PET emission scans were acquired for 30 min, preceded by CT scans (spatial resolution 113 μm, 80 kV, 500 μA, exposure time 300 ms).
The groups were scanned using spatial scan statistic to detect high prevalence clusters of cases.
This paper proposes a scanning spatial-wavenumber filter and piezoelectric sensor (referred to as PZT) 2-D cruciform array based on-line damage imaging method of composite structure.
Each patient's MRI scan underwent spatial normalization using SPM2 software in order to match and align images on a common Talairach space (Talairach and Tournoux, 1988).
The set of all windows to be scanned by the circular spatial scan statistic is denoted by S1 = { S i : j ; i = 1,..., m; j = 1,..., J}.
The set of all windows to be scanned by the flexible spatial scan statistic is then S2 = { S i : j (k ); i = 1,…, m; j = 1,…, J; k = 1,…, k ij }.
With Project Tango, Google has shown an interest in this space, too, though it has remained relatively quiet about its own mobile 3D scanning and spatial computing efforts.
For both random search and scanning any spatial or even directional preference is absent.
The preprocessing (SPM2) steps included realignment, coregistration of the anatomical images to the functional scans, and spatial normalization into the standard Montreal Neurological Institute (MNI) space.
This window is either an interval in time (for temporal scanning), a circle (for spatial scanning) or a cylinder with a circular spatial base and a time interval as its length (for spatio-temporal scanning).
The spatial scan statistic uses a scanning window that moves across space.
