MRI Brain Segmentation

Neuroimaging Case Study for seminars and webinars.

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
• MATLAB release: MATLAB 7 (R14)
• Other requirements: * Requires 2 other MATLAB Central submissions. * At least 512MB physical RAM is strongly recommended to run this example.

program with Matlab software for leaf classification & image segmentation
thanks alot

[Jiang Yun]

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

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.

[Preeti]

i am getting the error in imtool and not able to remove even downloading the patch as advised. please help.

[Robert Bemis]

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).

it's very good tutorial. Very good coding for matlap brain image processing.
but can you help how to segmenting brain white matter, gray matter and cerebrospinal fluid. if you have algoritm or code in matlab, help give me.
i really need....
