The problem of model falsification or model invalidation appears in several areas where we are interested in distinguishing among an eligible set of dynamic systems. In the context of fMRI studies of brain activity, modeling the haemodynamic response function (HRF) is a critical step. The estimation of the dynamic system describing a biophysical model of the HRF may leave much uncertainty on the exact...
Pre-operative neurosurgical planning often uses data from functional magnetic resonance imaging (fMRI) to identify areas of eloquent cortex, such as the primary and secondary somatosensory cortices, to be spared during surgery. However, the in-vivo visualization of subcortical neurosurgical targets has typically involved the warping of subcortical atlases or T2- and diffusion-weighted imaging techniques...
The Siemens microPET family of scanners provides for acquiring a measured attenuation correction using a 57Co point transmission source that spirals around the field of view (FOV). The standard transmission source mechanism advances the source 0.5 mm for every spiral about the FOV. The transmission scan measurement requires approximately 10 minutes, so that often in the interest of time it is not...
