CAT scans

• what does a CAT scan use to take pics?

  • X-ray technology
• what does the X-ray technology do?

  • takes multiple images of the body at different angles, like taking slices of the body to build a 3D picture
• what does a CAT scanner look like?

  • large
• how does a CAT scanner work?

  • has a tube that rotates around the patient
• what does the X-ray tube emit?

  • as it rotates the x-ray tube emits x-rays
• how does a CAT scan capture the X-rays?

  • Emits X-rays that pass through the body and are detected by sensors on the other side.
  • The sensors capture the X-rays at different angles and send this information to a computer.
• what happens with the info of a CAT scan after its reached the computer?

  • takes the data from all these angles
  • combines them to create a cross-sectional image of the body part being scanned.
  • It produces detailed, 2D cross-sectional images
• what are advantages of CAT scans?

  •  useful for revealing abnormal brain structures, such as tumors, bleeding, or strokes.
  • CAT scans provide higher quality images than regular X-rays, especially for soft tissues and internal organs.
  • Quick and Non-invasive: The scan is relatively quick and doesn’t require any invasive procedures like surgery.
  • Useful in Emergencies: CAT scans are often used in emergency situations, as they provide fast results to help diagnose conditions quickly.
• what are the disadvantages of CAT scans?

  • use more radiation than regular X-rays, and the more detailed the scan, the more radiation is required.
  • Only provide structural images, but they don’t show brain activity or chemical information
  •  less detailed than MRI scans for soft tissues like the brain or muscles.
