Why OASIS for Neurology?
Strategically designed with technologists and physicians in mind, Oasis provides a high-quality system with an innovative solution for processing, 3D image rendering, fusion display, and in-depth quantitative analysis available for our various neurology applications.
Support of all major cerebral tracers—HMPAO, ECD, FDG (Currently only FDG is approved for clinical use June 2022)
Uses templates for PET and SPECT, and affine registration, to map the patient brain to the Montreal (MNI) space
Montreal Neurological Institute’s mapping of functional regions
Patient brain is compared to 20 normal subjects closest in age
Choice of normalization methods: to max in Cortex, max in Cerebellum, histogram, etc.
Two methods of analysis: cortical surface profile (with adjustable depth) and voxel by voxel
3D surface rendering display of results, with color-coded deviation from normal
Right to Left comparison
Slice display, with color-coded deviation from normal
Excel sheets containing exhaustive presentation of the extent and severity of perfusion defects in all functional areas, right and left, and R/L asymmetry index
Fusion with MRI data; if the patient does not have an MR series, a template is used
CerQuant
CerSPECT
Qualitative reviews of Brain SPECT and PET studies
Chang Attenuation Correction
Integrated reconstruction of raw projection data using FBP or OSEM
Standardized orthogonal slice displays
Display functions: triangulation, window leveling, color-scale
selection, slice alignment, cine controls, zoom, pan, magnify, colorize
Specialized light-box displays including temporal lobe slices
Maximum intensity projections
Multi-threshold 3D iso-contour displays for improved visualization of areas of hypo- and hyper perfusion
Study comparisons (baseline/activation, Diamox protocol, follow-up)
Compatibility with most acquisition protocols (matrix size)
Customized layouts through display scripts.
SISCOM™
Neuroimaging for Epilepsy
Comparison of Ictal and Inter-ictal SPECT images
Automatic co-registration of SPECT images with MRI
Display delta results of registered Images
Fuse/Superimpose delta images with MRI

Predefined structures, arterial terrains, and Broadmann areas for quantitative analysis
Automatic co-registration with MRI
Study comparison (baseline/activation, Diamox protocol, follow-up) with normalized subtraction displays
Compatibility with most acquisition protocols (matrix size)
Customized layouts through display scripts.
