Introduction
Researchers in medicine often need to anonymize DICOM datasets before use them in their studies due to HIPAA regulations. MaskIt is a free lightweight DICOM anonymizer for all DICOM modalities. It runs on Windows platforms. The current version is 5.0 released on April 28, 2025.
To help you check the integrity of a dataset, DICOM objects will be sorted and presented in a hierarchical structure in which they were actually internally articulated. DICOM objects of commonly used modalities are indicated in distinctive icons for you to get a good picture of the dataset.
