Detection and determination of brain tumor from MRI of brain and its volume calculation

Abstract EN

Brain tumor detection is one of the challenging tasks in medical image processing.

The main purpose of this paper to design and implementation automatic system for brain tumor detection and its determination using MR images.

The acquired MR images are processed using digital image processing techniques.

These images are preprocessed and then segmented by threshold and watershed segmentation, after that, the morphological operations are used to extract only tumor in brain image automatic.

Also, the region of interest algorithm (ROI) is used to extract tumor portion using a cursor, then compute the calculation volume of the tumor extracted automatically and compute the calculation volume of the tumor extracted by ROI to compare between these volumes.

The location of tumor in brain is very important, so the proposed algorithm is to determine the location of tumor in MRI brain image.

Results obtained were good compared with the review researches results.

A detailed procedure using Matlab (R2010a) software is written to extract tumor region in MRI Scan Brain Image, MRI are used because MRI Scan has higher resolution and easier identification.
