import and spatial referencing -凯发k8网页登录

read images and spatial metadata from medical imaging file formats

medical imaging toolbox™ supports specialized file formats that store medical image data and metadata that describes the patient, imaging procedure, and spatial referencing. spatial referencing specifies the location of an image in the patient coordinate system, which is defined relative to the anatomical axes of the patient. the medicalvolume and medicalimage objects automatically parse metadata to import and store image data and spatial information from dicom, nifti, and nrrd files. you can also read the image and metadata separately using functions for each file format.

functions

import and work with medical images

	2-d medical image pixel data and file metadata
	extract pixel data for one frame of 2-d medical image series
	display medical image slices or frames as montage in patient coordinates

import and work with medical volumes

	3-d medical image voxel data and spatial referencing information
	extract voxels and spatial details for one slice of medical volume
	display medical image slices or frames as montage in patient coordinates
	replace voxel values for one slice of medical volume
	resample medical image volume in different patient coordinate system
	extract coordinates of corner voxels for one slice of medical volume
