominantly to diffusively scattered radiation wherein said transmitted intensity is related to an absorption function by an integral operator, and
- directly reconstructing the image by executing a prescribed mathematical algorithm, determined with reference to said integral operator, on said transmitted intensity, said step of directly reconstructing including the step of computing a hitting density.
- 2. The method as recited in claim 1 wherein the step of irradiating the object includes the step of successively irradiating the object with different wavelengths.
- 3. A system for generating an absorption image of an object comprising
- time-domain radiation source means for irradiating the object,
- detector means for measuring a transmitted intensity due predominantly to diffusively scattered radiation wherein said transmitted intensity is related to an absorption function by an integral operator, and
- means for directly reconstructing the image by executing a prescribed mathematical algorithm, determined with reference to said integral operator, on said transmitted intensity, said means for directly reconstructing including a means for computing a hitting density.
- 4. The system as recited in claim 3 wherein said source means for irradiating the object includes means for successively irradiating the object with different wavelengths.
