| # 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**](#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**. |
