Citra kepala MRI pada Matlab terdiri dari 27 slice axial, 35 slice sagittal, dan 45 slice coronal.
Berikut ini source code GUI nya:
function varargout = medik(varargin)
% MEDIK MATLAB code for medik.fig
% MEDIK, by itself, creates a new MEDIK or raises the existing
% singleton*.
%
% H = MEDIK returns the handle to a new MEDIK or the handle to
% the existing singleton*.
%
% MEDIK('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in MEDIK.M with the given input arguments.
%
% MEDIK('Property','Value',...) creates a new MEDIK or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before medik_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to medik_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
