  • 1. CT Scanner Solution
    • Source: Texas Instruments
  • 2. Introduction
    • Purpose
      • CT Scanner Solution from TI
    • Outline
      • Introduction to CT scan, detectors
      • Image Reconstruction and spiral type of CT
      • Block diagram of CT
      • Solution for CT from TI Data converters, Processor, Power management
      • Solution of DSP, processor, touch screen, ADC and other peripherals from Premier Farnell
    • Content
      • 23 pages
  • 3. What is CT scanning?
    • A technique to help locate a problem and confirm diagnosis in order to give the correct treatment.
    • The x-ray tube rotates around the body, the x-rays pass through and cross sectional images (pictures) of tissues are formed.
    • The computer makes multiple pictures.
    • The X-rays from the beam are detected after they have passed through the body and their strength is measured.
    • Beams that have passed through less dense tissue such as the lungs will be stronger, whereas beams that have passed through denser tissue such as bone will be weaker.
    • The computer processes the results, displaying them as a two-dimensional picture shown on a monitor.
  • 4. Overview of Computed Tomography (CT)
    • The amount of x-rays used are carefully calculated to reduce the amount of radiation needed, to be as safe as possible and to obtain a good image.
    • The scanner can be tilted forwards and backwards to allow the x-rays to reach the area to be scanned.
  • 5. Types of Detectors
    • Two types
    • 1. Scintillation crystals- Bismuth germanate crystals coupled with photomultiplier or sodium iodide crystals, are more efficient and has less afterglow .
    • 2. Ionization chamber containing xenon gas under pressure, they have no afterglow but are slightly less efficient.
  • 6. Image Reconstruction
    • Image is first converted to digital image and then to conventional gray scale image
    • Image of the section is broken down in ,
    • Tiny picture elements called pixels,
    • Projection of solid cores of tissues called voxels.
    • Computer counts the light flashes in solid detectors & ions in ionization detectors and gives them a CT number according to there attenuation coefficients
    • Reconstruction of whole image of the section by multiple projection is a complex and is done by computer. One of the method is back-projection.
    • Contrast can be adjusted by operators
  • 7. Spiral CT
    • Newer method
    • X-ray tube moves continuously with slip-ring technique, the outer fixed detector ring and inner rotating x-ray tube ring having brushes that remain in electrical contact with the inside of outer ring.
    • X-ray tube moves continuously with patient moving cephalad with constant rate producing a spiral or helix around the patient.
    • Tube is energized for as much as 30 sec at a time as compared to conventional which is energized for 1 sec.
    • Reconstruction is by interpolation i.e. calculation of intermediate values in a series.
    • It has 3 dimensional image constructed
  • 8. Computed Tomography System Block Diagram
