Abstract :
A digital brain phantom was created from rat brain autoradiographic (AR) data for use in emission computed tomography studies. The animal tissue was radio-labeled with [14C]-2-deoxyglucose, a functional analog of the PET agent [ 18F]-fluro-deoxyglucose. Following sacrifice of the animal, serial tissue sections were cut at 20 μm thickness, digitized, and calibrated to represent the ground truth 2D relative spatial distribution of radionuclide within the tissue. A 3D representation was achieved by digital alignment of the serial AR images to corresponding video blockface images acquired at the time of cutting. In addition, a magnetic resonance data set was co-registered to the AR and blockface data using the AIR algorithm. This paper is concerned with outlining the details of construction for this phantom
