Medical Imaging
Diagnostic Better than exploratory surgery Ability to “see” soft tissues 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
Laparoscopic Surgery Fiber optic system allows surgeon to
see through a video feed Uses long thin instruments 2001: first transatlantic surgery was a
laparoscopic gall bladder removal Laser eye surgery
Requires precise direction of laser
Remote surgery

were actually at another place Telerobotics: an agent at the other
end to perform the tasks
Virtual Environments
Usually requires head mounted display Displays images that you would see Adjusts the images as you move
Also: Haptic feedback Audio placement Smells
Virtual Environments: Other Uses
Training Simulators Urban fighting Emergency teams
Acclimation Overcoming phobias Preparation
