What Is a CT Scan Machine?

A CT scan machine is a medical imaging system that combines an X-ray source and detector array with computer-based image reconstruction.

During an examination, the scanner collects X-ray measurements from multiple angles. A computer processes this information to create cross-sectional images that can also be reconstructed into different planes or three-dimensional views.

CT imaging is used across areas such as:

• Emergency and trauma imaging
• Neurological imaging
• Cardiac imaging
• Oncology imaging
• Pulmonary imaging
• Vascular studies
• Musculoskeletal imaging
• Radiation therapy planning

The exact capabilities vary according to the CT system, software, clinical protocol, and healthcare facility.
