PGH_MRI
Pittsburgh MRI File Format

PGH_MRI is a data directory which contains examples of files stored in a format for magnetic resonance imaging (MRI) data. It was proposed as an intermediate format, much simpler than the standard DICOM format, but more extensible than formats such as that used by ANALYZE.

A typical dataset comprises two files:

• a header file, an ASCII formatted file, each line of which contains a keyword and value;
• a data file, a binary file containing ((X*Y)*Z)*T sets of values, representing Z slices, each an X by Y image, possibly repeated over T times.

Related Data and Programs:

ASCII_TO_MRI, a C program which restores MRI data to its original binary format, having been previously converted to an ASCII text file.

MRI_TO_ASCII, a C program which converts the binary data in an MRI file to ASCII text.

MRI_TO_PGM, a C program which converts the binary data in an MRI file to a sequence of PGM image files.

REGION, a FORTRAN90 library which reads 3D MRI voxel data, and groups the voxels into connected regions;

Sample Files:

ROI is a sample PGH_MRI dataset.

• roi.mri, the ASCII header file.
• roi.dat, the binary data file, containing (64x64) images over 26 slices.
