Question

Construct pseudocolor images

using these brain data

t1,t2, flair in.nic.form

if you know then only try or else leave for others

IMAGE PROCESSING,ELECTRICAL

Answer 1

As the image is in .nii format we have to read it by using this command.
[V info]=ReadData3D('Brats17_TCIA_103_1_flair.nii');
f=V(:,:,85);
f=imrotate(f,-90);
f_range=abs(max(max(f))-min(min(f)));
f_2=240*f/f_range;
%filtering it to remove noise
f=imgaussfilt(double(f),0.9);
[V1, info1]=ReadData3D('Brats17_TCIA_103_1_t1ce.nii');
t1=V1(:,:,85);
t1=imrotate(t1,-90);
t1_range=abs(max(max(t1))-min(min(t1)));
t1_2=240*t1/t1_range;
%t1=imgaussfilt(double(t1),0.9);
[V2, info2]=ReadData3D('Brats17_TCIA_103_1_flair.nii');
t2=V2(:,:,85);
t2=imrotate(t2,-90);
t2_range=abs(max(max(t2))-min(min(t2)));
t2_2=240*t2/t2_range;
% t2=imgaussfilt(double(t2),0.9);
%concatenated to form pseudo rgb
rgb1=cat(3,t2_2,f_2,t1_2);
r=rgb1(:,:,1);
g=rgb1(:,:,2);
b1=rgb1(:,:,3);
