Instructions

This software requires CTA brain images in compressed NIFTI format (i.e. with a nii.gz extension) that have been pre-registered to a common brain template. The brain templates are available here and here.

We have developed a point and click pipeline to perform the NIFTI format conversion, automatic registration and anonymization. It is available at https://github.com/lgiancaUTH/preproc__cta_core . A video showing how to use the pipeline works is available here.

If you would like to quickly test the software, you can download two example CTAs that have been already registered to the template: here and here . A video showing how to use this Web App is available here.

Image Upload

Select your CTA image and upload it using the button below. The images need to be registered to a custom template, click here for more information. You can test our system using an example image. You can upload up to 5 images.

optionally insert email to be notified of end of processing (useful when uploading many images at once)
