The file given here Medical Image File has a format *.gz, it is a compressd file. After unzipping I found some file without extension. It has given in the link that the file has properties mentioned below.
  • DICOM
  • Implicit Little (raw)
  • CR
  • MONOCHROME1
  • 440x440
  • [10, 16 | 9], PR=0
  • Fuji photo film Co.

Please let me know If there is anyway to convert it into .png format.

% 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);

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);
