Cardiology Applications
is Oasis's comprehensive, vendor-neutral cardiac SPECT and SPECT/CT reconstruction application. The application is ultra-fast, taking advantage of the computer’s GPU for fully 3D implementation based on a true OSEM3D algorithm, which includes "resolution recovery" also known as "collimator deblurring". CardiacREquant uses the complete image volume in the iterative reconstruction procedure in order to increase the image quality & therefore improves the clinical reliability, diagnostic confidence and interpersonal diagnostic reproducibility. CardiacREquant
Includes Automatic Correction for:
Attenuation Correction. Scatter Correction. Depth-dependence of the point-spread function (PSF), thus reducing the collimators blur by pre-filtering the projections according to the frequency-distance principle. Statistical noise, acting on the measured projections with a secondary regularization technique. To improve gated wall motion analysis, the application uses Fourier analysis which resamples to 16-time bins in each projection angle to improve the projection quality and applies tail-drop correction in the event the patient’s heart rate varies during the acquisition. Data may be motion corrected using Cedars-Sinai motion correction module. The volume can be masked to eliminate extra cardiac activity, reoriented, and zoomed. The reconstructed series can then either be saved to the database or directly sent to third-party applications (Cedars or Corridor4DM) for quantitative analysis.
