The term 'KIND OF SCAN' can be broken down into two crossword solutions: RETINAL (7 letters) and CAT (3 letters). A Retinal Scan is a type of eye scan that uses a low-energy laser beam to take a high-resolution image of the retina, which is the light-sensitive tissue at the back of the eye. A CAT Scan, or Computed Axial Tomography Scan, is a type of imaging test that uses X-rays and a computer to create detailed images of the inside of the body. Both of these scans are used to diagnose and monitor medical conditions.
