- TCIA will help your technical point of contact (PACS administrator or designated IT technician, henceforth referred to as "submitter") install TCIA's software on a standard desktop computer. The software runs on regular Windows/Mac/Linux desktop computers and requires Java to also be installed. It does not require any specialized hardware (e.g. servers are not necessary).
- TCIA will help the submitter create mapping tables (which do not leave the submitting site) which our software will use to assign anonymous patient IDs and to offset study dates.
- TCIA will walk the submitter through software testing using a small sample set of their study data (e.g. 1-2 patients).
- TCIA will help the submitter export the full set of imaging studies from their local PACS (or wherever the data resides) into the TCIA software for processing.
- Note: Please do not utilize your PACS system or other de-identification software as this usually deletes critical information researchers will need to make use of the data.
- TCIA will help the submitter use the software used to de-identify and transmit images to TCIA according to DICOM standards (Attribute Confidentiality Profile – DICOM PS 3.15: Appendix E) before it leaves your institution.
- TCIA quality control and curation staff will work with you to ensure the data are fully de- identified and received. Additional reviews are performed, and any remaining PHI are deleted if found.
- TCIA will publish the final data set with a descriptive page and announce its addition via our mailing list and social media channels.

- Clinical Trials Processor (CTP)
- CTP is a stand-alone image processing application for DICOM (radiology) data. Our curation teams provide this tool to submitters in order to perform the initial de-identification of DICOM images before they are transferred to TCIA.
- CTP Wizard
- CTP Wizard is a custom extension of CTP developed by TCIA. It provides an interactive graphical user interface which can be used to more easily walk submitters through the process of importing, de-identifying, and exporting their DICOM data.
- POSDA
- POSDA (Perl Open Source Digital Imaging and Communications in Medicine [DICOM] Archive) Tools is an application for the archival and curation of DICOM datasets. After receiving the data from submitters our curation teams use POSDA to perform additional quality checks and ensure all data was completely de-identified. It allows users to import DICOM data while tracking date and time received. Users can also prioritize multiple data submission streams based on assigned priority, identify and resolve duplicate unique identifiers (UIDs) submitted with different image or metadata, and check and edit data for DICOM conformance, consistency, and referential integrity.
