how can we read and show CT scan files on MATLAB GUI

Hi Everybody

hope you all are enjoying good health. i took CT of a phantom and files are created in the form of .egsphant. theses are 127X127 with 55 slices. i mean i have 55 files, every file contains 127 rows and 127 columns. 127 rows and 127 columns make one image. i want to show them in MATLAB GUI. i wana open the file and using slider wanan show one by one. any help will be greatly appreciated.

There are a variety of Matlab GUIs that have been created for exactly this purpose. This search on the File Exchange found several. Try a few, and see what you prefer.

I do not recognize .egsphant as being DICOM files.

Please use the '>' button to insert formatted code. Because of the % in the code, I cannot tell which parts are intended to be commented or not.

This code does not appear to be an answer to the question that was asked in 2013 ??
