% Read existing image.
theImage = dicomread(existingFullFileName);
% Get the base file name
[folder, baseFileName, ext] = fileparts(existingFullFileName);
% Create a new PNG name for it.
fullFileName = fullfile(folder, [baseFileName, '.png']);
% Save it to disk
imwrite(theImage, fullFileName);

HI there

what does this means :

[folder, baseFileName, ext] = fileparts(existingFullFileName);

i am receiving error because of it.

thanks

It breaks the filename up into components: the folder, the base file name without any file extension, and the extension. What error do you have? Is existingFullFileName a string that you have in your program with some filename in it? Unfortunately you've delayed an answer because you forgot to give me the error message and your code (so I can see what existingFullFileName is).

Hi there

Sorry for my unclear question.

can you please show how can i use this code if i want to convert my dicom file to png ?. My file name is (chest.dcm).

[Image Analyst]

My code did that. Here it is again:

% Read existing image.
theImage = dicomread(existingFullFileName);
% Get the base file name
[folder, baseFileName, ext] = fileparts(existingFullFileName);
% Create a new PNG name for it, this time with a png extension.
fullFileName = fullfile(folder, [baseFileName, '.png']);
% Save it to disk in png format.
imwrite(theImage, fullFileName);
