Motion compensated gated PET image reconstruction methods include joint-reconstruction (JR) and indirect reconstruction (IR) with pre-estimated motion from MRI (MRI-IR). JR suffers from poor PET data quality whereas MRI-IR requires high-quality MRI volumes at each gate. We propose a penalised maximum-likelihood approach combining JR and MRI-IR. Our method(More)
In a brief two year period, magnetic resonance imaging of the spine has developed from a single slice, low signal/noise ratio, extremely time consuming technique to a multiplanar, high resolution examination that can be performed in a time frame similar to that of CT imaging. MR has already assumed a primary imaging role in myelopathic states. It is(More)
