CT imaging was performed first and immediately followed by PET imaging with the subject's body position secured to maintain coregistration.
18F] fuorodeoxyglucose-positron-emission tomography and MR imaging coregistration for presurgical evaluation of medically refractory epilepsy.
As we have noted, our biopsies to date have largely been via cognitive coregistration and thus can be theoretically prone to misses, particularly as we identify smaller lesions.
A dual screen station or a server for viewing fusion and image processing, including coregistration, to the doctor, with associated software; this station will also include software for monitoring of patients with previously drawn ROIs storing and resetting of the last acquisition, simultaneous display with melt (PET / CT / MRI) of at least 3 tests;
All sequences were performed during suspended respiration at end expiration to optimize image coregistration for subtraction algorithms.
For coregistration and normalization purposes, a high-resolution Tl-weighted structural image with good gray/white matter contrast was acquired using a three-dimensional magnetization-prepared rapid-gradient echo sequence with the following protocol: matrix size = 256 x 256 x 208, FOV = 21 cm, TR = 2,500 msec, TE = 4.
The DEM was used to ortho-rectify the aerial photographs for precise GIS coregistration.
The Simulated Brain Database (2) presents us with convenient data consisting in three modalities (PD, T1, T2) that, being simulated, are in perfect coregistration [20].
18]F-DOPA, and coregistration of PET and CT images allows the anatomical localization of the lesion.
While selection of the optimal GPS receiver is a project-dependent consideration, the data we present is important for GIS managers to help them: (1) understand the differences in horizontal positional accuracy obtained from various GPS receiver types; (2) ensure coregistration of GPS-acquired features and satellite or aerial imagery; and (3) determine the appropriate GPS receiver to use to satisfy mapping scale requirements.

All of the study participants underwent PET scans, both before and after completing a continuous performance task, and MRI scans, for structural coregistration of the PET data.
