Current configuration does not allow embedding of the file atlas_rendering_72x164.swf because of its mimetype application/x-shockwave-flash.: atlas_rendering_72x164.swf
Our mouse atlas can be used to generate simulation images for PET and optical reconstructions. Here, we provide the Linear Attenuation Coefficients which were computed using the Mass Attenuation Coefficients of corresponding materials (Hubbell and Seltzer, 1996) that are assigned to the tissues in the atlas image to create an attenuation coefficient image for PET simulation.

For optical simulations scattering and absorption coefficients are computed using the optical properties reported in
Alexandrakis, G., Rannou, F. R., and Chatziioannou, A. F. (2005). "Tomographic bioluminescence imaging by use of a combined optical-pet (opet) system: A computer simulation feasibility study". Phys. Med. Biol., 50:4225–4241.
