Simultaneous recovery of attenuation and source density in SPECT
Sean Holman, Philip Richardson
We show that under a certain non-cancellation condition the attenuated Radon transform uniquely determines piecewise constant attenuation and piecewise source density …

Emission tomography with a multi-bang assumption on attenuation
Sean Holman, Philip Richardson
We consider the problem of joint reconstruction of both attenuation and source density in emission tomography in two dimensions. This is sometimes called the Single Photon…
