SimNICT

  • SimNICT is the first dataset for training universal non-ideal measurement CT (NICT) enhancement models.

  • The dataset comprises over 10.9 million NICT-ICT image pairs, including low dose CT (LDCT), sparse view CT (SVCT), and limited angle CT (LACT), under varying defect degrees across whole-body regions.

  • We have currently uploaded part of the SimNICT dataset, SimNICT-AMOS-Sample, with preview images in the dataset viewer. The complete SimNICT dataset will be gradually uploaded in future releases.

SimNICT-AMOS-Sample

  • SimNICT-AMOS-Sample dataset contains 55 ICT volumes from the AMOS dataset in SimNICT, and each ICT volume has been simulated using the same NICT simulation method as in SimNICT, generating 9 types of NICT volumes.

  • This dataset is divided into training and test sets, with 20% and 80% of the total volumes, respectively, to evaluate the performance of our proposed MITAMP model.

Source Dataset Statistics

  • SimNICT starts from the ICT images from ten publicly CT datasets that encompass whole-body regions.
  • By removing low-quality volumes, our SimNICT dataset finally obtains 3,633,465 images from 9,639 ICT volumes.

Ongoing

  • Release the SimNICT dataset containing 10.6 million NICT-ICT image pairs.
  • Release the SimNICT-AMOS-Sample dataset, a subset of the SimNICT dataset.
