Slicer modules may also populate the DICOM database with computation results. DICOM data can enter the database either through file import or via a DICOM network transfer. Do not manually modify the contents of these directories. Each database is simply a directory on your local disk that has a few SQLite files and subdirectories to store image data. You can have multiple databases on your computer at a time, and switch between them if, for example, they include data from different research projects. To organize the data and allow faster access, Slicer keeps a local DICOM Database containing copies of (or links to) DICOM files, and basic information about content of each file. Image processing tasks most often are concerned with analyzing the whole image volume, which most often corresponds to a single Series. Those objects most often will have multiple files (instances) for each series. Most common object types are those that store the image volumes produced by the CT and MR scanners. There is a variety of DICOM objects defined by the standard. Instance (most often, each Series will contain multiple Instances, with each Instance corresponding to a single slice of the image)Īs a result of imaging exam, imaging equipment generates DICOM files, where each file corresponds to one Instance, and is tagged with the information that allows to determine the Series, Study and Patient information to put it into the proper location in the hierarchy. Series (single image acquisition, most often corresponding to a single image volume) … can have 1 or more Study (single imaging exam encounter) … can have 1 or more In most cases, imaging equipment (CT and MR scanners) used in the hospitals will generate images saved as DICOM objects.ĭICOM organizes data following the hierarchy of Slicer provides support for the most commonly used subset of DICOM functionality, with the particular features driven by the needs of clinical research: reading and writing data sets from/to disk in DICOM format and network transfer - querying, retrieving, and sending and receiving data sets - using DIMSE and DICOMweb networking protocols.ĭigital Imaging and Communications in Medicine (DICOM) is a widely used standard for information exchange digital radiology. This module allows importing and exporting and network transfer of DICOM data.
