MRI Brain Segmentation

Neuroimaging Case Study for seminars and webinars.

| Watch this File

File Information
Description

This case study shows how MATLAB can be used for a medical imaging problem. Given an MRI scan, first segment the brain mass from the rest of the head, then determine the brain volume. Also compare portions of gray and white matter present. This example was developed for seminars. It was also used for webinars for medical applications broadcast live on May 6, 2004.

This package includes some MATLAB code and an MRI scan series consisting of 60 DICOM images. Note that this code relies on MATLAB Central submissions from others. Detailed references to those sources are included.

Required Products Image Processing Toolbox

Other requirements * Requires 2 other MATLAB Central submissions. * At least 512MB physical RAM is strongly recommended to run this example.

To fix the error:

Undefined function 'vline' for input arguments of type 'double'.
Error in thresh_tool (line 90)
h_lev = vline(my_level,'-');

Get the function vline from:

http://www.mathworks.com/matlabcentral/fileexchange/1039-hline-and-vline

To fix the error

Error using imview (line 8)
Function IMVIEW has been removed. Use IMTOOL instead.

Error in analyze_series8 (line 47)
imview(im,[0 max_level])

change the instances of imview to imtool in analyze_series8.

Hello, I am student learning medical image processing by applying matlab. When I use the function "threshold_tool' in this folder. It shows function 'vline' not defined. Is there any way can solve this problem. Thank you so much.

Sir,I am searching for segmenting white matter from a T2 weighted brain MRI scan. But I could not get the correct tutorial to follow it. Please suggest me an algorithm that works better and accurately to segment the gray matter alone from the T2 wieghted MRI scan image my mail id is:adish321309@gmail.com

Note for users who get stuck by the IMVIEW error. That function was replaced by IMTOOL (years ago). In analyze_series8.m just replace all occurrences of "imview" with "imtool" (and save).

your work is good. it is helping me a lot. but i am facing a small problem if i give input(dcm files) of larger size like 138 kb other than that you used is 129 kb. please help me out with this. i am using matlab r2008a. i get the error;

voxel_size =

0.9375 0.9375 6.0000

Name Size Bytes Class Attributes

D 256x256x12 1572864 uint16

??? Index exceeds matrix dimensions.

Error in ==> analyze_series8 at 43
im = squeeze(D(:,:,i));

after the dicom files stored are read.

It's helpful for my study in medical imaging. I've not been kowning that MATLAB could also deal with the DICOM files.
