Phantom to mimick Multiple Sclerosis (MS) Lesions
==================================
This directory contains the following files in zipped form:
phantom_FLw.raw
phantom_T2w.raw
phantom_PDw.raw
ReadMe.txt

This data set was created from a phantom that was designed to 
mimic the MS lesions in brain MR scans. The true volume of lesion 
is 29.5 cc. The phantom was designed such that the simulated lesions 
had  contrast comparable to the ones seen in routine clinical cases.
Three scans, one each for FLAIR (Fluid Attenuated Inversion Recovery), 
T2 and PD (proton density) sequences were scanned.

The three series are:
===============
Flair series = phantom_FLw.raw
T2 series = phantom_T2w.raw
PD series = phantom_PDw.raw

The information common to all the files is described as follows:
=============================================
Number  of Slices = 11
Each image = 256 x 256
Each pixel = 2 bytes
Big endian
spacing[ x, y, z] = [0.078 cm, 0.078 cm, 0.03 cm]

The information specific towards the particular series:
