A new method to correct the attenuation map in simultaneous transmission/emission tomography using (153)Gd/(67)Ga radioisotopes

Reconstruction of the tomographic images without attenuation correction can cause erroneously high count densities and reduced image contrast in low attenuation regions. In order to solve the problem of photon attenuation, one needs to know the attenuation coefficient for the individual patient bein...
