What is CAT- Scan?

  • CAT-Scan is composed of X- ray equipment to create 3D images of organs, bones, soft tissues, fat etc using automated axial tomography. CAT-Scan is also referred as CT-scan which stands for Computed tomography.
  • CT scans provide more clarity than X-Rays and it is easy to detect problems like cancers, cardiovascular disease, infectious disease, appendicitis, trauma and musculoskeletal disorders.
  • CAT-Scans are classified in to various generations. At first CT scan requires around five to six to complete the scan by pressing the patients head beside a rubber membrane. In the latest generation thin X-ray and single detector are used for scanning.
  • In the second generation full body CT scans were introduced and 20 or more X-ray beams and detectors were used which improved the quality of the image greatly.
  • Many developments were made in the present day CT scan device and you can complete the entire scan of the body within one-third of a second.
  • Patients lie down on a flat platform of the CT scan device and the platform is passed through the tunnel in the CT scan device.
  • X-rays are produced from CT scan device which scans the body from different angles. X-rays are pass through the human body which contains high energy photons and then the computer gathers all the information and creates the 3D image of the body.
