Create Image Datastore Containing DICOM Images

This example shows how to create an image datastore from a collection of DICOM files containing 2-D images. To learn more about organizing images labeled using the Medical Image Labeler (Medical Imaging Toolbox) app, see Create Datastores for Medical Image Semantic Segmentation (Medical Imaging Toolbox).

Specify the location of a directory containing 2-D DICOM image files.

dicomDir = "dog";

Create an imageDatastore object, specifying the read function as a handle to the dicomread function.

dicomds = imageDatastore(dicomDir, ...
   FileExtensions=".dcm",ReadFcn=@(x) dicomread(x));

Read and display the first image in the datastore.

I = read(dicomds);

Display the image. The image has signed 16-bit data, so scale the display range to the pixel values in the image.
