Change canvas size for all images in a dicom image set.

[John Thaman]

Greetings,

I am looking to use imagej to change the canvas size for a large set of DICOM images.The actual goal is to change the images suchthat they have equal numbers of columns and rows without changing the aspect ratio of the data. I can do this manually by changing canvas size and saving each individual image/slice. I am receiving increasingly larger image sets and wishto utilize a plugin or macro that will do this for me. Please advise if you know of an available tool.

Thank You

You can do this using the macro below.

-wayne

  w = 1024;
  h = 1024
  dir1 = getDirectory("Choose Source Directory ");
  dir2 = getDirectory("Choose Destination Directory ");
  list = getFileList(dir1);
  setBatchMode(true);
  for (i=0; i<list.length; i++) {
     showProgress(i+1, list.length);
     open(dir1+list[i]);
     run("Canvas Size...", "width=&w height=&h position=Center zero");
     saveAs("tiff", dir2+list[i]);
     close();
  }
