deleteContour

Delete ROI sequence from ROI data

collapse all in page

Syntax

contourOut = deleteContour(contourIn,number)

Description

contourOut = deleteContour(contourIn,number) deletes one or more region of interest (ROI) sequences extracted from a DICOM-RT structure set file. Specify each sequence to delete by the ROI number number.

Use the deleteContour function to delete an ROI sequence from the ROIs property of a dicomContours object. You can then use the convertToInfo function to export the new ROI data to the structure set and ROI contour modules of DICOM metadata.

Read the DICOM metadata from a DICOM-RT structure set file.

info = dicominfo("RTSTRUCT-VS-SEG-001.dcm");

Extract ROI data from the structure set and ROI contour modules of the DICOM metadata. The output is a dicomContours object that stores the extracted ROI data.

contourIn = dicomContours(info);

Display the ROIs property of the dicomContours object.

      2       {'Cochlea'}    { 5×1 cell}     { 5×1 cell}     {3×1 double}
      3       {'Vol2016'}    {12×1 cell}     {12×1 cell}     {3×1 double}
      4       {'*Skull' }    {79×1 cell}     {79×1 cell}     {3×1 double}

Delete the ROI sequence specified by ROI number 2.

contourOut = deleteContour(contourIn,2)
contourOut = 
  dicomContours with properties:

    ROIs: [3×5 table]

Display the ROIs property of the output dicomContours object. You can use the convertToInfo function to export the modified ROI data to a DICOM-RT structure set file.

Input Arguments

collapse all

Input ROI data, specified as a dicomContours object.

ROI number, specified as a numeric scalar or vector. Specifying a vector of ROI numbers deletes multiple ROI sequences.

The ROI number is specified in the Number column of the table returned by the ROIs property of the dicomContours object.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64

Output Arguments

collapse all

Output ROI data, returned as a dicomContours object.
