Sentence examples for reconstruct activity from inspiring English sources

A modified MLAA algorithm [15] is used to simultaneously reconstruct activity and attenuation distributions from the PET emission data.

We also note that recent MEG studies [ 7, 18 21] report being able to reconstruct activity in the amygdala and hippocampus, as well as in thalamic [ 22] and brainstem structures [ 23].

The proposed approach simultaneously reconstructs activity and attenuation distributions from the PET emission data.

The coefficient of variance (CV) was calculated for small overlapping volumes covering the 3D reconstructed activity distribution.

Figure 6 shows the FWHM of the reconstructed activity distribution in the xy plane (perpendicular to x-ray beam) as a function of distance from the pinholes.

Emission-based AC exploits this fact, simultaneously reconstructing activity and attenuation distributions from either time-of-flight (TOF) [16 19] or non-TOF [20] PET emission data.

The FWHM was calculated by extracting profiles from the reconstructed activity distribution through the maximum voxel in the x and y direction, which were fitted with a Gaussian.

Briefly, the coefficient of variation (CV) is calculated for overlapping cubic volumes (1 coveringering the 3D reconstructed activity distribution in the segmented lung, creating a 3D CV matrix.

Briefly, the coefficient of variation (CV = the standard deviation divided by the mean) is calculated for overlapping cubic volumes covering the 3D reconstructed activity distribution.

The sinograms correspond to the same transversal plane as shown in (a). Figure 9 shows the effect of the different attenuation maps on the reconstructed activity distribution.

Due to the limited spatial resolution of the SPECT system, the reconstructed activity distribution is blurred which is most clearly seen at the edge of the lung.
