What is a(n) CT file?
The CT (IRIS CT Image Format) is a type of computer file used to store images from a computed tomography scan. It is most commonly used for medical imaging applications, such as CT scans of the head, chest, and abdomen. These files can retain all of the data associated with a CT scan, including the x-ray attenuation values for each voxel in the scan. The CT file format is compatible with most devices and software programs and allows for easy sharing and viewing of images.
CT files are often stored with extension .v or .mda and typically include additional information such as the patient’s name, date/time of the scan, manufacturer/model of the scanner used, generating program, etc. They can be compressed with various lossless compression techniques to reduce their size and conserve storage space. The data contained within a CT file can be extracted and further manipulated using specialized software.
