Module Description

This module was developed to detect epileptogenic focus candidates using SPECT images. A MRI image can also be used. Below you will find a description of the functionality of the module.

Use Cases

Compare candidates obtained using SISCOM and a-contrario method.

Panels and their use

• Load Studies: The following studies are required:
  • SPECT basal
  • SPECT ictal
  • MRI (optional: for visualization of the results or SPECT/MRI registration)
• Registration: To compare the basal SPECT and the icatl SPECT the volumes must be registered. In this step it is possible to perform:
  • SPECT basal/SPECT ictal registration
  • SPECT/MRI registration (if MRI Available)
  • SPECT basal/SPECT ictal mask (intersection) computation
• Foci detection: Differential (SISCOM) and a-contrario methods are implemented. Results can be visualized in MRI Space (if available) or SPECT Space. Results can be compared.
  • Differential method: Given two SPECT images (basal and ictal) in the same space (already registered), the images are substracted. An intensity normalization step is applied.
  • A-contrario: to be described
