Sedeen supports many image formats to make multimodality registration possible, such as:

  • A variety of whole slide images
  • Radiology images in DICOM format
  • Generic TIFF and JPEG-2000 images
  • Variety of small formats such as JPEG and PNG images

The image overlay system can be used for many applications including:

  • Alignment of serial sections
    • H&E with H&E
    • H&E with IHC

  • Multimodality biomarker validation
    • Protein expression and colocalization (e.g. H&E and IHC) 
    • Radiology and histology

This video shows how to register and overlay two slides.
