    • Medical Imaging
      • Diagnostic
        • Better than exploratory surgery

        • Produce 3D images from a large number of 2D slices
      • Assistive in surgery
    • Computed Tomography
      • Medical imaging method that uses x-rays
    • Magnetic Resonance Tomography
      • Creates images of the inside of opaque objects
      • Does not require radiation
        • Excites hydrogen nuclei in water molecules
      • Distinguishes pathological tissues from normal ones by density
      • Image
    • Ultrasound
      • Easily portable
      • Based on sound echos
    • Surgery Assistance
