在CT图像中分割肺和结节 [英] Segmenting Lungs and nodules in CT images

问题描述

我是Matlab中图像处理的新手，我试图从CT图像中分割LUNG和结节。我已经完成了初始图像增强。

I am new with Image processing in Matlab, I am trying to segment LUNG and nodules from CT image. I have done initial image enhancement.

我搜索了相同但我没有找到任何相关资料。

I searched lot on the same but I haven't found any relevant materials.

尝试从给定图像中分割肺部分;然后检测肺部的结节。

Trying to segment lung part from the given image; and then detecting nodules on Lung part.

我在Matlab中尝试的代码：

Code I tried in Matlab:

d1 = dicomread('000000.dcm'); 
d1ca = imadjust(d1); 

d1nF = wiener2(d1ca);

d1Level  = graythresh(d1nF);
d1sBW = im2bw(d1nF,d1Level); 
sed = strel('diamon',1); 
BWfinal = imerode(d1sBW,sed);
BWfinal = imerode(BWfinal,sed);

BWoutline = bwperim(BWfinal);
Segout = d1nF;
Segout(BWoutline) = 0; 

edgePrewitt = edge(d1nF,'prewitt'); 

上述代码的结果：

我知道专家可能很容易。请帮帮我。

I know its may be easy for experts. Please help me out.

谢谢！

推荐答案

试试这个：

% dp6BK.png is your original image, I downloaded directly
I = im2double(imread('dp6BK.png'));  
I=I(:,:,1);
imshow(I)


cropped = I(50:430,8:500); %% Crop region of interest   
thresholded = cropped < 0.35; %% Threshold to isolate lungs
clearThresh = imclearborder(thresholded); %% Remove border artifacts in image   
Liver = bwareaopen(clearThresh,100); %% Remove objects less than 100 pixels
Liver1 = imfill(Liver,'hole'); % fill in the vessels inside the lungs
figure,imshow(Liver1.*cropped)
