  1. User Interface for Brain CT Analysis GROUP : PA4

  2. Motivation  The motivation of this project is to help the doctor to diagnose the disease more easily.

  3. Purpose  To write Matlab programs to create the GUI for creating the 3D model of a brain from the slices of CT scan input.  To help the doctor to calculate the volume of the brain.

  4. Why Using Matlab ?  Contain many useful mathematical computing functions.  It provides interactive tools such as filtering, Fourier analysis, matrix analysis, 2D and 3D plotting functions.  It has GUI function.

  5. Brain CT scan  CT stands for Computed Tomography .  CT scan of the head is a diagnostic tool used to create detailed pictures of the skull, brain , ventricles of brain and tumor.

  6. Example of CT slices.

  7. How to Plot 3D Model Find the contour of the brain.

  8. How to Plot 3D Model  The ezsurfc(f) or surfc function creates a graph of f(x,y), where f is a string that represents a mathematical function of two variables, such as x and y

  9. How to Plot 3D Model  Creates a three-dimensional contour plot of a surface defined on a rectangular grid.

  10. How to Plot 3D Model  3-D Lit Surface Plot (Surface plot with colormap-based lighting, surfl function) displays a shaded surface based on a combination of ambient, diffuse, and specular lighting models.
