Abstract
The present invention provides methods and systems for 3D imaging of in vivo and ex vivo tissues. The disclosed systems and methods employ an autoradiographic approach where particles emitted by a radioactive composition within the tissue are detected. Once detected, a 3D representation of the source of particles within the tissue is reconstructed for viewing and analysis.

75. A method for reconstructing a 3D distribution of a source of particles, the method comprising the steps of:
-
providing said source of particles, wherein said particles comprise beta particles, alpha particles, positrons, or conversion electrons; repeating, for each of a plurality of said particles from said source, the steps of; recording an image of a particle track with a particle track detector; determining attributes of said particle track using said particle track image; and storing said attributes of said particle track; thereby generating attributes for each of said plurality of particles from said source; and reconstructing said 3D distribution of said source of particles using said attributes for each of said plurality of particles. - View Dependent Claims (76, 77, 78, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95)

96. A method for imaging a source of particles within a tissue sample, the method comprising the steps of:
-
recording images of a plurality of particle tracks with a particle track detector; determining attributes of said plurality of particle tracks from said images; storing said attributes of each of said plurality of particle tracks; repeating said detecting, determining and storing steps for a plurality of depths within said tissue sample, wherein said plurality of depths are obtained by removing one or more layers of said tissue sample and wherein removal of each layer of said tissue sample exposes a deeper surface of said tissue sample, thereby generating particle track attributes for a plurality of particles from said source at a plurality of depths within said tissue sample; and reconstructing a 3D image of said source of particles using said particle track attributes for a plurality of particles from said source at a plurality of depths within said tissue sample and said plurality of depths within said tissue sample. - View Dependent Claims (97, 98)

99. A device for imaging a source of particles comprising:
-
a particle track detector for recording images of detectable signals generated along particle tracks in an active material, wherein said detectable signals are generated by an interaction of a particle from said source with said active material, wherein said particle comprises a beta particle, alpha particle, a positron or a conversion electron; and a processor positioned in data communication with said particle track detector, wherein said processor is configured for; analyzing a plurality of images of detectable signals generated along particle tracks of a plurality of particles in an active material to determine attributes of said plurality particle tracks; and reconstructing a 3D image of said source of particles using attributes corresponding to all of said plurality of particles. - View Dependent Claims (100, 101, 102, 103, 104)
