dicomCollection

Gather details about related series of DICOM files

Description

example

collection = dicomCollection(directory) gathers details about the DICOM files contained in directory and returns the file details in the table collection. The dicomCollection function aggregates details by DICOM series, using the value of the SeriesInstanceUID metadata field in each file to determine series membership. A DICOM series is a logically related set of images from an imaging operation.

collection = dicomCollection(directory,"IncludeSubfolders",tf) recursively searches for DICOM files below directory when tf is true (the default). When tf is false, dicomCollection searches only within directory.

example

collection = dicomCollection(DICOMDIR) gathers details about the DICOM files referenced in the DICOM directory file DICOMDIR. A DICOM directory file (DICOMDIR) is a special DICOM file that serves as a directory to a collection of DICOM files stored on removable media, such as CD- or DVD-ROMs.

Input Arguments

collapse all

Name of a folder containing DICOM files, specified as a string scalar or character vector.

Example: details = dicomCollection(fullfile(matlabroot,"toolbox/images/imdata"))

Data Types: char | string

DICOM directory file, specified as a string scalar or character vector.

A DICOM directory file (DICOMDIR) is a special DICOM file that serves as a directory to a collection of DICOM files stored on removable media, such as CD- or DVD-ROMs. When devices write DICOM files to removable media, they typically write a DICOMDIR file on the disk to serve as a list of the disk contents.

You can specify DICOMDIR using its absolute path, relative path, or location on the MATLAB path.

Example: details = dicomCollection(fullfile(matlabroot,"toolbox/images/imdata/DICOMDIR"))

Data Types: char | string

Include subfolders in search, specified as a logical 1 (true) or 0 (false). When set to true, the dicomCollection function recursively searches for DICOM files below directory. When set to false, the dicomCollection function only includes files within directory in the search.

Data Types: logical

Output Arguments

collapse all

Metadata from DICOM files, returned as a table. The dicomCollection function aggregates the information by DICOM series.
