We describe an experimental setup for time-resolved diffuse optical tomography that uses a seven-channel light guide to transmit scattered light to a streak camera. This setup permits the simultaneous measurement of the time profiles of photons reemitted at different boundary sites of the objects studied. The instrument, its main specifications, and detector-specific data analysis before image reconstruction are described. The instrumentation was tested with phantoms simulating biological tissue, and the absorption and reduced scattering images that were obtained are discussed.
The use of thermoluminescence as a method for the dosimetry of ionising radiation has been established for many decades and has been unquestionably successful. It is therefore difficult to imagine how any new technique could easily supplant it. Perhaps optically stimulated luminescence dosimetry should not be characterised as an entirely new technique, but rather a development of the well established technology that may be considered superior in some respects. As is obvious from the tenor of this debate, our two participants are longtime colleagues who have had numerous discussions on this topic. No doubt, many of us will have similar discussions in our own institutions as we weigh the advantages and disadvantages of TLD versus OSL.
