What is CT file?

A .CT file is an image file. It is a bitmap raster file. It accepts a color depth of up to 32 bits. It is a specialized format used in medicine. It is mainly used to record the result of computed tomography (the English acronym CT refers to this examination). The format is related to IRIS Imaging software, but some viewers can also read the data contained in the file. It is worth noting that medical documentation is usually distributed in paper form.

How to open CT file?

The main problem with IRIS CT Image Format is that the CT file is incorrectly associated with programs. This is manifested by the fact that CT files open in unusual applications or do not have an assigned program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the CT file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install XnView

An often overlooked issue is to make sure that XnView is installed on the computer. The easiest method is to use the system search engine by entering the program name XnView in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open CT files.

Programs to open CT file

Remember to download programs supporting CT files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of XnView with CT files

If, despite the installed application, the CT file does not start in the XnView application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can select the desired program. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the CT file with the XnView application.

Step 3. Update XnView to the latest version

If, however, after binding XnView with IRIS CT Image Format there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the Pierre-Emmanuel Gougelet website and install the latest version.

Step 4. Check for the following problems with the CT file

The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. Usually this applies to CT files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. However, it is important to scan the entire system, not only the file CT or the program directory. However, remember that not every infected CT file can be recovered, so it is important to take care of regular backups.
Older version of CT file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair CT file corruption. You can restore the file from a backup or use N/A help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted CT files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. The problem is only writing to the file, not reading it. If possible, you can try to move the CT file to another location.
This can happen on a file that does not support multiple access. Some file types can only be opened in one program at a time. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the CT file for a certain period of time. If the problem persists, restart the machine.
