The acceptable subject to detector distance is reduced or increased, spatial resolution is improved, tracer dose or concentration is reduced, subject radiation exposure is reduced and / or scanning time is reduced.

The present invention includes a filtering apparatus for a CT imaging system or equivalently for an x-ray imaging system. The filtering apparatus may be translated along a first axis or a transverse axis to with respect to an attenuation pattern of a subject during an imaging session to reduce radiation exposure to anatomical regions of the subject sensitive to radiation exposure and / or regions from which data is not being acquired.

The invention concerns a 5-aminolevulinic acid ester (E-ALA) solution for producing a pharmaceutical preparation useful for diagnosing and / or treating tissue and / or cell pathologies by local radiation exposure using radiation emitted by a light source energy followed, in the case diagnosis, by detection of fluorescent protoporphyrin IX (Pp1X). The E-ALA concentration in the solution is less than 1% and ranges between 0.01% and 0.5%. The low E-ALA concentration in the solution increases Pp1X synthesis and homogenises its distribution in the cell layers while highly reducing the secondary toxicity for the treated cells.
