Q

CT Scan

A

(Computed Tomography) is a special type of X-Ray machine. Rather than a single X-Ray (traditional X-Ray), several beans are send simultaneously from different angles.

  • Far more detailed
  • Images from two-dimensional scans can be reconstructed into 3-D images.

  • Face 2 - hurts a little more
  • Face 3 - hurts even more
  • Face 4 - hurts a whole lot
  • Face 5 - hurts as much as you can imagine (although do not need to be crying to hurt this bad)
