interfileread

Read images in Interfile format

Description

I = interfileread(filename) reads the images in the first energy window of the Interfile image file specified by filename.

The Interfile file format was developed for the exchange of nuclear medicine data. In Interfile 3.3, metadata is stored in a header file, separate from the image data. The two files have the same name with different file extensions. The header file has the file extension .hdr and the image file has the file extension .img.

I = interfileread(filename,window) reads the Interfile image data in the energy window specified by window.
